Description

Detailed Description of the Invention

FIELD OF THE INVENTION The present invention relates to newly identified polynucleotides, and the polypeptides encoded by these polynucleotides, the use of such polynucleotides and polypeptides, and their production.

BACKGROUND OF THE INVENTION Unlike bacteria, which exist as a single compartment surrounded by a membrane, human cells and other eukaryotic cells are subdivided by the membrane into many functionally distinct compartments. Each membrane-separated compartment, or organelle, contains different proteins that are essential for that organelle's function. Cells use "sorting signals," which are amino acid motifs located inside proteins, to target the protein to specific cellular organelles.

One type of selection signal, called a signal sequence, signal peptide, or leader sequence, directs a class of proteins to the organelle called the endoplasmic reticulum (ER). The ER separates membrane-bound proteins from all other types of proteins. Once localized to the ER, both groups of proteins can be further directed to another organelle called the Golgi apparatus. Where Golgi is
The protein is distributed in vesicles, including secretory vesicles, cell membranes, lysosomes, and other organelles.

Proteins targeted to the ER by signal sequences can be released into the extracellular space as secreted proteins. For example, vesicles containing secreted proteins can fuse with the cell membrane and release their contents into the extracellular space, a process called exocytosis. Exocytosis can occur constitutively or after receipt of an evoked signal. In the latter case, the protein is stored in secretory vesicles (or secretory granules) until exocytosis is triggered. Similarly,
Proteins that reside on cell membranes are also “linkers” that hold the protein to the membrane
It can be secreted into the extracellular space by proteolytic cleavage of.

Despite significant advances in recent years, only a few genes encoding human secretory proteins have been identified. These secreted proteins include commercially valuable human insulin, interferon, factor VIII, human growth hormone, tissue plasminogen activator, and erythropoietin. Thus, given the widespread role of secreted proteins in human physiology, there is a need to identify and characterize new human secreted proteins and the genes that encode them. This finding makes it possible to detect, treat and prevent medical diseases, disorders and / or conditions by using secreted proteins or the genes encoding them.

SUMMARY OF THE INVENTION The present invention relates to novel polynucleotides and their encoded polypeptides. Further, the invention relates to vectors, host cells, antibodies and recombinant and synthetic methods for producing the polypeptides and polynucleotides.
Also provided are diagnostic methods for detecting diseases, disorders and conditions associated with the polypeptides and polynucleotides, and therapeutic methods for treating such disorders and conditions. The invention further relates to screening methods for identifying binding partners of this polypeptide.

DETAILED DESCRIPTION Definitions The following definitions are provided to facilitate understanding of certain terms used throughout this specification.

In the present invention, “isolated” refers to a substance taken from its original environment (eg, the natural environment if it is naturally occurring), and thus It has been altered "by the hand of man" from its natural state. For example, an isolated polynucleotide can be part of a vector or composition, or contained within a cell, and is still "isolated." This is because the vector, composition, or particular cell is not the natural environment for the polynucleotide. The term "isolated" includes genomic or cDNA libraries, whole whole cell or mRNA preparations, genomic DNA preparations (including those separated by electrophoresis and transferred to a blot), No reference is made to sheared whole cell genomic DNA preparations or other compositions which the art does not exhibit the distinguishing characteristics of the polynucleotides / sequences of the invention.

In the present invention, “secreted” proteins are proteins that can be directed as a result of a signal sequence in the ER, secretory vesicles, or extracellular space, as well as those that do not necessarily contain a signal sequence but are released into the extracellular space. Refers to protein. If a secreted protein is released into the extracellular space, it may undergo extracellular processing to produce a "mature" protein. Release into the extracellular space can occur by many mechanisms, including exocytosis and proteolytic cleavage.

[0010] In certain embodiments, the polynucleotide of the invention is at least 15, at least 30, at least 50, at least 100, at least 125, at least 500 or at least 1000 contiguous nucleotides, but 300 kb, 200 kb in length. , 100 kb, 50 kb, 15 kb, 10 kb, 7.5
kb, 5 kb, 2.5 kb, 2.0 kb or 1 kb or less. In a further embodiment, the polynucleotide of the invention, as disclosed herein, comprises part of the coding sequence but not all or part of any intron.
In another embodiment, the polynucleotide comprising the coding sequence does not include the coding sequence of a genomic flanking gene (ie, 5'or 3'to the gene of interest in the genome). In another embodiment, the polynucleotide of the invention has 100
0, 500, 250, 100, 50, 25, 20, 15, 10, 5, 4, 3, 2
, Or no more than one genomic flanking gene coding sequence.

As used herein, “polynucleotide” refers to SEQ ID NO: X (SE
Q ID NO: X) refers to a molecule having the nucleic acid sequence contained in it or a cDNA contained in a clone deposited with the ATCC. For example, the polynucleotide includes 5'and 3'untranslated sequences, a coding region with or without a signal sequence, a nucleotide sequence of a full-length cDNA sequence containing a secretory protein coding region, and fragments, epitopes, domains of this nucleic acid sequence. , And variants. Further, as used herein, "polypeptide", as broadly defined, refers to a molecule having a translated amino acid sequence derived from a polynucleotide.

In the present invention, the full length sequence identified as SEQ ID NO: X was often generated by duplicating sequences contained in multiple clones (contig analysis).
A representative clone containing all or most of the sequence for SEQ ID NO: X has been deposited with the American Type Culture Collection ("ATCC"). As shown in Table 1, each clone is identified by its cDNA clone ID (identifier) and ATCC Deposit Number. ATCC is 10801 University B
ulevard, Manassas, Virginia 20110-220.
Located in 9, USA. The ATCC deposit was made in accordance with the provisions of the Budapest Treaty on the International Recognition of the Deposit of Microorganisms for Patent Prosecution Purposes.

The “polynucleotide” of the invention also hybridizes under stringent hybridization conditions to the sequence contained in SEQ ID NO: X, its complement, or the cDNA contained in the clone deposited with the ATCC. The resulting polynucleotide is included. “Stringent hybridization conditions” means 50% formamide, 5 × SSC (750 mM NaCl, 75 mM trisodium citrate), 50 mM sodium phosphate (pH 7.6), 5 × Denhardt's solution, 10%
Refers to overnight incubation at 42 ° C. in a solution containing dextran sulfate and 20 μg / ml denatured sheared salmon sperm DNA, followed by washing filters in 0.1 × SSC at about 65 ° C.

Nucleic acid molecules that hybridize to the polynucleotides of the invention at lower stringency hybridization conditions are also contemplated. Changes in hybridization stringency and signal detection are primarily achieved through manipulation of formamide concentrations (lower percentages of formamide produce reduced stringency); salt conditions, or temperature. For example, lower stringency conditions are 6 × SSPE (20 × SSPE = 3M NaCl;
2M NaH ₂ PO ₄ ; 0.02M EDTA, pH 7.4), 0.5% SDS
, 30% formamide, 100 μg / ml salmon sperm blocking DNA, incubated overnight at 37 ° C .; then 1 × SSPE, 0.1% S
Includes washing with DS at 50 ° C. Furthermore, in order to achieve even lower stringency, the washes performed after stringent hybridization can be performed at higher salt concentrations (eg 5 × SSC).

Note that the changes in the above conditions can be achieved by the inclusion and / or substitution of alternative blocking reagents used to suppress background in hybridization experiments. Representative blocking reagents include Denhardt's reagent, BLOTTO, heparin, denatured salmon sperm DNA, and commercially available proprietary formulations. The inclusion of specific blocking reagents may require modification of the above hybridization conditions due to compatibility issues.

Of course, a poly A + sequence (eg, any 3 ′ end poly A + region of the cDNA shown in the sequence listing) or a poly hybridizing only to a complementary stretch of T (or U) residues. Nucleotides are not included in the definition of "polynucleotide." Because such a polynucleotide hybridizes to any nucleic acid molecule containing a poly (A) stretch or its complement (eg, virtually any double-stranded cDNA clone generated using oligo dT as a primer). Because it soybeans.

“SEQ ID NO: X (SEQ ID NO: X)” refers to a polynucleotide sequence, while “SEQ ID NO: Y (SEQ ID NO: Y)” refers to a polypeptide sequence, both sequences being , Identified by the integers specified in Table 1.

A “polypeptide having biological activity” refers to a polypeptide of the invention (mature form (Including), but not necessarily the same. If a dose dependence is present, it need not be identical to that of this polypeptide, but rather is substantially similar to that of a given activity when compared to a polypeptide of the invention ( That is, the candidate polypeptide is

More, and preferably about 1/10 or more of activity, and most preferably about 1/3
The above activity is shown).

Many proteins (and translated DNA sequences) contain regions whose amino acid composition is highly offset to a small subset of available residues. For example, the transmembrane domain and signal peptide, which is also transmembrane, are typically
Includes long stretches dominated by leucine (L), valine (V), alanine (A), and isoleucine (I). The polyadenosine region at the end of the cDNA (poly A
) Appears as polylysine (poly-K) in forward translation, and polyphenylalanine (poly-F) when the reverse complement is translated. These areas are often referred to as "lower complexity" areas.

Such regions may allow a database similarity search program such as BLAST to find high scoring sequence matches that do not imply true homology. Most weight matrices (used to score alignments produced by BLAST) are commonly found in groups of hydrophobic amino acids (L, V and I) found in certain low complexity regions. To a match between either,
The problem is exacerbated by the fact that it gives high scores almost as well as high scores for exact matches.

To correct this, BLASTX. 2 (Version 2.0a5MP-

) ”Using two filters (“ seg ”and“ xnu ”). These filters analyze the sequences for such regions and create new sequences in which amino acids in the lower complexity regions are replaced by the letter "X". This is then the input sequence to the BLASTX program (sometimes referred to herein as "
"Query" and / or "Q"). This regimen helps ensure that high-scoring matches represent true homology, while negative consequences in that the BLASTX program uses a query sequence masked by a filter to draw the alignment. Exists.

[0024] Thus, the stretch of "X" in the alignment shown in the following application does not necessarily indicate that either the underlined DNA sequence or the translated protein sequence is unknown or unspecified. And also the presence of such a stretch is not meant to indicate that this sequence is or is not identical to the sequences disclosed in the alignment of the present invention. Such a stretch is defined by the BLASTX program as defined above.
Due to the detection of regions of low complexity, it may simply be shown to mask the amino acids in that region. In all cases, the specification, sequence listing (Table 1), and / or
Alternatively, the reference sequence shown in the deposited clone (sometimes referred to herein as “Subject”, “Sbjct”, and / or “S”) is critical to the practice of the invention. It should not be construed as limiting the invention to the partial sequences shown in the alignment, unless it is in the form and is shown in detail elsewhere in the specification.

[Table 1] Table 1 summarizes the information corresponding to each "gene number" above. The nucleotide sequence identified as "nucleotide sequence number X" is identified in Table 1 as "
cDNA clone ID ", and in some cases, partially homologous (" overlapping ") sequences from additional related DNA clones. Overlapping sequences were assembled into a single highly contiguous contiguous sequence (usually 3-5 overlapping sequences at each nucleotide site), yielding the final sequence identified as SEQ ID NO: X.

The cDNA clone ID was deposited on that date and is labeled "ATCC Deposit No. Z.
And the corresponding accession numbers listed under "Dates". Some of the deposits contain multiple different clones corresponding to the same gene. "Vector" refers to the type of vector contained in the cDNA clone ID.

“Total nucleotide sequence” refers to the total number of nucleotides in the contig identified by the “gene number”. The deposited clone may contain all or most of these sequences, which are reflected by the nucleotide positions shown as "5 'nucleotides of the clone sequence" and "3' nucleotides of the clone sequence" in SEQ ID NO: X. It The nucleotide position of SEQ ID NO: X of the putative start codon (methionine) is identified as the "5 'nucleotide of the start codon". Similarly, the nucleotide position of SEQ ID NO: X of the putative signal sequence is identified as "the 5'nucleotide of the first amino acid of the signal peptide".

The translated amino acid sequence begins with methionine and is identified as "amino acid sequence number Y", although other reading frames can also be readily translated using known molecular biology techniques. Polypeptides produced by these alternative open reading frames are specifically contemplated by the present invention.

The positions of the first and last amino acids of the putative signal peptide SEQ ID NO:
It is identified as "the first amino acid of the signal peptide" and "the last amino acid of the signal peptide". The position of the deduced first amino acid of SEQ ID NO: Y of the secretory portion is identified as the “deduced first amino acid of the secretory portion”. Finally, the amino acid position of SEQ ID NO: Y of the last amino acid in the open reading frame is identified as the "last amino acid of the ORF."

SEQ ID NO: X (where X can be any polynucleotide sequence disclosed in the sequence listing) and translated SEQ ID NO: Y (where Y is any polypeptide disclosed in the sequence listing). Sequence) may be sufficiently accurate and otherwise suitable for various applications well known in the art and as further described below. For example, SEQ ID NO: X is useful for designing a nucleic acid hybridization probe that detects the nucleic acid sequence contained in SEQ ID NO: X or the cDNA contained in the deposited clone. These probes also hybridize to nucleic acid molecules in biological samples, thereby enabling the various forensic and diagnostic methods of the invention. Similarly, the polypeptides identified from SEQ ID NO: Y are used, for example, to make antibodies that specifically bind to the proteins (including polypeptides and secreted proteins) encoded by the cDNA clones identified in Table 1. Can be used for.

Nevertheless, the DNA sequences produced by the sequencing reaction may contain sequencing errors. This error, as a misidentified nucleotide,
Or as a nucleotide insertion or deletion in the generated DNA sequence. Incorrectly inserted or deleted nucleotides cause a frameshift in the reading frame of the deduced amino acid sequence. In these cases, even though the DNA sequence produced may be more than 99.9% identical to the actual DNA sequence (eg, a single base insertion or deletion in an open reading frame greater than 1000 bases), The deduced amino acid sequence differs from the actual amino acid sequence.

Therefore, for those applications requiring accuracy in the nucleotide or amino acid sequence, the present invention provides a generated nucleotide sequence identified as SEQ ID NO: X and a putative nucleotide sequence identified as SEQ ID NO: Y. Also provided is a sample of plasmid DNA containing the human cDNA of the invention deposited at the ATCC, as described in Table 1, as well as the translated amino acid sequence of The nucleotide sequence of each deposited clone can be readily determined by sequencing the deposited clone according to known methods. Then the deduced amino acid sequence is
It can be evidenced from such deposits. In addition, the amino acid sequence of the protein encoded by a particular clone may also be expressed by peptide sequencing or in a suitable host cell containing the deposited human cDNA, the protein collected, and the sequence determined. By determining, it can be determined directly.

The invention also relates to the gene corresponding to SEQ ID NO: X, SEQ ID NO: Y, or the deposited clone.

It is often advantageous to include additional amino acid sequences including secretory or leader sequences, prosequences, sequences that aid in purification (eg, multiple histidine residues), or additional sequences for stability during recombinant production.

There is provided a polypeptide comprising or consisting of a polypeptide encoded by the cDNA contained therein. Polynucleotide sequences comprising or consisting of the polypeptide sequence of SEQ ID NO: and / or the cDNA sequence encoded by the cDNA contained in ATCC Deposit Z are also encompassed by the invention. .

Signal Sequence The present invention also includes the mature form of the polypeptide having the polypeptide sequence of SEQ ID NO: and / or the polypeptide sequence encoded by the cDNA in the deposited clone. Also included in the invention is a polynucleotide encoding the mature form (eg, such as the polynucleotide sequence of SEQ ID NO: X, and / or the polynucleotide sequence contained in the cDNA of the deposited clone). According to the signal hypothesis, once the transport of a growing protein chain across the rough endoplasmic reticulum is initiated, the protein secreted by mammalian cells may contain a signal sequence or secretory leader sequence that is cleaved from the mature protein. Have. Even most mammalian and insect cells cleave secreted proteins with the same specificity. However, in some cases, cleavage of the secreted protein is not completely uniform, which results in more than one mature species of this protein. Furthermore, it has long been known that the cleavage specificity of secreted proteins is ultimately determined by the primary structure of the intact protein (ie, it is unique to the amino acid sequence of this polypeptide).

Methods are available for predicting whether a protein has a signal sequence, as well as a breakpoint for that sequence. For example, McGeoch, Vi
rus Res. 3: 271-286 (1985) uses information from a short N-terminal charged region followed by an uncharged region of the intact (uncleaved) protein. von Heinje, Nucleic Acids Res
． 14: 4683-4690 (1986) uses information from the residues surrounding the cleavage site (typically -13 to +2 residues), where +1 indicates the amino terminus of the secreted protein. . The accuracy of predicting breakpoints of known mammalian secretory proteins for each of these methods is in the range of 75-80% (
von Heinje, supra). However, the two methods do not always produce the same putative breakpoint for a given protein.

In the present case, the deduced amino acid sequence of the secreted polypeptide is Si
A computer program called gnalP (Henrik Nielse

Analyzed by This program predicts the location of proteins in cells based on their amino acid sequences. As part of the computer prediction of this localization, Mc
The method of Geoch and von Heinje is incorporated. Analysis of the amino acid sequences of the secreted proteins described herein by this program is shown in Table 1.
Provided the results shown in.

However, as will be appreciated by one of skill in the art, the cleavage site will occasionally vary from organism to organism and cannot be predicted with absolute certainty. Thus, the invention provides a secreted polypeptide having the sequence set forth in SEQ ID NO: Y, which has an N-terminus beginning within 5 residues of the putative breakpoint (ie, + or -5 residues). Have.
Similarly, it is also recognized that, in some cases, cleavage of the signal sequence from the secreted protein is not globally uniform, resulting in more than one secreted species. These polypeptides and polynucleotides encoding such polypeptides are contemplated by the present invention.

Furthermore, the signal sequences identified by the above analysis may not necessarily predict the naturally occurring signal sequence. For example, the naturally occurring signal sequence can be further upstream from the putative signal sequence. However, the putative signal sequence likely directs the secreted protein to the ER. Nonetheless, the present invention produces by expression in mammalian cells (eg, COS cells as described above) the polynucleotide sequence of SEQ ID NO: X and / or the polynucleotide sequence contained in the cDNA of the deposited clone. A mature protein that is These polypeptides, and the polynucleotides encoding such polypeptides,
Contemplated by the present invention.

(Polynucleotide and Polypeptide Variants) The present invention relates to variants of the polynucleotide sequence disclosed in SEQ ID NO: X, its complementary strand, and / or the cDNA sequence contained in the deposited clone. .

The present invention also includes variants of the polypeptide sequences disclosed in SEQ ID NO: Y and / or the polypeptide sequences encoded by the deposited clones.

“Variant” refers to a polynucleotide or polypeptide that differs from the polynucleotide or polypeptide of the invention but retains their essential properties. In general, variants are wholly closely similar and, in many regions, identical to the polynucleotides or polypeptides of the invention.

The invention also encodes, for example, the sequence encoding the nucleotide of SEQ ID NO: X or its complementary strand, the sequence encoding the nucleotide contained in the deposited cDNA clone or its complementary strand, the polypeptide of SEQ ID NO: Y. Nucleotide sequence encoding the polypeptide encoded by the cDNA contained in the deposited clone, and / or a polynucleotide fragment of any of these nucleic acid molecules (eg, the fragments described herein). ), At least 80%, 85%, 90%, 95%, 96%, 97%, 98%
, Or 99% identical to or consisting of a nucleotide sequence. Polynucleotides that hybridize to these nucleic acid molecules under stringent hybridization conditions or less stringent conditions, polypeptides encoded by these polynucleotides are also encompassed by the invention.

The present invention also includes, for example, the polypeptide sequence set forth in SEQ ID NO: Y, the polypeptide sequence encoded by the cDNA contained in the deposited clone, and / or
Or a polypeptide fragment of any of these polypeptides (eg,
At least 80%, 85%, relative to the fragments described herein)
It relates to polypeptides which comprise or consist of amino acid sequences which are 90%, 95%, 96%, 97%, 98%, 99% identical.

By a nucleic acid having a nucleotide sequence that is at least 95% “identical” to a reference nucleotide sequence of the present invention, the nucleotide sequence of the nucleic acid is 100 nucleotides each of the reference nucleotide sequence, the nucleotide sequence encoding a polypeptide. It is intended to be identical to a reference sequence, except that up to 5 point mutations can be included. In other words, at least 9 relative to the reference nucleotide sequence
Up to 5% of the nucleotides of the reference sequence can be deleted or replaced by another nucleotide in order to obtain a nucleic acid having a nucleotide sequence of 5% identity,
Alternatively, a large number of nucleotides, up to 5% of the total nucleotides in the reference sequence, can be inserted in the reference sequence. The query sequence can be the entire sequence shown in Table 1, the ORF (open reading frame), or any fragment identified as described herein.

As a practical matter, any particular nucleic acid molecule or polypeptide will be at least 80%, 85%, 90%, 95%, 96%, 9% of the nucleotide sequences of the invention.
Whether 7%, 98%, or 99% identical can be conventionally determined using known computer programs. A preferred method for determining the best overall compatibility (also referred to as global sequence alignment) between a query sequence (sequence of the invention) and a subject sequence is described by Brutlag et al. (Comp. App
． Biosci. 6: 237-245 (1990)) based on the FASTDB computer program. In a sequence alignment, both the query and subject sequences are DNA sequences. RNA
Sequences can be compared by converting U to T. The results of this global sequence alignment are expressed as percent identity (%). Preferred parameters used in the FASTDB alignment of DNA sequences to calculate percent identity are: Matrix = Unitary, k-tuple = 4, Mismatch P.
energy = 1, Joining Penalty = 30, Randomiz
ation Group Length = 0, Cutoff Score = 1,
Gap Penalty = 5, Gap Size Penalty 0.05,
Windows Size = 500 or the length of the nucleotide sequence of interest (whichever is shorter).

If the subject sequence is shorter than the query sequence due to 5'or 3'deletions (as opposed to internal deletions), manual corrections must be made to the results. This is because the FASTDB program does not consider 5'and 3'truncations of the subject sequence when calculating percent identity. For a subject sequence that is cleaved at the 5'or 3'end, the percent identity to the query sequence is the 5'and 3'of the subject sequence that is not matched / aligned as a percentage of the total bases of the query sequence. Corrected by calculating the number of bases in. Whether the nucleotides are matched / aligned is determined by the results of the FASTDB sequence alignment. This percentage is then subtracted from the percent identity and calculated by the FASTDB program above using the specified parameters to arrive at the final percent identity score. This corrected score is what is used for the purposes of the present invention. Only the bases outside the 5'and 3'bases of the subject sequence that are not matched / aligned with the query sequence, as indicated by the FASTDB alignment, are calculated for the purpose of manually adjusting the percent identity score.

For example, a 90 base subject sequence is aligned with a 100 base query sequence to determine percent identity. The deletion occurs at the 5'end of the subject sequence, so the FASTDB alignment shows no match / alignment at the first 10 bases at the 5'end. 1
0 unpaired bases represent 10% of the sequence (number of bases at the non-matching 5'and 3'ends / total number of bases in the query sequence), so 10% is FASTD
Subtracted from the percent identity score calculated by the B program.
If the remaining 90 bases were an exact match, the final percent identity would be 90%. In another example, a 90 base subject sequence is compared to a 100 base query sequence. In this case, the deletion is an internal deletion, so that there are no bases at the 5'or 3'of the subject sequence that are not matched / aligned with the query. In this case, FASTD
The percent identity calculated by B is not manually corrected. Again, only the 5'or 3'bases of the subject sequence that do not match / align with the query sequence are manually corrected. No other manual correction is made for the purposes of the present invention.

An amino acid sequence of a subject polypeptide may be a polypeptide having an amino acid sequence that is at least 95% “identical” to the query amino acid sequence of the invention, such that It is intended to be identical to the query sequence, except that changes of up to 5 amino acids per 100 amino acids may be included. In other words, up to 5% of the amino acid residues in the sequence of interest are inserted, deleted, (indels) in order to obtain a polypeptide having an amino acid sequence that is at least 95% identical to the query amino acid sequence.
Or it may be replaced by another amino acid. These modifications of the reference sequence can occur at the amino-terminal or carboxy-terminal positions of the reference amino acid sequence, or anywhere between those terminal positions, either individually between the residues in the reference sequence or the reference sequence. Interspersed in any one or more of the consecutive groups within.

As a practical matter, any particular polypeptide may be used, for example, for the amino acid sequence shown in Table 1 (SEQ ID NO: Y) or for the cDNA contained in the deposited clone.
At least 80%, 85%, 9 for the amino acid sequence encoded by A
Whether 0%, 95%, 96%, 97%, 98%, or 99% identical can be determined conventionally using known computer programs. A preferred method for determining the best global match (also referred to as global sequence alignment) between a query sequence (the sequence of the invention) and a subject sequence is described by Brutlag et al.
Comp. App. Biosci. 6: 237-245 (1990)) based on the FASTDB computer program. In a sequence alignment, the query and subject sequences are either both nucleotide sequences or both amino acid sequences. The results of the above global sequence alignments are given in percent identity. The preferred parameters used for FASTDB amino acid alignment are: Matrix = PAM 0, k-tu.
ple = 2, Mismatch Penalty = 1, Joining Pen
alty = 20, Randomization Group Length = 0
, Cutoff Score = 1, Window Size = length of array,
Gap Penalty = 5, Gap Size Penalty = 0.0
5, Windows Size = 500 or the length of the target amino acid sequence (whichever is shorter).

If the sequence of interest is shorter than the query sequence due to N-terminal or C-terminal deletions (as opposed to internal deletions), manual corrections must be made to the results. This is because the FASTDB program does not consider N-terminal and C-terminal truncations of the subject sequence when calculating the overall percent identity. Regarding the target sequence shortened at the N-terminus and C-terminus, with respect to the query sequence,
Percent identity is corrected by calculating the number of residues in the query sequence that are N- and C-terminal to the subject sequence that are not matched / aligned with the corresponding subject residues as a percentage of the total bases of the query sequence. . Whether the residues are matched / aligned is determined by the results of the FASTDB sequence alignment. This percentage is then subtracted from the percent identity and calculated by the FASTDB program above using specific parameters to arrive at the final percent identity score. This final percent identity score is what is used for the purposes of the present invention. Only those residues N- and C-terminal to the subject sequence that are not matched / aligned with the query sequence are considered for the purpose of manually adjusting the percent identity score. That is, only the query residue is the furthest N in the subject sequence.
Located outside the terminal and C-terminal residues.

For example, a 90 amino acid residue subject sequence is aligned with a 100 residue query sequence to determine percent identity. Deletions occur at the N-terminus of the subject sequence, and therefore the FASTDB alignment does not show a match / alignment of the first 10 residues at the N-terminus. The 10 unpaired residues represent 10% of the sequence (mismatched N-terminus and C
Represents the number of residues at the end / total number of residues in the query sequence, and the result is FAST
10% is subtracted from the percent identity score calculated by the DB program. If the remaining 90 residues were perfectly matched, the final percent identity would be 90%. In another example, a 90 residue subject sequence is compared to a 100 residue query sequence. In this case, the deletion is an internal deletion, so there are no residues at the N-terminus or C-terminus of the subject sequence that are not matched / aligned with the query sequence. In this case, the percent identity calculated by FASTDB is not manually corrected. Again, only residue positions outside the N- and C-termini of the subject sequence that do not match / align with the query sequence, as shown in the FASTDB alignment, are manually corrected.
No other manual correction is made for the purposes of the present invention.

Variants may include changes in the coding regions, non-coding regions, or both. Especially preferred are those that produce silent substitutions, additions or deletions,
Polynucleotide variants containing changes that do not alter the properties or activity of the encoded polypeptide. Nucleotide variants produced by silent substitutions due to the degeneracy of the genetic code are preferred. Furthermore, 5 in any combination
Variants in which -10, 1-5, or 1-2 amino acids are substituted, deleted, or added are also preferred. Polynucleotide variants optimize codon expression for a variety of reasons (eg, codon expression for a particular host (codons in human mRNA are described in E.
for a preferred codon by a bacterial host such as E. coli)),
Can be generated.

Naturally occurring variants are referred to as “allelic variants” and refer to one of several alternative forms of a gene that occupy a given locus on the chromosome of an organism. (Genes II, Lewin, B., edited by John Wiley &
Sons, New York (1985)). These allelic variants are
It can vary at either the polynucleotide level and / or the polypeptide level and is included in the present invention. Alternatively, non-naturally occurring variants may be produced by mutagenesis techniques or by direct synthesis.

Using known methods of protein engineering and recombinant DNA technology, variants are
It can be made to improve or change the properties of the polypeptides of the invention. For example, one or more amino acids can be deleted from the N-terminus or C-terminus of the secreted protein without substantial loss of biological function. Ron et al. Biol. Ch
em. 268: 2984-2988 (1993) authors 3, 8, or 2
A modified KGF protein was reported that had heparin binding activity even after deletion of the 7 amino terminal amino acid residues. Similarly, interferon-gamma, after deleting 8-10 amino acid residues from the carboxy terminus of this protein,
It showed higher activity up to 0-fold (Dobeli et al., J. Biotechnol.
7: 199-216 (1988)).

In addition, a wealth of evidence demonstrates that variants often retain activities similar to those of naturally occurring proteins. For example, Gayle and co-workers (J. Biol. Chem 268: 22105-22111 (1
993)) performed an extensive mutational analysis of the human cytokine IL-1a. They used random mutagenesis to generate over 3,500 individual IL-1a variants that averaged 2.5 amino acid changes per variant over the entire length of the molecule. Multiple mutations were tested at every potential amino acid position. The investigators found that "the majority of molecules can be altered with little effect on either [binding activity or biological activity]." (See summary). In fact, of the over 3,500 nucleotide sequences tested,
Only 23 unique amino acid sequences produced proteins that differed significantly in activity from the wild type.

In addition, deletion of one or more amino acids from the N-terminus or C-terminus of a polypeptide may result in modification or deletion of one or more biological functions, but not other biological functions. Activity can still be retained. For example, the ability of a deletion variant to induce and / or bind an antibody that recognizes a secreted form is the ability to remove less than the majority of the secreted form from the N-terminus or C-terminus. Seems to be retained. Whether a particular polypeptide lacking the N-terminal or C-terminal residues of a protein retains such immunogenic activity depends on conventional methods described herein, and so on. If not, it can be easily determined by a conventional method known in the art.

Accordingly, the present invention further includes polypeptide variants that exhibit substantial biological activity. Such variants include deletions, insertions, inversions, repeats, and substitutions selected according to general rules known in the art such that they have little effect on activity. For example, guidance on how to make phenotypically silent amino acid substitutions can be found in Bowie et al., Science 247: 1.
306-1310 (1990), where the authors point out that there are two main strategies for studying the tolerance of amino acid sequences to changes.

The first strategy exploits the tolerance of amino acid substitutions by natural selection during the course of evolution. Conserved amino acids can be identified by comparing amino acid sequences in different species. These conserved amino acids appear to be important for protein function. In contrast, the amino acid positions at which the substitutions were tolerated by natural selection indicate that these positions are not important for protein function. Thus, the positions that tolerate amino acid substitutions may be modified, yet still maintain the biological activity of the protein.

The second strategy uses genetic engineering to introduce amino acid changes at specific positions in the cloned gene to identify regions important for protein function. For example, site-directed mutagenesis or alanine scanning mutagenesis (
The introduction of one alanine mutation at each residue in the molecule) can be used. (Cuni
ngham and Wells, Science 244: 1081-1085 (
1989)). The resulting mutant molecule can then be tested for biological activity.

As the authors note, these two strategies have revealed that the protein is surprisingly tolerant of amino acid substitutions. The authors further indicate which amino acid changes are likely to be tolerated at particular amino acid positions in the protein. For example, amino acid residues that are mostly buried (within the tertiary structure of the protein) require non-polar side chains, but surface side chain characteristics are generally poorly conserved. In addition, tolerant conservative amino acid substitutions include the substitution of aliphatic or hydrophobic amino acids Ala, Val, Leu, and Ile; the substitution of Ser and Thr for hydroxyl residues; the substitution of Asp and Glu for acidic residues; Amide residue Asn
And Gln, basic residues Lys, Arg, and His; aromatic residues Phe, Tyr, and Trp, and small-sized amino acids Ala, Ser, Thr, Met, and Gly. Including replacement.

In addition to conservative amino acid substitutions, variants of the invention include (i) substitution with one or more non-conservative amino acid residues, where the amino acid residue replaced is by the genetic code. It may or may not be the encoded amino acid residue, or (ii) substitution with one or more amino acid residues having a substituent, or (i
ii) fusion of the mature polypeptide with another compound (eg, a compound to increase the stability and / or solubility of the polypeptide (eg, polyethylene glycol)), or (iv) an additional amino acid (eg, IgG). Fc fusion region peptides, or fusions of polypeptides with leader or secretory sequences, or sequences which facilitate purification). Such variant polypeptides are considered to be within the skill of those in the art given the teachings herein.

[0200] For example, polypeptide variants comprising amino acid substitutions of charged amino acids with other charged amino acids or neutral amino acids have proteins with improved properties (eg, less aggregation). Can be generated. Aggregation of pharmaceutical formulations results in both reduced activity and increased clearance due to the immunogenic activity of the aggregate. (Pinckard et al., Clin. Exp. Immunol. 2: 331.

Polypeptide fragments of SEQ ID NO: Y contained within the conserved domain are specifically contemplated by the present invention. In addition, polynucleotides encoding these domains are also contemplated.

Other preferred polypeptide fragments are biologically active fragments. A biologically active fragment is a fragment that exhibits similar activity but is not necessarily identical to that of the polypeptide of the invention. The biological activity of this fragment may include improved desired activity or reduced undesired activity. Polynucleotides encoding these polypeptide fragments are also

The term “epitope” as used herein refers to that portion of a polypeptide that has antigenic or immunogenic activity in an animal, preferably a mammal, and most preferably a human. In a preferred embodiment, the invention includes a polypeptide that comprises an epitope as well as a polynucleotide that encodes this polypeptide. As used herein, an "immunogenic epitope" is defined as the portion of a protein that elicits an antibody response in an animal and can be any method known in the art (e.g., antibody production as described below). Method). (For example, Geysen et al., Proc. Natl. Acad. Sci. USA 81: 3.
998-4002 (1983)). As used herein,
The term "antigenic epitope" refers to a protein by which an antibody can immunospecifically bind to its antigen as measured by any method known in the art (eg, immunoassays described herein). Is defined as part of. Immunospecific binding excludes non-specific binding but does not necessarily exclude cross-reactivity with other antigens. Antigenic epitopes do not necessarily require immunogenicity.

Fragments that function as epitopes can be generated by any conventional means. (For example, Houghten, Proc. Natl. Acad. Sci.
USA 82: 5131-5135 (1985) (U.S. Pat. No. 4,631,21).

In the present invention, the antigenic epitope is preferably at least 4, at least 5, at least 6, at least 7, more preferably at least 8,
At least 9, at least 10, at least 11, at least 12, at least 13, at least 14, at least 15, at least 20, at least 25, at least 30, at least 40, at least 50, and most It preferably comprises a sequence of between about 15 and about 30 amino acids. Preferred polypeptides are at least 10, 15, 20, 25, 30, 35, 40, 45,

It includes immunogenic or antigenic epitopes of amino acid residue length. Additional non-exclusive preferred antigenic epitopes include the antigenic epitopes disclosed herein, as well as portions thereof. Antigenic epitopes are useful, for example, to raise antibodies (including monoclonal antibodies) that specifically bind to this epitope. Preferred antigenic epitopes include the antigenic epitopes disclosed herein, as well as any combination of two, three, four, five or more of these antigenic epitopes. Antigenic epitopes can be used as target molecules in immunoassays. (For example, Wilson et al., Cell 37: 767-778 (19
84); Sutcliffe et al., Science 219: 660-666 (1).
983)).

Similarly, immunogenic epitopes can be used to induce antibodies, eg, according to methods well known in the art. (For example, Sutcliffe et al. (Supra); Wils
on et al. (supra); Chow et al., Proc. Natl. Acad. Sci. USA
82: 910-914; and Bittle et al., J. Am. Gen. Virol. 6
6: 2347-2354 (1985)). Preferred immunogenic epitopes include the immunogenic epitopes disclosed herein, as well as any combination of two, three, four, five or more of these immunogenic epitopes. A polypeptide comprising one or more immunogenic epitopes may be presented to elicit an antibody response against an animal system (eg rabbit or mouse) with a carrier protein (eg albumin), or the polypeptide may be If sufficiently long (at least about 25 amino acids), the polypeptide can be presented without a carrier. However, immunogenic epitopes containing as few as 8-10 amino acids
It has been shown to be sufficient (e.g. in Western blotting) to raise antibodies capable of (at least) binding to the linear epitope of the denatured polypeptide.

The epitope-bearing polypeptides of the present invention can be used to induce antibodies according to methods well known in the art. This method includes, but is not limited to, in vivo immunization, in vitro immunization, and phage display methods.
For example, Sutcliffe et al., Supra; Wilson et al., Supra; and Bitt.
le et al. Gen. Virol. , 66: 2347-2354 (1985). When in vivo immunization is used, animals can be immunized with free peptides; however, anti-peptide antibody titers are dependent on the macromolecule carrier (eg, keyhole limpet hemacyanin (KLH) or tetanus toxoid) peptide. Can be boosted by combining. For example, peptides containing cysteine residues can be linked to carriers using linkers such as maleimidobenzoyl-N-hydroxysuccinimide ester (MBS). On the other hand, other peptides can be bound to the carrier using more common binding agents such as glutaraldehyde. Animals such as rabbits, rats, and mice use, for example, emulsions (about 100 μg of peptide or carrier protein and Freund's adjuvant or any known to stimulate an immune response) with either free peptide or carrier-bound peptide. Immunization by intraperitoneal injection (including other adjuvants) and / or intradermal injection. Several booster injections may be needed to provide a useful titer of anti-peptide antibody, for example, at intervals of about 2 weeks. This titer can be detected, for example, by an ELISA assay using free peptide adsorbed on the solid surface. Titer of anti-peptide antibody in serum from immunized animals is increased by selection of anti-peptide antibody (eg, by adsorption of peptide on solid support and elution of selected antibody according to methods well known in the art). You can

As will be appreciated by those in the art, and as discussed above, the polypeptides of the present invention that include immunogenic or antigenic epitopes can be fused to other polypeptide sequences. For example, the polypeptides of the present invention are immunoglobulin (Ig
A, IgE, IgG, IgM) constant domains or parts thereof (CH1, C)
H2, CH3, or any combination thereof and portions thereof), resulting in a chimeric polypeptide. Such fusion proteins may facilitate purification and increase half-life in vivo. This has been shown for a chimeric protein consisting of the first two domains of the human CD4-polypeptide and various domains of the constant region of the heavy or light chain of mammalian immunoglobulins. For example, EP 394,827; Traunecker et al., Nature,
331: 84-86 (1988). Enhanced delivery of antigens across the epithelial barrier to the immune system has been demonstrated for antigens bound to FcRn binding partners such as IgG or Fc fragments (eg insulin) (eg PCT Publication WO 96/22024 and (See WO 99/04813). IgG fusion proteins having a disulfide-bonded dimer structure due to disulfide bonds of the IgG moiety are also more effective in binding and neutralizing other molecules than monomeric polypeptides or fragments thereof alone Was found. For example, Fountoulakis et al. Biochem. ，
270: 3958-3964 (1995). Nucleic acids encoding the above epitopes can also be recombined with a gene of interest as an epitope tag (eg, a hemagglutinin (“HA”) tag or a flag tag) for detection and purification of the expressed polypeptide. Can assist. For example, the system described by Janknecht et al. Allows easy purification of non-denatured fusion proteins expressed in human cell lines (Janknecht et al., 1991, Proc. Nat.
l. Acad. Sci. USA 88: 8972-897). In this system,
The gene of interest is subcloned into a vaccinia recombinant plasmid, resulting in
The open reading frame of this gene is translationally fused to an amino-terminal tag consisting of 6 histidine residues. This tag serves as the substrate binding domain for the fusion protein. Extracts from cells infected with recombinant vaccinia virus are loaded onto Ni2 + nitriloacetic acid-agarose columns, and histidine-tagged proteins can be selectively eluted with imidazole-containing buffer.

Further fusion proteins of the invention may be produced through the techniques of gene shuffling, motif shuffling, exon shuffling, and / or codon shuffling (collectively referred to as "DNA shuffling"). D
NA shuffling can be utilized to modulate the activity of the polypeptides of the invention and this method can be used to produce polypeptides with modified activity, as well as agonists and antagonists of these polypeptides. Generally, US Pat. Nos. 5,605,793; 5,811,238; 5,83.

A chimeric antibody is a molecule in which different parts of the antibody are derived from different animal species (for example, an antibody having a variable region derived from a mouse monoclonal antibody and a human immunoglobulin constant region). Methods for producing chimeric antibodies are known in the art. For example, Morris

. A humanized antibody is an antibody molecule from a non-human species antibody that binds to a desired antigen having one or more complementarity determining regions (CDRs) from the non-human species and a framework region from a human immunoglobulin molecule. . Often, framework residues within the human framework regions will be substituted with the corresponding residue from the CDR donor antibody to alter (preferably improve) antigen binding. Substitutions of these frameworks are identified by methods well known in the art, for example modeling CDR and framework residue interactions to identify framework residues important for antigen binding, and at specific positions. By sequence comparison to identify unusual framework residues. (For example, Queen et al., US Pat. No. 5,585,0.

Fully human antibodies are particularly desirable for therapeutic treatment of human patients. Human antibodies can be made by a variety of methods known in the art including phage display methods described above using antibody libraries derived from human immunoglobulin sequences. U.S. Pat.

Human antibodies can also be produced using transgenic mice which are incapable of expressing functional endogenous immunoglobulins but which are capable of expressing human immunoglobulin genes. For example, a complex of human heavy and light chain immunoglobulin genes can be introduced randomly or by homologous recombination into mouse embryonic stem cells. Alternatively, human variable regions, constant regions and diversity regions (diversity)
region) can be introduced into mouse embryonic stem cells in addition to the human heavy chain gene and human light chain gene. The mouse heavy and light chain immunoglobulin genes can be rendered non-functional separately or simultaneously with the introduction of human immunoglobulin loci by homologous recombination. In particular, homozygous deletions in the JH region interfere with endogenous antibody production. The modified embryonic stem cells are expanded and microinjected into blastocysts to produce chimeric mice. Chimeric mice are then bred to produce homozygous offspring that express human antibodies. Transgenic mice are immunized in the normal fashion with a selected antigen (eg, all or part of a polypeptide of the invention). Monoclonal antibodies directed against the antigen can be obtained from immunized transgenic mice using conventional hybridoma technology. The human immunoglobulin transgene carried in the transgenic mouse is B
It reconstitutes during cell differentiation and then undergoes class switching and somatic mutations. Thus, the use of such techniques allows for the production of therapeutically useful IgG, IgA, IgM and IgE antibodies. For an overview of this technology for producing human antibodies, see Lonberg and Huszar,
Int. Rev. Immunol. 13: 65-93 (1995). For a detailed discussion of this technique for producing human antibodies and human monoclonal antibodies, as well as protocols for producing such antibodies, see, eg, PCT Publications WO98 / 24893; WO92 / 01047; WO96 / 340.

The selected non-human monoclonal antibody (eg, mouse antibody) is used to guide the selection of human antibodies that fully recognize the same epitope. (Jespers
Et al., Bio / technology 12: 899-903 (1988)).

Furthermore, antibodies against the polypeptides of the present invention may in turn be utilized to produce anti-idiotypic antibodies that "mimic" the polypeptides of the present invention using techniques well known to those of skill in the art. (Eg Greenspan and Bona, FASEB
J. 7 (5): 437-444; (1989) and Nissinoff, J.

Obtain and, as a result, bind and neutralize the polypeptide and / or its ligand.
Neutralization of such anti-idiotypes or Fab fragments of such anti-idiotypes can be used in therapeutic regimens to neutralize polypeptide ligands. For example, such anti-idiotypic antibodies can be used to bind to a polypeptide of the invention and / or to bind its ligand / receptor, thereby blocking its biological activity.

Polynucleotides Encoding Antibodies The present invention further provides polynucleotides comprising nucleotide sequences encoding the antibodies of the present invention and fragments thereof. The invention also provides an antibody (eg, as defined above) under stringent or less stringent hybridization conditions, preferably which specifically binds to a polypeptide of the invention, preferably , An antibody that binds to a polypeptide having the amino acid sequence of SEQ ID NO: Y).

The polynucleotide may be obtained by any method known in the art and the nucleotide sequence of the polynucleotide determined. For example, if the nucleotide sequence of the antibody is known, the polynucleotide encoding the antibody can be constructed from chemically synthesized oligonucleotides (eg, Kutmeie).
r. et al., BioTechniques 17: 242 (1994)), which briefly includes the following steps: Synthesis of overlapping oligonucleotides containing portions of the sequence encoding the antibody. , Annealing and ligation of these oligonucleotides, followed by amplification of the ligated oligonucleotides by PCR.

Alternatively, antibody-encoding polynucleotides can be generated from nucleic acids from suitable sources. Although clones containing nucleic acid encoding a particular antibody are not available, if the sequence of the antibody molecule is known, the immunoglobulin-encoding nucleic acid can be chemically synthesized or, alternatively, a suitable source ( For example, an antibody cDNA library, or a cDNA library produced from any tissue or cell expressing an antibody (eg, a hybridoma cell selected for expression of an antibody of the invention), or a nucleic acid isolated therefrom. PCR amplification using synthetic primers hybridizable to the 3'and 5'ends of the sequence, for example to identify a cDNA clone from a cDNA library encoding the antibody (preferably poly A + RNA). Or by using an oligonucleotide probe specific for a particular gene sequence. It may be obtained by cloning. P
The amplified nucleic acid produced by CR can then be cloned into a replicable cloning vector using any method known in the art.

Once the antibody nucleotide sequence and corresponding amino acid sequence are determined,
Nucleotide sequences of antibodies may be prepared using methods well known in the art for manipulation of nucleotide sequences (eg, recombinant DNA technology, site-directed mutagenesis, PCR, etc. (eg,

In certain embodiments, the amino acid sequences of the variable domains of the heavy and / or light chains are identified by methods well known in the art for identification of sequences of complementarity determining regions (CDRs) (eg, sequence Other heavy chains to determine hypervariable regions,
And by comparing the variable region of the light chain with a known amino acid sequence). Using conventional recombinant DNA techniques, one or more CDRs may be inserted within the framework regions as described above (eg, into the human framework regions for humanizing non-human antibodies). . The framework regions can be naturally occurring or consensus framework regions, and preferably human framework regions (eg, for the listed human framework regions, Chothia et al., J. Mol. Biol. 278: 457-479 (1
998)). Preferably, the polynucleotide produced by the combination of the framework regions and CDRs encodes an antibody that specifically binds to a polypeptide of the invention. Preferably, as discussed above, one or more amino acid substitutions may be made within the framework regions, and preferably the amino acid substitutions improve the binding of the antibody to its antigen. In addition, such methods may generate antibody molecules lacking one or more intrachain disulfide bonds,
It can be used to make amino acid substitutions or deletions of cysteine residues in one or more variable regions involved in intrachain disulfide bonds. Other changes to the polynucleotide are encompassed by the present invention and in the art.

Furthermore, by splicing a gene derived from a mouse antibody molecule of appropriate antigen specificity with a gene derived from a human antibody molecule of appropriate biological activity, "

As mentioned above, a chimeric antibody is a molecule in which different portions are derived from different animal species, and such molecules have variable regions derived from the constant regions of mouse mAb and human immunoglobulin (eg, humanized antibody). .

Alternatively, described techniques for the production of single chain antibodies (US Pat. No. 4,946,463)

Single chain antibodies are formed by linking the heavy and light chain fragments of the Fv region through amino acid bridges, yielding single chain polypeptides. E. Techniques for the assembly of functional Fv fragments in E. coli can also be used (Sk
erra et al., Science 242: 1038-1041 (1988)).

Methods of Producing Antibodies The antibodies of the invention may be produced by any method known in the art for synthesizing antibodies, in particular by chemical synthesis or, preferably, by recombinant expression techniques. obtain.

The antibodies of the invention, or fragments, derivatives or analogs thereof (eg,
Recombinant expression of a heavy or light chain of an antibody of the invention or a single chain antibody of the invention) requires the construction of an expression vector containing a polynucleotide encoding the antibody. Once the polynucleotide encoding the antibody molecule of the invention or the heavy or light chain of the antibody, or a portion thereof (preferably containing the variable domain of the heavy or light chain) is obtained, production of the antibody molecule Vectors for can be produced by recombinant DNA technology using techniques well known in the art. Accordingly, methods for preparing a protein by expression of a polynucleotide containing a nucleotide sequence encoding an antibody are described herein. Methods well known to those skilled in the art can be used to construct expression vectors containing antibody coding sequences and appropriate transcriptional and translational control signals. These methods include, for example, in vitro recombinant DNA techniques, synthetic techniques, and in vivo genetic recombination. Accordingly, the invention provides a replicable vector comprising a nucleotide sequence encoding an antibody molecule of the invention, or a heavy or light chain thereof, or a heavy or light chain variable domain, operably linked to a promoter. I will provide a.
Such a vector may be a constant region of an antibody molecule (eg PCT Publication WO86 /
05807; PCT Publication WO 89/01036; and US Pat. No. 5,122.
, 464), and the variable domain of the antibody can be cloned into such a vector for total expression of heavy or light chains.

The expression vector is transferred into a host cell by conventional techniques, and the transfected cells are then cultured by conventional techniques to produce the antibody of the invention. Accordingly, the invention includes a host cell containing a polynucleotide encoding an antibody of the invention, or a heavy or light chain thereof, or a single chain antibody of the invention, operably linked to a heterologous promoter. In a preferred embodiment for expression of double-chain antibodies, the vectors encoding both heavy and light chains are co-expressed in a host cell for expression of entire immunoglobulin molecules, as detailed below. Can be done.

A variety of host expression vector systems may be utilized to express the antibody molecule of the present invention. Such host expression systems represent vehicles in which the coding sequence of interest may be produced and subsequently purified, but also in situ when transformed or transfected with sequences encoding the appropriate nucleotides. 2 represents a cell capable of expressing an antibody molecule of the invention. These include, but are not limited to: bacteria transformed with recombinant bacteriophage DNA, plasmid DNA or cosmid DNA expression vectors containing sequences encoding the antibody (eg, E. coli, Microorganisms such as B. subtilis; yeast transformed with recombinant yeast expression vectors containing antibody-encoding sequences (eg, Sacc.
harmomyces, Pichia); insect cell lines infected with a recombinant viral expression vector (eg, baculovirus) containing antibody-encoding sequences; recombinant viral expression vector (eg, cauliflower mosaic virus, CaMV; tobacco mosaic virus, TMV) Or a plant cell line transformed with a recombinant plasmid expression vector (eg, Ti plasmid) containing a sequence encoding an antibody; or a promoter derived from the genome of a mammalian cell (
Mammalian cell lines (eg, COS, CHO, BHK) carrying recombinant expression constructs containing, for example, a metallothionein promoter) or a promoter derived from a mammalian virus (eg, adenovirus late promoter; vaccinia virus 7.5K promoter). 293, 3T3 cells). Preferably Esch
Bacterial cells such as E. coli, and more preferably eukaryotic cells, especially for the expression of whole recombinant antibody molecule, are used for the expression of the recombinant antibody molecule. For example, the major immediate early (ma) derived from human cytomegalovirus.
Chinese hamster ovary cells (C) in combination with a vector such as the jor intermediate early gene promoter element.
Mammalian cells such as HO) are an effective expression system for antibodies (Foec).
King et al., Gene 45: 101 (1986); Cockett et al., Bio.
/ Technology 8: 2 (1990)).

In bacterial systems, a number of expression vectors may be advantageously selected depending on the use intended for the expression of the antibody molecule. For example, if large quantities of such proteins are to be produced, a vector that directs high levels of expression of the easily purified fusion protein product may be desired for the production of pharmaceutical compositions of antibody molecules. Such vectors include, but are not limited to: The antibody-encoding sequence, in frame with the lacZ-encoding region, in the vector.
e) can be separately ligated, so that a fusion protein is produced in E. coli
Expression vector pUR278 (Ruther et al., EMBO J. 2: 1791 (1
983)); pIN vector (Inouye & Inouye, Nucleic
Acids Res. 13: 3101-3109 (1985); Van Hee.
ke & Schuster, J .; Biol. Chem. 24: 5503-5509
(1989)) and so on. The pGEX vector can also be used to express foreign polypeptides as a fusion protein with glutathione S-transferase (GST). In general, such fusion proteins are soluble and can be easily purified from lysed cells by adsorption and binding to matrix glutathione-agarose beads followed by elution in the presence of free glutathione. The pGEX vector is designed to contain a thrombin or factor Xa protease cleavage site so that the cloned target gene product can be released from the GST moiety.

In an insect system, Autographa californica nuclear polyhedrosis virus (AcNPV) is used as a vector to express heterologous genes. This virus grows in Spodoptera frugiperda cells. The antibody coding sequences can be individually cloned into non-essential regions of the virus (eg the polyhedrin gene) and placed under control of the AcNPV promoter (eg the polyhedrin promoter).

In mammalian host cells, a number of virus-based expression systems may be utilized. When an adenovirus is used as an expression vector, the sequence encoding the antibody of interest may be linked to the adenovirus transcription / translation control complex, such as the late promoter and a three-part leader sequence. Then
This chimeric gene can be inserted into the adenovirus genome by in vitro or in vivo recombination. Insertions in nonessential regions of the viral genome (eg, E1 or E3 regions) result in recombinant viruses that are viable and capable of expressing antibody molecules in infected hosts (eg, Logan & Shenk).
, Proc. Natl. Acad. Sci. USA 81: 355-359 (1
984)). Specific initiation signals may also be required for efficient translation of inserted antibody coding sequences. These signals are ATG
It includes a start codon and adjacent sequences. In addition, this initiation codon ensures that translation of the entire insert is ensured by the reading frame of the desired coding sequence (
must be in phase with the reading frame). These exogenous translational control signals and initiation codons can be of various origins, both natural and synthetic. The efficiency of expression can be enhanced by the inclusion of appropriate transcription enhancer elements, transcription terminators, etc. (Bittner et al., Methods in E).
nzymol. 153: 51-544 (1987)).

In addition, a host cell line may be chosen which modulates the expression of the inserted sequences or modifies and processes the gene product in the specific fashion desired.
Such modifications (eg glycosylation) and processing of protein products (
Cleavage, for example) can be important for the function of the protein. Different host cells have characteristic and specific mechanisms for post-translational processing and modification of proteins and gene products. Appropriate cell lines or host systems can be chosen to ensure the correct modification and processing of the foreign protein expressed. To this end, eukaryotic host cells can be used that have the cellular machinery for the precise processing of primary transcription, glycosylation, and phosphorylation of the gene product. Such mammalian host cells include CHO, VERY, BHK, Hela,
COS, MDCK, 293, 3T3, WI38, and especially, for example, BT48
3, breast cancer cell lines such as Hs578T, HTB2, BT20 and T47D, and normal breast cell lines such as, for example, CRL7030 and Hs578Bst.

[0260] Long-term, high-yield production of recombinant proteins and stable expression are preferred. For example, cell lines that stably express the antibody molecule can be engineered. Rather than using an expression vector containing a viral origin of replication, the host cell may choose suitable expression control elements (eg, promoters, enhancers, sequences, transcription terminators, polyadenylation sites, etc.).
, And a DNA controlled by a selectable marker. Heterogeneous DN
Following the introduction of A, the engineered cells can be grown in enriched medium for 1-2 days,
Then, the medium is switched to the selective medium. The selectable marker in the recombinant plasmid confers resistance to selection, and the cell stably integrates the plasmid into its chromosome and proliferates to form cell foci, which in turn can be cloned and propagated. Can become a cell line. This method can be advantageously used to engineer cell lines that express antibody molecules. Such engineered cell lines may be particularly useful in screening and evaluation of compounds that interact directly or indirectly with the antibody molecule.

A number of selection systems may be used, including herpes simplex virus thymidine kinase (Wigler et al., Cell 11: 223 (1977)), hypoxanthine-guanine phosphoribosyl transferase (Szybalska & S.
zybalski, Proc. Natl. Acad. Sci. USA 48: 2

． (See Academic Press, New York, 1987). When the marker in the vector system expressing the antibody is amplifiable, an increase in the level of inhibitor present in the culture of the host cell will increase the number of copies of the marker gene. Since the amplified region is linked to the antibody gene, antibody production is also increased (Crouse et al., Mol. Cell. Biol. 3: 257.
(1983)).

A host cell may be co-transfected with two expression vectors of the invention, a first vector encoding a polypeptide from the heavy chain and a second vector encoding a polypeptide from the light chain. . The two vectors may contain identical selectable markers which enable equal expression of heavy and light chain polypeptides. Alternatively, a single vector may be used, which encodes and expresses both heavy and light chain polypeptides. In such situations, the light chain should be placed before the heavy chain to avoid excess toxic free heavy chain (Pr
audfoot, Nature 322: 52 (1986); Kohler, P.
roc. Natl. Acad. Sci. USA 77: 2197 (1980)).
. The coding sequences for the heavy and light chains may include cDNA or genomic DNA.

Depending on a number of variables, including the type of label used and the mode of administration, the labeled molecule is preferentially concentrated at the site of the subject and is unbound labeled molecule. The time interval after administration is 6 to 48 hours or 6 to 24 hours or 6 to 12 hours, which allows the C. to be cleared to background levels.
In another embodiment, the post-administration time interval is 5-20 days or 5-10 days.

In one embodiment, monitoring a disease or disorder comprises repeating the method for diagnosing the disease or disorder (eg, 1 month after the first diagnosis, 6 months after the first diagnosis, the first diagnosis). 1 year later).

The presence of labeled molecule can be detected from the patient using methods known in the art for in vivo scanning. These methods depend on the type of label used. One of ordinary skill in the art can determine the appropriate method for detecting a particular label. Methods and devices that can be used in the diagnostic methods of the invention include, but are not limited to, computer tomography (CT), whole body scanning such as position emission tomography (PET), magnetic resonance imaging (MRI). , And ultrasonic diagnostic methods.

(Kit) The present invention provides a kit that can be used in the above method. In one embodiment, the kit comprises an antibody of the invention (preferably a purified antibody) in one or more containers. In certain embodiments, the kits of the invention comprise a substantially isolated polypeptide comprising an epitope that is specifically immunoreactive with the antibodies included in the kit. Preferably, the kit of the present invention further comprises a control antibody that does not react with the polypeptide of interest. In another specific embodiment, a kit of the invention provides for the binding of an antibody to a polypeptide of interest (e.g., the antibody has a detectable substrate (e.g., the antibody is a fluorescent compound, an enzyme substrate, a radioactive compound or The second antibody, which may be conjugated to a luminescent compound) or which recognizes the first antibody, may be conjugated to a detectable substrate).

In another particular embodiment of the invention, the kit is for diagnostic use in screening serum containing antibodies specific for proliferative and / or cancerous polynucleotides and polypeptides. It's a kit. Such a kit may include a control antibody that does not react with the polypeptide of interest. Such a kit may comprise a substantially isolated polypeptide antigen that comprises an epitope that is specifically immunoreactive with at least one anti-polypeptide antigen antibody. Further, such kits are for detecting the binding of the antibody to an antigen (eg, the antibody can be conjugated with a fluorescent compound such as fluorescein or rhodamine, which can be detected by flow cytometry). Means are provided. In certain embodiments, the kit may comprise a recombinantly produced polypeptide antigen or a chemically synthesized polypeptide antigen. The polypeptide antigens of this kit can also be attached to a solid support.

In a more particular embodiment, the detection means of the above kit comprises a solid support to which the polypeptide antigen is attached. Such a kit also comprises a non-attached reporter-labeled anti-human antibody. In this embodiment, binding of the antibody to the polypeptide antigen can be detected by binding of the reporter-labeled antibody.

In a further embodiment, the invention comprises a diagnostic kit for use in screening serum containing antigens of the polypeptides of the invention. The diagnostic kit comprises a substantially isolated antibody that is specifically immunoreactive with a polypeptide or polynucleotide antigen, and means for detecting binding of the polynucleotide or polypeptide antigen to the antibody. . In one embodiment, the antibody is

In one diagnostic configuration, test serum is reacted with a solid phase reagent having surface bound antigen obtained by the method of the invention. After binding the specific antigen antibody with this reagent and removing the unbound serum components by washing, in order to bind the reporter with this reagent, depending on the amount of anti-antigen antibody bound on the solid support, This reagent is reacted with a reporter-labeled anti-human antibody. The reagent is washed again to remove unbound labeled antibody and the amount of reporter associated with the reagent is determined. Typically, the reporter is an enzyme detected by incubating this solid phase in the presence of a suitable fluorometric, luminescent or colorimetric substrate (Sigma, St. Louis, MO).

The solid surface reagents in the above assay are used to convert protein material to solid support material (
For example, prepared by known techniques for attachment to polymeric beads, dipsticks, 96-well plates or filtration material). These methods of attachment generally include non-specific adsorption of proteins to the support or chemically active groups (eg, activated carboxyl groups, hydroxyl groups, or aldehyde groups) on the solid support. Covalent attachment of proteins (typically via free amine groups). Alternatively, streptavidin-coated plates can be used with biotinylated antigen.

The invention thus provides an assay system or kit for carrying out this diagnostic method. The kit generally comprises a support having surface-bound recombinant antigens, and a reporter-labeled anti-human antibody for detecting surface-bound anti-antigen antibody.

Fusion Proteins Any polypeptide of the invention can be used to produce a fusion protein. For example, the polypeptides of the present invention can be used as an antigenic tag when fused to a second protein. Antibodies raised against the polypeptides of the invention can be used to indirectly detect a second protein by binding to the polypeptide. Moreover, since secreted proteins target cell locations based on transport signals, the polypeptides of the invention can be used as targeting molecules once fused to other proteins.

Examples of domains that can be fused to the polypeptides of the invention include not only heterologous signal sequences, but also other heterologous functional regions. The fusion does not necessarily have to be direct, but can occur via a linker sequence.

In addition, fusion proteins can also be engineered to improve the characteristics of the polypeptides of the invention. For example, additional amino acids, especially regions of charged amino acids, can be added to the N-terminus of the polypeptide to improve stability and durability during purification from host cells or subsequent handling and storage. Also, peptide moieties may be added to the polypeptide to facilitate purification. Such regions may be removed prior to final preparation of the polypeptide. Addition of peptide moieties to facilitate handling of polypeptides is a conventional technique well known in the art.

Furthermore, the polypeptides (including fragments, and especially epitopes) of the present invention include immunoglobulin (IgA, IgE, IgG, IgM) constant domains or portions thereof (CH1, CH2, CH3, and any thereof). Combination of (
(Including both whole domains and parts thereof)) to give chimeric polypeptides. These fusion proteins facilitate purification and exhibit increased half-life in vivo. One reported example is human CD4
A chimeric protein consisting of the first two domains of the polypeptide and various domains of the constant regions of the heavy or light chains of mammalian immunoglobulins has been described (EP A 394,827; Traunecker et al. Nature 33).
1: 84-86 (1988)). Fusion proteins with disulfide-linked dimeric structures (due to IgG) may also be more efficient at binding and neutralizing other molecules than monomeric secretory proteins or protein fragments alone ( Fountoulakis et al., J. Biochem. 270: 3958.
-3964 (1995)).

Similarly, EP-A-O 464 533 (Canadian counterpart 2045869).
No.) discloses fusion proteins comprising various parts of the constant regions of immunoglobulin molecules together with another human protein or parts thereof. In many cases, the Fc portion of fusion proteins may be beneficial in therapy and diagnosis, thus resulting, for example, in improved pharmacokinetic properties (EP-A 0232 262). Alternatively, it may be desirable to delete the Fc portion after the fusion protein has been expressed, detected and purified. For example, if the fusion protein is used as an antigen for immunization, the Fc portion may interfere with therapy and diagnosis. For example, in drug discovery, human proteins such as hIL-5 have been used for high throughput screening assay purposes to identify antagonists of hIL-5.

ecognition 8: 52-58 (1995); Johnson et al. Biol. Chem. 270: 9459-9471 (1995)).

In addition, the polypeptides of the present invention can be fused to a marker sequence (eg, a peptide that facilitates purification of the fused polypeptide). In a preferred embodiment, the marker amino acid sequence is inter alia a hexa-histidine peptide (eg p
QE vector (QIAGEN, Inc., 9259 Eton Avenue,
Chatsworth, CA, 91311)),
Many of these marker amino acid sequences are commercially available. For example, Gentz et al., Proc. Natl. Acad. Sci. USA 86: 821-824 (1
989), hexa-histidine provides convenient purification of the fusion protein. Another peptide tag useful for purification, the "HA" tag, corresponds to an epitope derived from the influenza hemagglutinin protein (Wi.
Lson et al., Cell 37: 767 (1984)).

Thus, any of these above fusions can be engineered using the polynucleotides or polypeptides of the invention.

Vectors, Host Cells, and Protein Production The present invention also relates to vectors containing the polynucleotides of the present invention, host cells, and the production of polypeptides by recombinant techniques. For example, the vector can be a phage vector, a plasmid vector, a viral vector, or a retroviral vector. Retroviral vectors can be replication competent or replication defective. In the latter case, viral propagation generally will be complete (complementary).
only occurs in host cells.

The polynucleotide may be ligated to a vector containing a selectable marker for propagation in the host. Generally, the plasmid vector is introduced in a precipitate, such as a calcium phosphate precipitate, or in complex with a charged lipid. If the vector is a virus, it can be packaged in vitro using a suitable packaging cell line and then transduced into host cells.

The polynucleotide insert may be labeled with a suitable promoter (eg, the phage λPL promoter, the E. coli lac promoter, the trp promoter, the phoA promoter and the tac promoter, the SV40 early promoter and the SV40 late promoter, to name a few). Should be operably linked to the LTR promoter). Other suitable promoters are known to those of skill in the art. The expression construct further comprises sites for transcription initiation, transcription termination,
And in the transcribed region, it contains a ribosome binding site for translation. The coding portion of the transcript expressed by this construct is preferably a translation initiation codon initially, and a termination codon (U) appropriately located at the end of the polypeptide to be translated.

As indicated, the expression vector preferably contains at least one selectable marker. Such markers include dihydrofolate reductase, G418, or neomycin resistance genes for eukaryotic cell culture, as well as E. coli. It contains a tetracycline, kanamycin or ampicillin resistance gene for cultivation in E. coli and other bacteria. Representative examples of suitable hosts are bacterial cells (eg E. c.

Introduction of the construct into host cells is carried out by calcium phosphate transfection, DE
It can be provided by AE-dextran mediated transfection, cationic lipid mediated transfection, electroporation, transduction, infection, or other methods. Such methods are described by Davis et al., Basic Metho.
It is described in many standard laboratory manuals such as ds In Molecular Biology (1986). It is specifically contemplated that the polypeptides of the present invention may in fact be expressed by host cells lacking the recombinant vector.

The polypeptides of the present invention may be ammonium sulfate precipitated or ethanol precipitated, acid extracted, anion or cation exchange chromatography, phosphocellulose chromatography, hydrophobic interaction chromatography, affinity chromatography, hydroxylapatite chromatography and lectins. It can be recovered from recombinant cell culture and purified by well-known methods, including chromatography. Most preferably high performance liquid chromatography (“HPLC”)
Is used for purification.

The polypeptides of the invention, and preferably the secreted forms, may also be recovered from: purified from natural sources, including body fluids, tissues and cells, whether directly isolated or cultured. The product of a chemical synthesis procedure; and
Products recombinantly produced from prokaryotic or eukaryotic hosts, including, for example, bacterial cells, yeast cells, higher plant cells, insect cells, and mammalian cells. Depending on the host used in a recombinant production procedure, the polypeptides of the present invention may be glycosylated or non-glycosylated. In addition, the polypeptides of the present invention may also, in some cases, include an initial modified methionine residue as a result of host-mediated processes. Therefore, it is well known in the art that, in general, the N-terminal methionine encoded by the translation initiation codon is highly efficiently removed from any post-translational protein in all eukaryotic cells. N-terminal methionine is also effectively removed in most prokaryotes in most proteins, but for some proteins this prokaryotic removal process depends on the nature of the amino acids to which the N-terminal methionine is covalently attached. And is inefficient.

In one embodiment, the yeast Pichia pastoris is used to express a polypeptide of the invention in a eukaryotic cell line. Pichi
a pastoris is a methyltrophic yeast that can metabolize with methanol as its sole carbon source. The major step in the methanol metabolism pathway is the oxidation of methanol to formaldehyde using O ₂ . This reaction is catalyzed by the enzyme alcohol oxidase. In order to metabolize methanol as its sole carbon source, Pichia pas
toris produces high levels of alcohol oxidase, due in part to the relatively low affinity of alcohol oxidase for O ₂ . Consequently, the promoter region of one of the two alcohol oxidase genes (AOX1) is highly active in growth media that relies on methanol as the major carbon source. In the presence of methanol, the alcohol oxidase produced from the AOX1 gene comprises up to approximately 30% of total soluble protein in Pichia pastoris. Ellis, S .; B. Et al., Mol. Cell.

The strong AOX1 promoter linked to the alkaline phosphatase (PHO) secretion signal peptide (ie leader) allows expression and secretion of the proteins of the invention.

Many other yeast vectors (eg pYES2, pYD1, pTEF1 / Ze

Can be used in place of pPIC9K as long as it provides a good signal.

In another embodiment, high levels of expression of a heterologous coding sequence (eg, a polynucleotide of the invention, etc.) is obtained by cloning a heterologous polynucleotide of the invention into an expression vector (eg, pGAPZ or pGAPZalpha). , And can be achieved by growing the yeast culture in the absence of methanol.

The polypeptide may be modified at random positions within the molecule or at predetermined positions within the molecule and may contain one, two, three or more attached chemical moieties.

The polymer can be of any molecular weight and can be branched or unbranched.

Using polyethylene glycol as an illustration of the composition of the invention, from various polyethylene glycol molecules (by molecular weight, branching, etc.), the ratio of polyethylene glycol molecules to protein (polypeptide) molecules in the reaction mixture, the pegs to be performed. The type of oxidization reaction and the method of obtaining the selected N-terminal pegylated protein can be selected.

The selective protein chemically modified by N-terminal modification is
It can be achieved by reductive alkylation, which takes advantage of the differential reactivity of different types of primary amino groups (lysine vs. N-terminus) available for derivatization in a particular protein. Under appropriate reaction conditions, substantially selective derivatization of proteins at the N-terminus with a carbonyl group-containing polymer is achieved.

The homomers of the present invention are multimers that include polypeptides having different amino acid sequences. In certain embodiments, the multimers of the invention are homodimers (eg, including polypeptides having the same or different amino acid sequences) or homotrimers (eg, polypeptides having the same and / or different amino acid sequences).

In certain embodiments, the multimers of the invention are heterodimers, heterotrimers or heterotetramers. In a further embodiment, the heteromeric multimer of the invention is at least a heterodimer, at least a heterotrimer or at least a heterotetramer.

Thus, in one embodiment, multimers of the invention (eg, homodimers or homotrimers) are formed when the polypeptides of the invention contact each other in solution. In another embodiment, a heteromultimer of the invention (eg, a heterotrimer or heterotetramer, etc.) is a polypeptide of the invention in solution in which the antibody to the polypeptide of the invention (of the invention (Including antibodies to the heterologous polypeptide sequence in the fusion protein).

May be included. In one example, the covalent bond is a bridge between cysteine residues that are present within the polypeptide sequence that interact in the native (ie, naturally occurring) polypeptide. In another example, this covalent bond is the result of chemical or recombinant manipulation. Alternatively, such a covalent bond may comprise one or more amino acid residues contained in the heterologous polypeptide sequence in the fusion protein of the invention.

Another method for preparing the multimeric polypeptides of the invention involves the use of the polypeptides of the invention fused to a leucine zipper polypeptide sequence or an isoleucine zipper polypeptide sequence. Leucine zipper domains and isoleucine zipper domains are polypeptides that promote multimerization of the proteins in which they are found. The leucine zipper was originally identified in several DNA binding proteins (Landschulz et al., Science 240
: 1759, (1988)), and since then in a variety of different proteins. Particularly known leucine zippers are naturally occurring peptides and their derivatives that undergo dimerization or trimerization.

No. 5,478,925, which is incorporated herein by reference in its entirety).

Uses of Polynucleotides Each of the polynucleotides identified herein can be used as reagents in a number of ways. The following description should be considered exemplary and utilizes known techniques.

The polynucleotides of the present invention are useful for chromosome identification. Chromosome marking reagents based on actual sequence data (repeated polymorphisms) are currently scarcely available, so there remains a need to identify new chromosomal markers. Each polynucleotide of the present invention can be used as a chromosomal marker.

Briefly, the sequence can be mapped to the chromosome by preparing PCR primers (preferably 15-25 bp) from the sequence shown in SEQ ID NO: X. Primers can be selected using computer analysis so that they do not span more than one predicted exon in genomic DNA. These primers are then used to bind P of somatic cell hybrids containing individual human chromosomes.
Used for CR screening. Only the hybrid containing the human gene corresponding to SEQ ID NO: X produces an amplified fragment.

[0375] Similarly, somatic cell hybrids carry the polynucleotide P to a particular chromosome.
It provides a rapid method for CR mapping. Three or more clones can be assigned per day using a single thermal cycler. Moreover, sublocalization of the polynucleotide can be accomplished using a panel of specific chromosomal fragments. Other gene mapping strategies that may be used are in situ hybridization, labeled flow sorted.
flow sorted) pre-screening on the chromosome and pre-selection by hybridization to construct a chromosome-specific cDNA library.

The exact chromosomal location of the polynucleotide is also determined by the metaphase chromosomal spread (spr
ead) fluorescence in situ hybridization (FISH). This technique uses polynucleotides as short as 500 or 600 bases; however, 2,000-4,000 bp polynucleotides are preferred. For a review of this technology, see Verma et al., “Human Chromoso.
mes: a Manual of Basic Technologies ", Pe
See rgamon Press, New York (1988).

For chromosome mapping, polynucleotides may be used individually (to mark a single chromosome or a single site on that chromosome) or in panels (to mark multiple sites and / or multiple chromosomes). Can be done. Preferred polynucleotides correspond to the non-coding regions of cDNA. Because coding sequences tend to be more conserved within gene families, which increases the chance of cross-hybridization during chromosome mapping.

Once the polynucleotide has been mapped to a precise chromosomal location, the physical location of the polynucleotide can be used in linkage analysis. Linkage analysis establishes coinheritance between the chromosomal location and the presentation of a particular disease. (Disease mapping data is described in, for example, V. McKusick, Mendel.
ian Inheritance in Man (Johns Hopkins
(Available online through the University Welch Medical Library)). Given 1 megabase mapping resolution and 1 gene per 20 kb, the cDNA precisely localized to the chromosomal region associated with disease could be one of 50-500 potential causative genes.

Thus, once co-inheritance is established, differences in polynucleotides and corresponding genes between affected and unaffected individuals can be tested. First, visible structural changes in the chromosome (eg, deletions or translocations) are examined in chromosome spreads or by PCR. In the absence of structural changes, the presence of point mutations is confirmed. Mutations observed in some or all affected individuals but not in normal individuals indicate that this mutation may cause the disease.
However, complete sequencing of polypeptides and the corresponding genes from some normal individuals is required to distinguish mutations from polymorphisms. If a new polymorphism is identified, this polymorphic polypeptide can be used for further linkage analysis.

In addition, increased or decreased expression of genes in affected individuals compared to unaffected individuals can be assessed using the polynucleotides of the invention. Any of these changes (
Altered expression, chromosomal rearrangements, or mutations) can be used as a diagnostic or prognostic marker.

Accordingly, the present invention also provides a diagnostic method useful during the diagnosis of disorders, which method comprises the step of measuring the expression level of a polynucleotide of the present invention in cells or body fluids from an individual, and Comprising a step of comparing the measured gene expression level to a standard level of polynucleotide expression level, whereby an increase or decrease in gene expression level relative to a standard is indicative of a disorder.

In yet another embodiment, the invention comprises a kit for analyzing a sample for the presence of proliferative and / or cancerous polynucleotides from a test subject. In a general embodiment, the kit comprises at least one polynucleotide probe containing a nucleotide sequence that specifically hybridizes to a polynucleotide of the invention, and a suitable container. In this particular embodiment, the kit comprises two polynucleotide probes defining an internal region of a polynucleotide of the invention, wherein each probe comprises a 31 'mer end internal to this region. Has one chain. In a further embodiment, this probe may be useful as a primer for polymerase chain reaction amplification.

If the diagnosis of the disorder has already been made by conventional methods, the present invention is useful as an indicator of prognosis, whereby patients exhibiting enhanced or suppressed polynucleotide expression of the present invention are: Experience poor clinical outcome compared to patients expressing this gene at levels closer to standard levels.

By “measuring the expression level of a polynucleotide of the invention”, the level of a polypeptide of the invention or of the mRNA encoding this polypeptide is directly measured in a first biological sample. (Eg, by determining or assessing absolute protein or mRNA levels) or relative (
For example, it is intended to be qualitatively or quantitatively measured or assessed (either by comparison with polypeptide levels or mRNA levels in a second biological sample). Preferably, the polypeptide level or mRNA level in the first biological sample is measured or evaluated and compared to a standard polypeptide level or mRNA level, the standard being from an unimpaired individual. Determined by averaging the levels obtained from the second biological sample obtained or from a population of unimpaired individuals. As will be appreciated in the art, once standard polypeptide or mRNA levels are known, this can be used repeatedly as a standard for comparison.

By “biological sample” is intended any biological sample obtained from an individual, body fluid, cell line, tissue culture or other source that contains a polypeptide or mRNA of the invention. As shown, the biological sample is capable of expressing a body fluid containing the polypeptide of the invention (eg, semen, lymph, serum, plasma, urine, synovial fluid and spinal fluid), and the polypeptide of the invention. Includes other tissue sources found. Methods for obtaining tissue biopsies and body fluids from mammals are well known in the art. If the biological sample contains mRNA, tissue biopsy is a preferred source.

The methods provided above can preferably be applied to diagnostic methods and / or kits in which the polynucleotides and / or polypeptides are bound to a solid support. In one exemplary method, the support is described in US Pat. Nos. 5,837,832, 5,874,219 and 5,856,174, "
It can be a "gene chip" or a "biological chip". Further, such gene chips to which the polynucleotides of the invention are attached can be used to identify polymorphisms between this polynucleotide sequence and polynucleotides isolated from the test subject. Knowledge of such polymorphisms (ie their location as well as their presence) is valuable in identifying disease loci for many disorders, including cancerous diseases and conditions. Such methods are described in US Pat. Nos. 5,858,659 and 5,856,104. The United States patents referenced above are incorporated herein by reference in their entireties.

The present invention includes polynucleotides of the present invention that are chemically synthesized (ie, reproduced as peptide nucleic acid (PNA)) or synthesized according to other methods known in the art. The use of PNA serves as the preferred form when the polynucleotide is incorporated into a solid support, ie a gene chip. For the purposes of the present invention, peptide nucleic acid (PNA) is a DNA analog of the polyamide type, and monomer units for adenine, guanine, thymine and cytosine are commercially available (Perceptice Biosystems). Certain components of DNA (eg, phosphorus, phosphorus oxide or deoxyribose derivatives) are PN

As disclosed by Lsen, Nature 365, 666 (1993), PNAs bind specifically and tightly to complementary DNA strands and are not degraded by nucleases. In fact, PNA binds more strongly to DNA than does DNA itself. This is probably due to the absence of electrostatic repulsion between the two chains and also the more flexible polyamide backbone. By this, P
NA / DNA duplexes bind under a wider range of stringency conditions than DNA / DNA duplexes, making it easier to perform multiplex hybridization.
Due to the strong binding, smaller probes can be used than with DNA.
Furthermore, perhaps single base mismatches can be determined using PNA / DNA hybridizations. Because the single mismatch in the 15-mer PNA / DNA is 4 ° C to 16 ° C for the 15-mer duplex of DNA / DNA, whereas the melting point (T.sub.m) is 8-20. This is because the temperature is lowered by ° C.
Also, the absence of charged groups in the PNA means that hybridization can be done at low ionic strength and reduce possible interference by salts during the analysis.

The present invention is useful for the detection of cancer in mammals. In particular, the invention is
Useful during diagnosis of pathological cell proliferative neoplasia, including but not limited to: acute myeloid leukemia (acute monocytic leukemia, acute myeloblastic leukemia, acute promyelocytic leukemia, Acute myelomonocytic leukemia, acute erythroleukemia, acute megakaryocytic leukemia,
And acute undifferentiated leukemia); and chronic myelogenous leukemia (including chronic myelomonocytic leukemia, chronic granulocytic leukemia, etc.). Preferred mammals include monkeys, apes, cats, dogs, cows, pigs, horses, rabbits and humans. Especially preferred is human.

Neoplasia is now from qualitative alterations of the normal cellular gene product, by the insertion of viral sequences into the chromosome, chromosomal translocations of genes into more actively transcribed regions, or by some other mechanism, or of gene expression. It is believed to result from quantitative modification (Gelmann et al., Supra). Mutated or altered expression of certain genes appears to be involved in the pathogenesis of some leukemias, among other tissues and other cell types (Gelmann et al., Supra).
In fact, human counterparts of some animal neoplastic oncogenes have been amplified or translocated in some cases of human leukemia and cancer (Gelmann).

However, one of ordinary skill in the art will find the utility of the present invention in view of the large number of cells and cell types of various origins known to exhibit a proliferative phenotype, proliferative diseases, disorders of hematopoietic cells and tissues. And / or recognize that treatment of the condition is not limited.

In addition to the above, the polynucleotide may be triple helix formed or antisense DN.
It can be used to control gene expression through A or RNA. Antisense technology is described in, for example, Okano, J. et al. Neurochem. 56: 560 (1

Triple helix formation optimally results in the blockage of RNA transcription from DNA, whereas antisense RNA hybridization blocks translation of mRNA molecules into polypeptides. Both techniques are effective in model systems, and the information disclosed herein can be used to design antisense or triple helix polynucleotides in an attempt to treat disease.

The polynucleotides of the present invention are also useful in gene therapy. One goal of gene therapy is to insert a normal gene into an organism that has a defective gene in an attempt to correct the genetic defect. The polynucleotide disclosed in the present invention is
It provides a means to target such genetic defects in a highly accurate manner. Another goal is to insert new genes that were not present in the host genome, thereby creating new traits in the host cell.

Polynucleotides are also useful for identifying an individual from a small biological sample. For example, the United States military is considering the use of restriction fragment length polymorphisms (RFLPs) to identify its personnel. In this technique, an individual's genomic DNA is digested with one or more restriction enzymes and probed for Southern blots to generate unique bands to identify staff. This method does not suffer from the current limitations of the "Dog tag," which can be difficult to positively identify by being lost, exchanged, or stolen. The polynucleotide of the present invention can be used as an additional DNA marker for RFLP.

The polynucleotides of the present invention can also be used as an alternative to RFLP by determining the actual base-by-base DNA sequence of selected portions of the genome of an individual. These sequences can be used to prepare PCR primers to amplify and isolate such selected DNA, which can then be sequenced. Individuals can be identified using this technique because each individual has a unique set of DNA sequences. Once a unique ID database is established for an individual, whether that individual is alive or dead, positive identification of that individual can be made from a very small tissue sample.

Forensic biology will also benefit using DNA-based identification techniques as disclosed herein. Tissue (eg hair or skin) or body fluid (eg blood, saliva, semen, synovial fluid, amniotic fluid, milk, lymph, lung sp (pulmonary sp)
DNA) obtained from a very small biological sample, such as urium) or surfactant, urine, fecal material, etc.) can be amplified using PCR.
In one prior art, gene sequences amplified from polymorphic loci such as the DQa class II HLA gene are used in forensic biology to identify individuals. (Errich, H., PCR Technology, Freem.
an and Co. (1992)). Once these specific polymorphic loci are amplified, they are digested with one or more restriction enzymes. This results in an identified set of bands for Southern blots probed with DNA corresponding to the DQa class II HLA gene. Similarly, the polynucleotides of the present invention can be used as polymorphic markers for forensic purposes.

There is also a need for reagents that can identify the source of a particular tissue. Such a need arises in forensic medicine, for example, if tissue of unknown origin is provided. Suitable reagents may include, for example, DNA probes or primers specific to a particular tissue prepared from the sequences of the invention. Such a panel of reagents may identify tissues by species and / or organ type. In a similar fashion, these reagents can be used to screen tissue cultures for contaminants.

At a minimum, the polynucleotides of the present invention “subtract from known sequences in the process of discovering novel polynucleotides as molecular weight markers in Southern gels, as diagnostic probes for the presence of specific mRNAs in specific cell types. As a probe for "selecting and making oligomers for attachment to a" gene chip "or other support, for raising anti-DNA antibodies using DNA immunization techniques, and for eliciting an immune response. Can be used as

Uses of Polypeptides Each of the polypeptides identified herein can be used in a number of ways. The following description should be considered exemplary and utilizes known techniques.

The polypeptides of the present invention can be used to assay protein levels in biological samples using antibody-based techniques. For example, protein expression in tissues can be studied using classical immunohistochemistry (Jalka).
nen, M .; Et al., J. Cell. Biol. 101: 976-985 (1985)
); Jalkanen, M .; Et al., J. Cell. Biol. 105: 3087-
3096 (1987)). Other antibody-based methods useful for detecting protein gene expression include immunoassays such as enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA). Suitable antibody assay labels are known in the art and include, for example, enzyme labels such as glucose oxidase, as well as iodine (125I, 121I), carbon (14I).
C), sulfur (35S), tritium (3H), indium (112In), and radioisotopes such as technetium (99mTc), and fluorescent labels such as fluorescein and rhodamine, and biotin.

In addition to assaying secreted protein levels in biological samples, proteins can also be detected in vivo by imaging. Antibody labels or markers for in vivo imaging of proteins include those detectable by X-ray radiography, NMR or ESR. For x-ray radiography, suitable labels include radioisotopes such as barium or cesium that emit detectable radiation but are not overtly harmful to the subject. NM
Suitable markers for R and ESR include those with a detectable characteristic spin, such as deuterium, which can be incorporated into antibodies by labeling the nutrients for the relevant hybridoma. .

Protein-specific, labeled with a suitable detectable imaging moiety, such as a radioisotope (eg, 131I, 112In, 99mTc), radiopaque material, or material detectable by nuclear magnetic resonance. The antibody or antibody fragment is introduced into a mammal (eg, parenterally, subcutaneously, or intraperitoneally). It is understood in the art that the size of the subject and the imaging system used will determine the amount of imaging moiety needed to produce a diagnostic image. In the case of a radioisotope moiety,
For human subjects, the amount of radioactivity injected is usually about 5-20 mTc.
It is in the millimeter range. The labeled antibody or antibody fragment will then preferentially accumulate at the location of cells which contain the particular protein. In vivo tumor imaging is described by S. W. Burchiel et al., “Immunopharmacokine
tics of Radiolabeled Antibodies and
Their Fragments. "(Tumor Imaging: The

Publishing Inc. (1982)).

Accordingly, the invention provides a method of diagnosing a disorder, which method comprises (a) assaying the expression of a polypeptide of the invention in cells or body fluids of an individual; (b) the level of expression of this gene. Is compared to a standard gene expression level, whereby an increase or decrease in the gene expression level of the assayed polypeptide relative to the standard expression level is indicative of a disorder. For cancer, may the presence of relatively high abundance of transcripts in biopsied tissue from an individual predispose to the development of this disease?
Alternatively, it may provide a means to detect this disease prior to the onset of actual clinical symptoms.
A more definitive diagnosis of this type may allow health professionals to use earlier preventative measures or aggressive treatments, thereby preventing the onset or further progression of cancer.

In addition, the polypeptides of the present invention may be used to treat, prevent and / or diagnose disease. For example, in a patient, replacing the absence or reduced level of a polypeptide (eg, insulin) with a different polypeptide (eg, hemoglobin B).
Absent or reduced levels of hemoglobin S, SOD, catalase, DNA repair proteins) against, inhibiting the activity of the polypeptide (eg, oncogene or tumor suppressor), the activity of the polypeptide (eg, Activating (by binding to a receptor), decreasing the activity of a membrane bound receptor by competing with the membrane bound receptor for free ligands (eg soluble TNF receptors used in reducing inflammation), or Polypeptides of the invention can be administered in addressing to produce a desired response (eg, inhibition of blood vessel growth, enhancement of immune response to proliferating cells or tissues).

Similarly, antibodies to the polypeptides of the present invention may also be used to treat, prevent and / or diagnose disease. For example, administration of an antibody to a polypeptide of the invention may bind to the polypeptide and reduce overproduction of the polypeptide. Similarly, administration of an antibody may activate that polypeptide, for example, by binding to a membrane-bound polypeptide (receptor).

At least the polypeptides of the invention are SDS-P using methods well known to those of skill in the art.
It can be used as a molecular weight marker in AGE gel or molecular sieve gel filtration columns. Polypeptides can also be used to raise antibodies, which are then used to measure protein expression from recombinant cells as a method of assessing transformation of host cells. In addition, the polypeptides of the invention can be used to test the following biological activities.

This gene therapy method uses nucleic acid (DNA, RNA, and antisense DNA or RNA to achieve expression of the polypeptide of the present invention.

In one embodiment, the engineered cells are arterial cells. The arterial cells can be reintroduced into the patient by direct injection into the arteries, tissues surrounding the arteries, or by catheter injection.

[0407] As discussed in more detail below, the polynucleotide constructs may be administered by any method that delivers an injectable substance to cells of an animal, such as tissue (heart, muscle, skin,
Injection into the interstitial space of the lungs, liver, etc.). The polynucleotide construct can be delivered in a pharmaceutically acceptable liquid or aqueous carrier.

In one embodiment, the polynucleotides of the present invention are delivered as naked polynucleotides. The term "naked" polynucleotide, DNA or RNA refers to any delivery vehicle (that acts to assist, facilitate or facilitate entry into cells.
(Including viral sequences, viral particles, liposomal formulations, lipofectin, precipitants, etc.). However, the polynucleotides of the invention can also be delivered in liposomal formulations, and lipofectin formulations and the like can be prepared by methods well known to those of skill in the art. Such methods are described, for example, in US Pat. Nos. 5,593,972 and 5,589, incorporated herein by reference.

Any strong promoter known to those of skill in the art can be used to drive the expression of the polynucleotide sequences of the present invention. Suitable promoters include adenovirus promoters (eg, adenovirus major late promoter); or heterologous promoters (eg, cytomegalovirus (CMV) promoter);
RS virus (RSV) promoter; inducible promoter (eg MMT promoter, metallothionein promoter); heat shock promoter; albumin promoter; ApoAI promoter; human globin promoter; viral thymidine kinase promoter (eg herpes simplex thymidine kinase promoter); retrovirus LTR; b-actin promoter; and human growth hormone promoter. The promoter can also be the native promoter for the polynucleotides of the invention.

Unlike other gene therapy techniques, one major advantage of introducing a naked nucleic acid sequence into a target cell is the transient nature of polynucleotide synthesis in that cell. Studies have shown that non-replicating DNA sequences can be introduced into cells to provide for production of the desired polypeptide for a period of up to 6 months.

The polynucleotide construct of the present invention can be used for tissue (animal, skin, brain, lung, liver, spleen, bone marrow, thymus, heart, lymph, blood, bone, cartilage, pancreas, kidney, gallbladder, stomach, in animal, Includes intestines, testes, ovaries, uterus, rectum, nervous system, eyes, glands, and connective tissue)

For naked nucleic acid sequence injection, the effective dosage of DNA or RNA is about 0.05.
It ranges from mg / kg body weight to about 50 mg / kg body weight. Preferably, this dosage is about 0.005 mg / kg to about 20 mg / kg, and more preferably about 0.05 mg / kg to about 5 mg / kg. Of course, as the skilled artisan will appreciate, this dosage will vary depending on the tissue site of injection. Suitable and effective dosages of nucleic acid sequences can be readily determined by those of ordinary skill in the art and may depend on the condition being treated and the route of administration.

The preferred route of administration is by the parenteral route of injection into the interstitial space of tissues. However, other parenteral routes may also be used, including, for example, inhalation of aerosol formulations, especially for delivery to lung or bronchial tissues, throat or mucous membranes of the nose, among others. In addition, naked DNA constructs can be delivered to arteries during angioplasty by the catheter used in this procedure.

Naked polynucleotides can be any method known in the art including, but not limited to, direct needle injection at the site of delivery, intravenous injection, topical administration, catheter infusion, and so-called “gene gun”. Delivered by. These methods of delivery are known in the art.

The constructs can also be delivered using delivery vehicles such as viral sequences, viral particles, liposomal formulations, lipofectins, precipitants and the like. Such delivery methods are known in the art.

In certain embodiments, the polynucleotide constructs of the present invention are complexed in liposome preparations. Liposomal preparations for use in the present invention include cationic (positively charged), anionic (negatively charged) and neutral preparations. However, cationic liposomes are particularly preferred because they can form a robust charge complex between the cationic liposomes and the polyanionic nucleic acid. Cationic liposomes, in functional form, are plasmid DNA (Felgner et al., Proc. Natl. Acad. S, incorporated herein by reference).
ci. USA, 84: 7413-7416 (1987)); mRNA (Malone et al., Proc. Natl. Acad., Incorporated herein by reference).

hem. , 265: 10189-10192 (1990)) has been shown to mediate intracellular delivery.

Cationic liposomes are readily available. For example, N [1-2,3-dioleyloxy) propyl] -N, N, N-triethylammonium (DOTM
A) Liposomes are particularly useful, and are available under the trademark Lipofectin® from GIBCO BRL, Grand Island, N.F. Y. (Felgner et al., Proc. Natl. Acad. Sc, incorporated herein by reference.
i. USA, 84: 7413-7416 (1987)). Other commercially available liposomes include transfectase (t

(Boehringer).

Other cationic liposomes can be prepared from readily available materials using techniques well known in the art. DOTAP (1,2-bis (oleoyloxy)-
For a description of the synthesis of 3- (trimethylammonio) propane) liposomes, see, eg, PCT Publication No. WO 90/11092, which is incorporated herein by reference. The preparation of DOTMA liposomes has been described in the literature and is described, for example, in Felgner et al., Proc. Na
tl. Acad. Sci. USA, 84: 7413-7417. Similar methods can be used to prepare liposomes from other cationic lipid substances.

Similarly, anionic and neutral liposomes can be prepared, for example, by Avant.
It is readily available from i Polar Lipids (Birmingham, Ala.) or can be easily prepared using readily available materials.
Such substances include, among others, phosphatidylcholine, cholesterol, phosphatidylethanolamine, dioleoylphosphatidylcholine (DOPC).

It can be mixed with DOTMA starting material and DOTAP starting material in suitable proportions. Methods of using these materials to form liposomes are well known in the art.

For example, commercially, dioleoylphosphatidylcholine (DOPC), dioleoylphosphatidylglycerol (DOPG), and dioleoylphosphatidylethanolamine (DOPE) were used in various combinations, with the addition of cholesterol. Even without, conventional liposomes can be produced. Therefore,
For example, DOPG / DOPC vesicles can be prepared by drying 50 mg each of DOPG and DOPC under a stream of nitrogen gas into a sonicated vial. The sample is placed under vacuum pump overnight and hydrated the next day with deionized water. This sample was then placed in a capped vial using a Heat Systems Model 350 sonicator equipped with an inverted cup (bath type) probe at maximum setting while the bath was circulating at 15 EC. Sonicate for 2 hours. Alternatively, negatively charged vesicles can be prepared without sonication to generate multilamellar vesicles or extruded through nucleopore membranes to separate unilamellar vesicles of different sizes. Can be generated. Other methods are known and available to those of skill in the art.

The liposomes can include multilamellar vesicles (MLVs), small unilamellar vesicles (SUVs) or large unilamellar vesicles (LUVs), with SUVs being preferred. Various liposome-nucleic acid complexes are prepared using methods well known in the art. For example, Straubinge, which is incorporated herein by reference.
r et al., Methods of Immunology, 101: 512-527.
(1983). For example, MLVs containing nucleic acids can be prepared by depositing a thin film of phospholipids on the walls of glass tubes and then hydrating with a solution of the substance to be encapsulated. SUVs are prepared by long-term sonication of MLVs, producing a homogeneous population of unilamellar vesicles. The substance to be encapsulated is added to a suspension of preformed MLVs and then sonicated. When using liposomes containing cationic lipids, dry lipid membranes should be treated with sterile water or 10
Resuspend in a suitable solution, such as an isotonic buffer solution such as mM Tris / NaCl, sonicate, then mix the preformed liposomes directly with the DNA. Due to the binding of the positively charged liposomes to the cationic DNA, the liposomes and DNA form a very stable complex. SUVs find use with small nucleic acid fragments. LUVs are prepared by many methods well known in the art. A commonly used method is Ca ²⁺ -EDTA chelation (Pap

Such means, electroporation, the use of liposomes, and CaPO ₄ precipitation include, but are not limited to. In one alternative, the retroviral plasmid vector can be encapsulated in liposomes or attached to lipids and then administered to a host.

This producer cell line produces infectious retroviral vector particles which contain a polynucleotide encoding a polypeptide of the invention. Such retroviral vector particles can then be used to transduce eukaryotic cells either in vitro or in vivo. The transduced eukaryotic cell expresses a polypeptide of the invention.

In certain other embodiments, the polynucleotides of the invention contained in adenovirus vectors are used to engineer cells ex vivo or in vivo. Adenovirus can be engineered so that it encodes and expresses the polypeptide of the invention, while at the same time being inactivated with respect to its ability to replicate in the normal lytic viral life cycle. Adenovirus expression is achieved without integration of the viral DNA into the host cell chromosome, resulting in less worry about insertional mutagenesis. Furthermore, adenovirus has been used for many years as a live vaccine for the intestine with excellent safety aspects (Schwartzet et al., Am. Re.
v. Respir. Dis. , 109: 233-238 (1974)). Finally, adenovirus-mediated gene transfer has been demonstrated in many cases, including the transfer of α-1-antitrypsin and CFTR into the lungs of cotton rats (Ro.
senfeld et al., Science, 252: 431-434 (1991); R.

These cells contain the adenovirus E1 region and constitutively express Ela and Elb, which complement the defective adenovirus by providing the product of the gene deleted from this vector. . In addition to Ad2, a variety of other adenoviruses (eg, Ad3, Ad5, and Ad7) are also useful in the present invention.

[0430] Preferably, the adenovirus used in the present invention is replication defective. Replication-defective adenoviruses require the help of helper viruses and / or packaging cell lines to form infectious particles. The resulting virus is capable of infecting cells and can express the polynucleotide of interest operably linked to a promoter, but is unable to replicate in most cells. A replication-defective adenovirus can be deleted at one or more of the following genes: E1a, E1b, E3, E4, E2a or all or part of L1 to L5.

In certain other embodiments, adeno-associated virus (AAV) is used to engineer the cells ex vivo or in vivo. AAV is a naturally occurring defective virus that requires a helper virus to produce infectious particles (

A polynucleotide construct containing a polynucleotide of the invention is inserted into this AAV vector using standard cloning methods, such as the method found in 89). The recombinant AAV vector is then transfected into packaging cells infected with helper virus using any standard technique, including lipofection, electroporation, calcium phosphate precipitation and the like. Suitable helper viruses include adenovirus, cytomegalovirus, vaccinia virus, or herpes virus. Once the packaging cells are transfected and infected, they produce infectious AAV viral particles that include the polynucleotide constructs of the invention. These viral particles are then used to transduce eukaryotic cells, either ex vivo or in vivo. The transduced cell contains the polynucleotide construct integrated into its genome and expresses the desired gene product.

Another method of gene therapy is homologous recombination (see, eg, US Pat. No. 5,641,67).

342: 435-438 (1989)). Including. The method involves activation of a gene that is present in the target cell but is normally not expressed in that cell or is expressed at a lower level than desired.

Polynucleotide constructs are made using standard techniques known in the art. This construct contains a promoter with targeting sequences flanking the promoter. Suitable promoters are described herein. The targeting sequence is sufficiently complementary to the endogenous sequence to allow homologous recombination between the promoter-targeting sequence and the endogenous sequence. The targeting sequence is located sufficiently close to the 5'end of the desired endogenous polynucleotide sequence so that upon homologous recombination the promoter is operably linked to the endogenous sequence.

The promoter and targeting sequence can be amplified using PCR. Preferably, the amplified promoter contains additional restriction enzyme sites at the 5'and 3'ends. Preferably, the 3'end of the first targeting sequence contains the same restriction enzyme sites as the 5'end of the amplified promoter, and the 5'end of the second targeting sequence contains the 3'end of the amplified promoter. Includes the same restriction sites as the termini. The amplified promoter and targeting sequences are digested and ligated together.

Liposomes, viral sequences, viral particles, whole viruses, lipofections, either as naked polynucleotides or as described in more detail above.
The promoter-targeting sequence construct is delivered to cells, either with a transfection facilitating agent such as a precipitating agent. Direct needle injection, intravenous injection,
The P promoter-targeting sequence may be delivered by any method, including local administration, catheter infusion, particle accelerators and the like. This method is described in more detail below.

The promoter-targeting sequence construct is taken up by cells. Homologous recombination occurs between this construct and the endogenous sequence, so that the endogenous sequence is placed under the control of this promoter. This promoter then drives the expression of the endogenous sequence.

Polynucleotides encoding the polypeptides of the present invention may be administered with other polynucleotides encoding other angiogenic proteins. Angiogenic proteins include acidic and basic fibroblast growth factor, VEGF-1, VEG
F-2 (VEGF-C), VEGF-3 (VEGF-B), epidermal growth factor α and β, platelet-derived endothelial cell growth factor, platelet-derived growth factor, tumor necrosis factor α,
Hepatocyte growth factor, insulin-like growth factor, colony stimulating factor, macrophage colony stimulating factor, granulocyte / macrophage colony stimulating factor, and nitric oxide synthase, but are not limited thereto.

[0439] Preferably, the polynucleotide encoding the polypeptide of the present invention comprises a secretory signal sequence that promotes secretion of the protein. Typically, the signal sequence is located in the coding region of the polynucleotide, expressed towards or at the 5'end of the coding region of the polynucleotide. The signal sequence may be homologous or heterologous to the polynucleotide of interest and homologous or heterologous to the transfected cells. In addition, the signal sequence can be chemically synthesized using methods known in the art.

Any dosage form of any of the above polynucleotide constructs may be used, so long as the dosage form expresses one or more molecules in an amount sufficient to provide a therapeutic effect. . This includes direct needle injections, systemic injections, catheter injections, biolistic injectors, particle accelerators (ie "gene guns"), gel foam sponge depots, and other commercial depots.
pot) substances, osmotic pumps (eg Alza minipumps), solid (tablets or pills) pharmaceutical formulations for oral or suppository, and intra-operative decanting or topical application. For example, direct injection of calcium phosphate-precipitated naked plasmid into rat liver and rat spleen or direct injection of protein-coated plasmid into the portal vein resulted in gene expression of foreign genes in rat liver (Ka
neda et al., Science, 243: 375 (1989)).

The preferred method of local administration is by direct injection. Preferably, the recombinant molecule of the present invention complexed with the delivery vehicle is administered by direct injection within the arterial region or locally within the arterial region. Topical administration of the composition within the arterial region refers to injection of the composition into the artery several centimeters, preferably several millimeters.

Another method of topical administration is to contact the polynucleotide constructs of the invention within or around a surgical wound. For example, a patient can undergo surgery and the polynucleotide construct can be coated on the tissue surface inside the wound or the construct can be injected into the tissue area inside the wound.

Therapeutic compositions useful for systemic administration include a recombinant molecule of the present invention complexed with a targeted delivery vehicle of the present invention. Suitable delivery vehicles for use in systemic administration include liposomes containing ligands that target the vehicle to a particular site.

Preferred methods of systemic administration include intravenous injection, aerosol, oral and transdermal (topical) delivery. Intravenous injections may be performed using methods standard in the art. Aerosol delivery may also be performed using methods standard in the art (eg, Stribling, incorporated herein by reference).

Mention may be made of plastic capsules or tablets, such as those known in the art. Topical delivery may be accomplished by mixing a lipophilic reagent (eg DMSO) that is capable of passing into the skin with a polynucleotide construct of the present invention.

Determining the effective amount of a substance to be delivered can be determined, for example, by the chemical structure and biological activity of the substance, the age and weight of the animal, the exact condition requiring treatment and its severity, and administration. It may depend on a number of factors, including the pathway. The frequency of treatment is

If these polynucleotides and polypeptides show activity in a particular assay, it is likely that these molecules may be involved in diseases associated with their biological activity. Accordingly, the polynucleotides or polypeptides, or agonists or antagonists, can be used to treat associated diseases.

Immune cells develop through a process called hematopoiesis, producing myeloid cells (platelets, erythrocytes, neutrophils and macrophages) and lymphoid cells (B and T lymphocytes) from pluripotent stem cells. The etiology of these immune diseases, disorders and / or conditions may be genetic, somatic (eg cancer or some autoimmune diseases, disorders,
And / or conditions), acquired (eg, due to chemotherapy or toxins) or infectious. Furthermore, the polynucleotide or polypeptide of the present invention,
Or agonists or antagonists can be used as markers or detectors of particular immune system diseases or disorders.

The polynucleotides or polypeptides, or agonists or antagonists of the invention, may be useful in treating, preventing, and / or diagnosing hematopoietic cell diseases, disorders and / or conditions. The polynucleotides or polypeptides, or agonists or antagonists of the invention, are pluripotent in an attempt to treat or prevent diseases, disorders, and / or conditions associated with the reduction of certain (or many) types of hematopoietic cells. It can be used to increase the differentiation and proliferation of hematopoietic cells, including stem cells. Examples of immunodeficiency syndromes are blood protein diseases, disorders, and / or conditions (eg, agammaglobulinemia, hypogammaglobulinemia), ataxia-telangiectasia, unclassified immunodeficiency, di George syndrome, HIV infection, HTLV-BLV infection, leukocyte adhesion deficiency syndrome, lymphopenia, phagocytic bactericidal dysfunction, severe combined immunodeficiency (SCID), Viscott-Aldrich disorder, anemia, thrombocytopenia, or hemoglobin Examples include, but are not limited to, uremia.

In addition, the polynucleotides or polypeptides of the invention, or agonists or antagonists, may also be used to modulate hemostatic activity (stop bleeding) or thrombolytic activity (clot formation).

The polynucleotides or polypeptides of the invention, or agonists or antagonists, may also be useful in the treatment, prevention and / or diagnosis of autoimmune diseases, disorders and / or conditions. Many autoimmune diseases, disorders and / or conditions result from improper self-recognition as foreign substances by immune cells. This improper recognition triggers an immune response that results in the destruction of host tissue. Thus, administration of a polynucleotide or polypeptide of the invention, or an agonist or antagonist, that inhibits an immune response, particularly T cell proliferation, differentiation or chemotaxis, is useful in the prevention of autoimmune diseases, disorders and / or conditions. It can be an effective treatment.

Administration of a polynucleotide or polypeptide of the invention, or an agonist or antagonist that inhibits an immune response, particularly T cell proliferation, differentiation or chemotaxis, may be an effective treatment in preventing organ rejection or GVHD.

Similarly, the polynucleotides or polypeptides of the invention, or agonists or antagonists, may also be used to modulate inflammation. For example, the polypeptide or polynucleotide, or agonist or antagonist, may inhibit proliferation and differentiation of cells involved in the inflammatory response. Using these molecules, chronic prostatitis, granulomatous prostatitis and malacoplakia, infection-related inflammation (eg, septic shock, sepsis, or systemic inflammatory response syndrome (SI

Anti-Angiogenic Activity The naturally occurring equilibrium between endogenous stimulators and inhibitors of angiogenesis is the equilibrium in which the inhibitory effects predominate. Rastinejad et al., Cell 5
6: 345-355 (1989). In rare cases where neovascularization occurs under normal physiological conditions (eg, wound healing, organ regeneration, embryogenesis, and female reproductive processes), angiogenesis is tightly regulated and spatial and temporal. It is specified. Conditions for pathological angiogenesis (eg, characterizing solid tumor growth)
Below, there is no control over these adjustments. Unregulated angiogenesis becomes pathological and maintains the progression of many neoplastic and non-neoplastic diseases. Many serious diseases are dominated by abnormal neovascularization, including solid tumor growth and metastasis, arthritis, some types of ocular diseases, disorders and / or conditions, and psoriasis.

Examples of such molecules include antibodies, oligonucleotides, proteins (eg receptors), or small molecules.

Preferably, the molecule is closely related to the natural ligand (eg, fragment of the ligand) of the polypeptide or natural substrate, ligand, structural mimetic, or functional mimic (Coligan et al. , Current Prot
ocols in Immunology 1 (2): Chapter 5 (1991)). Similarly, the molecule may be intimately associated with the natural receptor to which the polypeptide binds, or at least a fragment of the receptor (eg, the active site) that may be bound by the polypeptide. In any case, the molecule can be rationally designed using known techniques.

Preferably, screening for these molecules involves producing appropriate cells that express the polypeptide, either as a secreted protein or on the cell membrane. Preferred cells include mammals, yeast, Drosoph
ila, or E.I. cells derived from E. coli. The cells expressing the polypeptide (or cell membranes containing the expressed polypeptide) are then preferably observed for binding, stimulating, or inhibiting activity of either the polypeptide or the molecule. Are contacted with a test compound potentially containing the molecule of

The assay may simply test the binding of a candidate compound to the polypeptide, where binding is detected by the label or in an assay for competition with a labeled competitor. In addition, the assay can test whether a candidate compound produces a signal generated by binding to this polypeptide.

Alternatively, the assay can be performed with cell-free preparations, polypeptides / molecules attached to a solid support, chemical libraries, or a mixture of natural products. The assay also simplifies the steps of mixing the candidate compound with a solution containing the polypeptide, measuring the activity or binding of the polypeptide / molecule, and comparing the activity or binding of the polypeptide / molecule to a standard. May be included.

Preferably, the ELISA assay may measure the level or activity of a polypeptide in a sample (eg, biological sample) using monoclonal or polyclonal antibodies. Antibodies may be bound to the polypeptide either directly or indirectly, or by competition with the polypeptide for a substrate,
The level or activity of the polypeptide can be measured.

Furthermore, the receptors to which the polypeptides of the invention bind may be obtained by a number of methods known to those skilled in the art, such as ligand panning and FACS sorting (Coliga).

Chapter 5 (1991)). For example, expression cloning is used when polyadenylated RNA is prepared from cells responsive to this polypeptide, eg, NIH3T3 cells, which are known to contain multiple receptors for FGF family proteins, And SC-3 cells, and a cDNA library made from this RNA are pooled and used to transfect COS cells or other cells that are not responsive to the polypeptide. Transfected cells growing on glass slides are exposed to the polypeptides of the invention after labeling them. The polypeptide may be labeled by various means, including iodination or encapsulation of recognition sites for site-specific protein kinases.

After immobilization and incubation, slides are subjected to autoradiographic analysis. Positive pools are identified and subpools are prepared and retransfected using an iterative subpooling and rescreening process to ultimately yield a single clone encoding the putative receptor.

As an alternative approach for receptor identification, labeled polypeptides may be photoaffinity-linked or extracted with a preparation expressing the receptor molecule, photoaffinity. The crosslinked material is separated by PAGE analysis and exposed to X-ray film. A labeled complex containing the receptor for the polypeptide can be excised,
It can be separated into peptide fragments and subjected to protein microsequencing. The amino acid sequence obtained from microsequencing is used to design a set of degenerate oligonucleotide probes to screen a cDNA library to identify the gene encoding the putative receptor.

Such methods include the steps of contacting the polypeptides of the invention with selected compounds suspected of having antagonistic or agonistic activity, and assaying the activity of these polypeptides following binding. To do.

The present invention is particularly useful for screening therapeutic compounds by using the polypeptides of the present invention, or binding fragments thereof, in any of a variety of drug screening techniques. The polypeptide or fragment used in such a test can be immobilized on a solid support, expressed on the cell surface, free in solution, or localized intracellularly.

For example, the use of the c-myc and c-myb antisense RNA constructs to inhibit the growth of the non-lymphocytic leukemia cell line HL-60 and other cell lines has been previously described (Wickstrom et al. 1988); Anfossi et al.

It is described in WO 91/15580. Briefly, a pair of oligonucleotides for a given antisense RNA is generated as follows: a sequence complementary to the first 15 bases of the open reading frame, an EcoRI site at the 5'end and a HindIII at the 3'end. Adjacent to the site. The oligonucleotide pairs are then heated at 90 ° C. for 1 minute and then 2 × ligation buffer (20 mM TRIS HC
pH 7.5, 10 mM MgCl ₂ , 10 mM dithiothreitol (DT

/ 15580).

For example, the 5'coding portion of the polynucleotide encoding the mature polypeptide of the invention can be used to design an antisense RNA oligonucleotide of about 10-40 base pairs in length. DNA oligonucleotides are designed to be complementary to regions of the gene involved in transcription, thereby inhibiting transcription and production of receptors. The antisense RNA oligonucleotide hybridizes to the mRNA in vivo and blocks translation of the mRNA molecule into a receptor polypeptide.

In one embodiment, the antisense nucleic acids of the invention are produced intracellularly by transcription from a foreign sequence. For example, the vector or a portion thereof is transcribed to produce the antisense nucleic acid (RNA) of the invention. Such a vector contains a sequence encoding the antisense nucleic acid of the present invention. Such a vector can be episomal or chromosomally integrated, as long as it can be transcribed to produce the desired antisense RNA. Such vectors can be constructed by recombinant DNA technology methods standard in the art. The vector can be a plasmid, virus, etc. known in the art used for replication and expression in vertebrate cells. Expression of sequences encoding the polypeptides of the present invention or fragments thereof may be obtained by any promoter known in the art to act in vertebrate, preferably human cells. Such promoters can be inducible or constitutive. Such promoters include the SV40 early promoter region (Bernist and Chambon, Nature, 29: 304-3.

The antisense nucleic acid of the present invention contains a sequence complementary to at least a part of RNA transcript of the gene of interest. However, perfect complementarity, although preferred, is not necessary. A sequence "complementary to at least a portion of RNA" as referred to herein means a sequence that has sufficient complementarity to hybridize with RNA and forms a stable duplex; Thus, in the case of the double-stranded antisense nucleic acids of the invention, single strands of double-stranded DNA can be tested or triplex formation can be assayed.
The ability to hybridize depends on both the degree of complementarity and the length of the antisense nucleic acid. In general, longer hybridizing nucleic acids may contain more base mismatches with the RNA sequences of the invention, which may include stable duplexes (or possibly triplexes), And yet it can be formed. One of skill in the art can ascertain the degree of mismatch tolerance by using standard procedures to determine the melting temperature of the hybridizing complex.

Oligonucleotides that are complementary to the 5'end of the message (eg, 5'untranslated sequences up to and including the AUG start codon) should work most efficiently in inhibiting translation. is there. However, sequences complementary to the 3'untranslated sequences of mRNAs have likewise been shown to be effective in inhibiting translation of mRNAs. Generally, Wagner, R .; , Nature 372: 333-335 (199).

On the other hand, a ribozyme that cleaves an mRNA at a site-specific recognition sequence can be used to destroy the mRNA corresponding to the polynucleotide of the present invention, but it is preferable to use a hammerhead ribozyme. Hammerhead ribozymes cleave mRNAs at positions determined by flanking regions that form complementary base pairs with the target mRNA. The only requirement is that the target mRNA has the following two base sequences: 5'-UG-3 '. Construction and production of hammerhead ribozymes is well known in the art, and Haseloff and Ge

Preferably, the ribozyme is such that a cleavage recognition site is located near the 5'end of the mRNA corresponding to the polynucleotide of the invention; ie, it increases efficiency and promotes intracellular accumulation of non-functional mRNA transcripts. Manipulated to minimize.

In the case of the antisense approach, the ribozymes of the invention can be composed of modified oligonucleotides (improved for stability, targeting, etc.) and express the polynucleotides of the invention in vivo. Should be delivered to cells. The DNA construct encoding the ribozyme can be introduced into the cell in the same manner as described above for the introduction of antisense encoding DNA.

Two primers of 0 nucleotides are synthesized and used to amplify the desired cDNA using the deposited cDNA plasmid as a template.

Briefly, specific RNA oligonucleotides are ligated to the 5'end of a population of RNAs that probably contains full-length gene RNA transcripts. PCR of the 5'portion of the desired full-length gene is performed using a primer set containing a primer specific to the linked RNA oligonucleotide and a primer specific to the known sequence of the gene of interest.
Amplify. The amplified product can then be sequenced and used to generate the full length gene.

This above method starts with total RNA isolated from the desired source, but may also use poly A + RNA. The RNA preparation is then treated with phosphatase, if necessary, to degrade or damage the RN, which may interfere with subsequent RNA ligase steps.
The 5'phosphate group of A can be eliminated. The phosphatase should then be inactivated, and the RNA should be treated with tobacco acid pyrophosphatase to remove the cap structure present at the 5'end of the messenger RNA.
This reaction leaves a 5'phosphate group at the 5'end of the cap cleaved RNA that can then be ligated to the RNA oligonucleotide using T4 RNA ligase.

This modified RNA preparation is used as a template for first-strand cDNA synthesis using gene-specific oligonucleotides. First strand synthesis reaction
It is used as a template for PCR amplification of the desired 5'end using primers specific for the ligated RNA oligonucleotide and primers specific for the known sequence of the gene of interest. The resulting product is then sequenced and analyzed to confirm that the 5'end sequence belongs to the desired gene.

If the naturally occurring signal sequence is not used, the vector can be modified to include a heterologous signal sequence (see, eg, WO96 / 34891).

Two days later, the cells are trypsinized and seeded in hybridoma cloning plates (Greiner, Germany) in α-MEM supplemented with 10, 25, or 50 ng / ml methotrexate and 1 mg / ml G418. After about 10-14 days, single clones were trypsinized and then at different concentrations of methotrexate (50 nM, 100 nM, 200 nM, 400 nM, 800 nM).

Clones growing at the highest concentrations of methotrexate are then transferred to new 6-well plates containing higher concentrations of methotrexate (1 μM, 2 μM, 5 μM, 10 mM, 20 mM).

Example 9: Protein Fusions The polypeptides of the invention are preferably fused to other proteins. These fusion proteins can be used in various applications. For example, fusion of a polypeptide of the invention to a His tag, HA tag, protein A, IgG domain, and maltose binding protein facilitates purification (see Example 5; EP.
See also A 394,827; Traunecker et al., Nature.
e, 331: 84-86 (1988)). Similarly, fusions to IgG-1, IgG-3, and albumin increase half-life in vivo. Nuclear localization signals fused to the polypeptides of the invention can target proteins to specific subcellular localizations. On the other hand, covalent heterodimers or homodimers may increase or decrease the activity of the fusion protein. Fusion proteins can also create chimeric molecules that have more than one function. Finally, fusion proteins may increase the solubility and / or stability of fusion proteins as compared to non-fusion proteins. All forms of the above fusion proteins can be made by modifying the protocol below, which outlines the fusion of polypeptides to IgG molecules, or the protocol described in Example 5.

Briefly, the human Fc portion of an IgG molecule can be PCR amplified using primers spanning the 5'and 3'ends of the sequences described below. These primers should also have convenient restriction enzyme sites which facilitate cloning into an expression vector, preferably a mammalian expression vector.

For example, if pC4 (accession number 209646) is used, the human Fc portion can be ligated into the BamHI cloning site. Note that the 3'BamHI site should be destroyed. Then, the vector containing the human Fc portion is transformed into B
The polynucleotide of the invention, which was again restricted with amHI, linearized the vector and isolated by the PCR protocol described in Example 1,
It is linked to the amHI site. Note that the polynucleotide is cloned without a stop codon, otherwise no fusion protein will be produced.

PC4 does not require a second signal peptide if a naturally occurring signal sequence is used to produce the secreted protein. Alternatively, if a naturally occurring signal sequence is not used, the vector can be modified to include a heterologous signal sequence (see, eg, WO 96/34891).

GACTCTAGAGGAT (SEQ ID NO: 1) (Example 10: Production of antibody from polypeptide) The antibody of the present invention can be prepared by various methods. (Current Pr
otocols, Chapter 2). As one example of such a method, cells expressing a polypeptide of the invention are administered to an animal to induce the production of serum containing polyclonal antibodies. In a preferred method, a preparation of secreted protein is prepared and purified to be substantially free of natural contaminants. Such preparations are then introduced into animals to produce greater specific activity of polyclonal antisera.

In the most preferred method, the antibodies of the invention are monoclonal antibodies (or protein binding fragments thereof). Such monoclonal antibodies are prepared using hybridoma technology (Kohler et al., Nature 25.
6: 495 (1975); Kohler et al., Eur. J. Immunol. 6:

ands and T-Cell Hybridomas, Elsevier
, N .; Y. , Pp. 563-681 (1981)). Generally, such a procedure involves immunizing an animal, preferably a mouse, with the polypeptide, or more preferably with a secreted polypeptide-expressing cell. Such cells may be cultured in any suitable tissue culture medium; however, they are preferably supplemented with 10% fetal bovine serum (inactivated at about 56 ° C.), and about 10 g / l of non-essential amino acids, About 1,
It is cultured in Earle's modified Eagle medium supplemented with 000 U / ml penicillin and about 100 μg / ml streptomycin.

Splenocytes of such mice are extracted and fused with a suitable myeloma cell line. Any suitable myeloma cell line may be used in accordance with the present invention; however, AT
It is preferred to use the parental myeloma cell line (SP2O) available from CC. After fusion, the resulting hybridoma cells were selectively maintained in HAT medium and then Wands et al. (Gastroenterology 80: 225-232 (
Cloning by limiting dilution as described by 1981)). The hybridoma cells obtained through such selection are then assayed to identify clones secreting antibodies capable of binding the polypeptide.

Alternatively, additional antibodies capable of binding the polypeptide may be generated using anti-idiotypic antibodies in a two step process procedure. Such a method takes advantage of the fact that the antibody itself is the antigen and therefore it is possible to obtain an antibody that binds to the second antibody. According to this method, protein-specific antibodies are used to immunize animals, preferably mice. The splenocytes of such animals are then used to produce hybridoma cells. The hybridoma cells are then screened to identify antibody-producing clones whose ability of the antibody to bind to the protein-specific antibody can be blocked by the polypeptide. Such antibodies include anti-idiotypic antibodies to protein-specific antibodies and are used to immunize animals to induce the formation of additional protein-specific antibodies.

It is clear that Fab and F (ab ′) 2 and other fragments of the antibodies of the invention can be used according to the methods described herein. Such fragments are typically generated by proteolytic cleavage using an enzyme such as papain (to produce Fab fragments) or pepsin (to produce F (ab ') 2 fragments). To be done. Alternatively, secreted protein-binding fragments may be produced by the application of recombinant DNA technology or synthetic chemistry.

For in vivo use of antibodies in humans, it may be preferable to use "humanized" chimeric monoclonal antibodies. Such antibodies can be produced by using genetic constructs derived from hybridoma cells which produce the monoclonal antibodies described above. Methods for producing chimeric antibodies are known in the art. (For a review, see Morrison, Science 229: 1202.

It is specifically understood that either derived from, or by a polypeptide that induces the expression of other proteins, which are then secreted into the supernatant.
Thus, the invention further provides methods for identifying proteins in supernatants characterized by activity in a particular assay.

Example 12: Construction of GAS Reporter Constructs One signaling pathway involved in cell differentiation and proliferation is Jaks-ST.
Called the AT route. Proteins activated in the Jaks-STAT pathway bind to the gamma activation site "GAS" element or interferon-sensitive response element ("ISRE") located in the promoters of many genes.
Binding of proteins to these elements alters the expression of related genes.

GAS and ISRE elements are recognized by signal transducers and activators of transcription, a class of transcription factors called “STATs”. There are 6 members in the STAT family. S
tat1 and Stat3, as well as Stat2 (as the response to IFNα is widespread) are present in many cell types. Stat4 is more restricted and is not present in many cell types, but is found in T helper class I cells after treatment with IL-12. Stat5, originally called breast growth factor, is found in higher concentrations in other cells, including bone marrow cells. It can be activated in tissue culture cells by many cytokines.

STATs are activated and translocate from the cytoplasm to the nucleus upon tyrosine phosphorylation by a set of kinases known as the Janus Kinase (“Jaks”) family. Jaks represent a unique family of soluble tyrosine kinases and include Tyk2, Jak1, Jak2, and Jak3.
These kinases show significant sequence similarity and are generally catalytically inactive in resting cells.

Jaks are activated by a wide range of receptors as summarized by the table below. (Schidler and Darnell, Ann. Rev. Bi
ochem. 64: 621-51 (1995). Jaks
The cytokine receptor family that is capable of activating sac can be divided into two groups:
(A) Class 1 includes IL-2, IL-3, IL-4, IL-6, IL-7, IL
-9, IL-11, IL-12, IL-15, Epo, PRL, GH, G-CS
F, GM-CSF, LIF, CNTF, and receptors for thrombopoietin; and (b) class 2 includes IFN-a, IFN-g, and IL-.
Including 10. Class 1 receptors contain a conserved cysteine motif (a set of 4 conserved cysteines and 1 tryptophan), and WSXWS.
Shares the motif (membrane adjacent region encoding Trp-Ser-Xxx-Trp-Ser (SEQ ID NO: 2)).

Thus, upon binding of the ligand to the receptor, Jaks is activated, which in turn activates STAT, which then translocates and binds to the GAS element. This entire process is involved in the Jaks-STAT signaling pathway.

Therefore, the Jak reflected by the binding of GAS or ISRE elements
Activation of the s-STAT pathway can be used to indicate proteins involved in cell growth and differentiation. For example, growth factors and cytokines are described in Jaks-S
It is known to activate the TAT pathway. (See table below). Therefore, by using a GAS element linked to a reporter molecule, Jak
Activators of the s-STAT pathway can be identified.

[Table 4] To construct synthetic GAS containing promoter elements used in the biological assays described in Examples 13-14, a PCR-based strategy is used to generate the GAS-SV40 promoter sequence. The 5'primer contains four tandem copies of the GAS binding site found in the IRF1 promoter and previously demonstrated to bind to STAT upon induction with a range of cytokines (Rothman et al. , Immunity 1: 457-
468 (1994)), other GAS or ISRE elements may be used instead. The 5'primer also contains an 18 bp sequence complementary to the SV40 early promoter sequence and flanks the XhoI site. The sequence of the 5'primer is: 5 ': GCGCCTCGAGATTTTCCCCGAAATCTAGATTTTCC

Adjacent to dIII site: 5 ': GCGGCAAGCTTTTTGCAAAG
CCTAGGC: 3 '(SEQ ID NO: 4).

PCR amplification is performed with the SV40 promoter template present in the B-gal: promoter plasmid obtained from Clontech. The resulting PCR fragment is digested with XhoI / HindIII and subcloned into BLSK2- (Stratagene). Sequencing with forward and reverse primers confirms that the insert contains the following sequences:

[0727]

[Chemical 5] When this GAS promoter element is bound to the SV40 promoter,
The GAS: SEAP2 reporter construct is then engineered. Here, the reporter molecule is secretory alkaline phosphatase or "SEAP". However, clearly any reporter molecule can substitute for SEAP in either this or other examples. Well-known reporter molecules that can be used in place of SEAP include chloramphenicol acetyl transferase (C
AT), luciferase, alkaline phosphatase, β-galactosidase, green fluorescent protein (GFP), or any protein detectable by an antibody.

The synthetic GAS-SV40 promoter element identified by the above sequence was added to HindIII and XhoI to generate the GAS-SEAP vector.
Is used to effectively replace the SV40 promoter with the amplified GAS: SV40 promoter element and subcloned into the pSEAP-promoter vector obtained from Clontech. However, this vector does not contain the neomycin resistance gene and is therefore not preferred for mammalian expression systems.

Therefore, in order to generate a mammalian stable cell line expressing the GAS-SEAP reporter, the GAS-SEAP cassette was removed from the GAS-SEAP vector with SalI and NotI and GAS-SEAP / Neo. To create the vector, these restriction sites in the multiple cloning site were used to construct a backbone vector containing the neomycin resistance gene (eg pGFP-1 (C
longtech)). Once the vector is transfected into mammalian cells, the vector can then be used as a reporter molecule for GAS binding as described in Examples 13-14.

Other constructs can be made using the above description and substituting GAS with a different promoter sequence. For example, the construction of a reporter molecule containing NFK-B and EGR promoter sequences is described in Examples 15 and 16. However, many other promoters can be replaced using the protocols described in these examples. For example, the SRE, IL-2, NFAT, or osteocalcin promoters alone or in combination (eg, GAS / NF-KB / EGR, G
AS / NF-KB, Il-2 / NFAT, or NF-KB / GAS). Similarly, other cell lines (eg, HELA (epithelial cells), HUVEC (endothelial cells), Reh (B cells), Saos-2 (osteoblasts), HUVAC (aortic cells), or cardiomyocytes) can be used as reporters. It can be used to test the activity of the construct.

. Then 35 μl of sample from each well is transferred to an opaque 96-well plate using a 12-channel pipette. The opaque plate should be covered (using a cover of cellophane) and stored at -20 ° C until the SEAP assay described in Example 17 is performed. The plate containing the remaining treated cells is placed at 4 ° C. and serves as a source of material for repeating the assay on specific wells, if desired.

As a positive control, 100 units / ml of interferon-γ can be used, which is known to activate Jurkat T cells. Typically,> 30-fold induction is observed in the positive control wells.

The above protocol can be used to generate both transient and stable transfected cells, which will be apparent to those of skill in the art.

Example 15: High Throughput Screening Assay to Identify Neuronal Activity When a cell undergoes differentiation and proliferation, a panel of genes is activated via many different signaling pathways. One of these genes, EGR1 (Early Growth Response Gene 1), is induced in various tissues and cell types upon activation. EG

Example 16: High Throughput Screening Assay for T Cell Activity NF-KB (Nuclear Factor KB) is used in a wide variety of agents (inflammatory cytokines IL-1 and TNF, CD30 and CD40, (Including lymphotoxin-α and lymphotoxin-β), transcription factors activated by exposure to LPS or thrombin, and by expression of specific viral gene products. As a transcription factor, NF-KB expresses genes involved in activation of immune cells, controls apoptosis (NF-KB seems to protect cells from apoptosis),
It regulates B and T cell development, antiviral and antibacterial responses, and multiple stress responses.

In unstimulated conditions, NF-KB is retained in the cytoplasm with I-KB (inhibitor KB). However, upon stimulation, I-KB is phosphorylated and degraded, causing NF-KB to shuttle to the nucleus, thereby activating transcription of target genes. Target genes activated by NF-KB include IL-2, IL-6, GM-CSF, ICAM-1 and class 1.

Example 19: High Throughput Screening Assay to Identify Tyrosine Kinase Activity Protein tyrosine kinases (PTKs) represent a diverse group of transmembrane and cytosolic kinases. Within the receptor protein tyrosine kinase (RPTK) family, there is a range of receptors for mitogenic and metabolic growth factors, including PDGF, FGF, EGF, NGF, HGF and the insulin receptor subfamily. In addition, there is a large RPTK family whose corresponding ligands are unknown. RPTK ligands include primarily secreted low molecular weight proteins, but also membrane-bound and extracellular matrix proteins.

Activation of RPTK by the ligand involves ligand-mediated receptor dimerization, which results in transphosphorylation of the receptor subunit and activation of cytoplasmic tyrosine kinase. As cytoplasmic tyrosine kinase, src family (
Examples include receptor-associated tyrosine kinases of src, yes, lck, lyn, fyn), and non-receptor bound and cytosolic protein tyrosine kinases such as the Jak family. These members include cytokine superfamily (eg, interleukins, interferons, GM
-CSF and leptin).

Due to the wide variety of known factors that can stimulate tyrosine kinase activity, the identification of these novel human secreted proteins that can activate the tyrosine kinase signaling pathway is of interest. Therefore, the following protocol is designed to identify novel human secreted proteins that can activate the tyrosine kinase signaling pathway.

ld) and place the extract at the bottom of each well using house vacuum.
． Filter through a 45 mm membrane. The extracts are collected in a 96 well capture / assay plate at the bottom of the vacuum manifold and immediately placed on ice. To obtain a clarified extract by centrifugation, solubilize with detergent for 5 minutes, then remove the contents of each well and centrifuge at 16,000 xg for 15 minutes at 4 ° C.

The filtered extract is tested for levels of tyrosine kinase activity. Although many methods of detecting tyrosine kinase activity are known, one of the methods is described herein.

Generally, the tyrosine kinase activity of the supernatant is assessed by determining its ability to phosphorylate tyrosine residues on a particular substrate (biotinylated peptide). Biotinylated peptides that can be used for this purpose include PSK1 (cell division kinase cd
and amino acids 6-20 of c2-p34) and PSK2 (corresponding to amino acids 1-17 of gastrin). Both peptides are substrates for a series of tyrosine kinases and are available from Boehringer Mannheim.

The tyrosine kinase reaction is set up by adding the following components in order. First, after adding 10 μl of 5 μM biotinylated peptide, ATP / Mg ²⁺ (
5 mM ATP / 50 mM MgCl ₂ 10 μl, 5 × assay buffer (40
mM imidazole hydrochloride, pH 7.3, 40 mM β-glycerophosphate, 1 mM

BSA) 10 μl, sodium vanadate (1 mM) 5 μl and finally water 5 μl. The components are mixed gently and the reaction mixture is preincubated for 2 minutes at 30 ° C. The reaction is started by adding 10 μl of control enzyme or filtered supernatant.

The tyrosine kinase assay reaction is then stopped by adding 10 μl of 120 mM EDTA and the reaction is placed on ice.

Tyrosine kinase activity is measured by transferring a 50 μl aliquot of the reaction mixture to a microtiter plate (MTP) module and incubating at 37 ° C. for 20 minutes. As a result, streptavidin (streptava)
din) Coat 96-well plate with biotinylated peptide.
Wash MTP module 4 times with 300 μl / well PBS. Next, anti-phosphotyrosine conjugated to horseradish peroxidase (phospotyro).
Sine) antibody (anti-P-Tyr-POD (0.5 u / ml)) (75 μl) is added to each well and then incubated at 37 ° C. for 1 hour. Wash wells as above.

Next, a peroxidase substrate solution (Boehringer Mannheim) was used.
) Add 100 μl and incubate at room temperature for at least 5 minutes (up to 30 minutes). The absorbance of the sample at 405 nm is measured using an ELISA reader. The level of bound peroxidase activity was quantified using an ELISA reader, which reflects the level of tyrosine kinase activity.

Example 22: Method for Detecting Abnormal Levels of Polypeptides in Biological Samples Polypeptides of the invention can be detected in biological samples, and elevated or decreased polypeptide levels are detected. If so, this polypeptide is a marker of a particular phenotype. It is understood that there are numerous detection methods, and therefore one of skill in the art can modify the following assays to suit their particular needs.

For example, an antibody sandwich ELISA is used to detect a polypeptide in a sample, preferably a biological sample. The wells of a microtiter plate are coated with specific antibody at a final concentration of 0.2-10 μg / ml. This antibody is either monoclonal or polyclonal and is produced by the method described in Example 10. The well is blocked so that non-specific binding of the polypeptide to the well is reduced.

The coated wells are then incubated with the polypeptide-containing sample at RT for more than 2 hours. Preferably, serial dilutions of the sample should be used to confirm the results. The plate is then washed three times with deionized or distilled water to remove unbound polypeptide.

Next, 50 μl of the specific antibody-alkaline phosphatase conjugate was added to 25-400 n.
Add at a concentration of g and incubate at room temperature for 2 hours. Plates are washed again three times with deionized or distilled water to remove unbound conjugate.

75 μl of 4-methylumbelliferyl phosphate (MUP) or p-nitrophenyl phosphate (NPP) substrate solution is added to each well and incubated for 1 hour at room temperature. Reactions are measured by microtiter plate reader. A standard curve is constructed using serial dilutions of control samples and the polypeptide concentration is plotted on the X-axis (log scale) and fluorescence or absorbance on the Y-axis (linear scale). A standard curve is used to interpolate the concentration of polypeptide in the sample.

Example 24: Method of Treating Decreased Levels of Polypeptides The present invention relates to a method for treating an individual in need of increasing levels of a polypeptide of the invention in the body, the method comprising: Administering to such an individual a composition comprising a therapeutically effective amount of an agonist of the invention (including a polypeptide of the invention). Furthermore, it is understood that conditions caused by reduced normal or normal expression levels of secreted proteins in an individual can be treated by administering the polypeptides of the invention, preferably in secreted form. Accordingly, the invention also provides a method of treating an individual in need of increased levels of this polypeptide. The method involves administering to such an individual a therapeutic agent comprising an amount of the polypeptide that increases the activity level of the polypeptide in such individual.

For example, a patient with reduced levels of a polypeptide will receive the polypeptide at a daily dose of 0.1-100 μg / kg for 6 consecutive days. Preferably the polypeptide is in secreted form. The exact details of the dosing and formulation-based regimen are:
Provided in Example 23.

Example 25: Method of Treating Elevated Levels of Polypeptides The present invention also relates to a method for treating an individual in need of decreasing levels of a polypeptide of the invention in the body, the method comprising: , Administering a composition comprising a therapeutically effective amount of an antagonist of the invention (including the polypeptides and antibodies of the invention) to such an individual.

In one example, antisense technology is used to inhibit production of a polypeptide of the invention. This technique is one example of how to reduce the levels of polypeptides, preferably secreted forms of the polypeptides, that result from various etiologies such as cancer.
For example, in patients diagnosed with abnormally elevated levels of polypeptide, antisense polynucleotides are administered at 0.5, 1.0, 1.5, 2.0 and 3.0 mg /
Intravenous administration for 21 days at kg / day. If well tolerated, the procedure is repeated after a 7 day washout period. The formulation of this antisense polynucleotide is provided in Example 23.

Example 26 Treatment Method Using Gene Therapy—Ex Vivo One method of gene therapy involves transplanting fibroblasts capable of expressing a polypeptide into a patient. Fibroblasts are generally obtained from a subject by skin biopsy. The resulting tissue is placed in tissue culture medium and divided into small pieces. A blob of tissue is placed on the wet surface of the tissue culture flask and approximately 10 pieces are placed in each flask. The flask is inverted and tightly closed, then left overnight at room temperature. After 24 hours at room temperature, the flask is inverted, the tissue mass remains fixed at the bottom of the flask, and fresh medium (eg,
Ham's F12 containing 10% FBS, penicillin and streptomycin
Medium) is added. The flask is then incubated at 37 ° C for approximately 1 week.

At this point, fresh medium is added and then replaced every few days. After culturing for another two weeks, a monolayer of fibroblasts appears. Trypsinizing this monolayer,
Scale up to a larger flask.

After digestion with RI and HindIII, it is treated with calf intestinal phosphatase.
The linear vector is fractionated on an agarose gel and purified using glass beads.

The cDNAs encoding the polypeptides of the present invention were prepared as described in Example 1 using primers and with appropriate restriction sites and start / stop codons, respectively, and the 5'and 3'terminal sequences, respectively. Can be amplified using PCR primers corresponding to Preferably, the 5'primer contains an EcoRI site and the 3'primer contains a HindIII site. Equal amounts of the Moloney murine sarcoma virus linear backbone and the amplified EcoRI and HindIII fragments are added together in the presence of T4 DNA ligase. The resulting mixture is maintained under suitable conditions for ligating the two fragments. The ligation mixture is then used to transform bacterial HB101. It is then plated on agar containing kanamycin to confirm that the vector has the gene of interest inserted correctly.

Amphotropic pA317 or GP + am12 packaging cells were
Grow to confluent density in tissue culture in Dulbecco's Modified Eagle Medium (DMEM) with 0% Calf Serum (CS), Penicillin and Streptomycin. The MSV vector containing the gene of interest is then added to the medium and the packaging cells are transduced with this vector. At this time, the packaging cells produce infectious viral particles containing the gene (herein, the packaging cells are referred to as producer cells).

Fresh medium is added to the transduced producer cells, which is then harvested from 10 cm plates of confluent producer cells. The spent medium containing infectious viral particles is filtered through a Millipore filter to remove detached producer cells and then used to infect fibroblasts. Media is removed from the subconfluent plates of fibroblasts and quickly replaced with media from producer cells. This medium is removed and replaced with fresh medium. If the virus titer is high, virtually all fibroblasts will be infected and no selection is required. If the titer is very low, it is necessary to use a retroviral vector with a selectable marker such as neo or his. Once the fibroblasts are efficiently infected, the fibroblasts are analyzed to determine if the protein is being produced.

The engineered fibroblasts are then transplanted into the host either alone or after being grown to confluence on Cytodex 3 microcarrier beads.

Example 27 Gene Therapy Using an Endogenous Gene Corresponding to a Polynucleotide of the Invention Another method of gene therapy according to the present invention is the use of endogenous polynucleotide sequences of the invention, eg, in US Pat. No. 5,641,670 (issued June 24, 1997);
International Publication Number WO 96/29411 (Published September 26, 1996); International Publication Number WO 94/12650 (Published August 4, 1994); Koller et al., P.
roc. Natl. Acad. Sci. USA, 86: 8932-8935 (1
989); and Zijlstra et al., Nature, 342: 435-438.
Operably linked to the promoter via homologous recombination, as described in (1989). The method involves activation of a gene that is present in the target cell but is not expressed in the cell or is expressed at a lower level than desired.

A polynucleotide construct is made that contains a promoter and targeting sequence. This target sequence is homologous to the 5'non-coding sequence of the endogenous polynucleotide sequence, which flanks the promoter. The targeting sequence is 5'of the polynucleotide sequence.
Close enough to the ends so that the promoter is operably linked to the endogenous sequence upon homologous recombination. PCR of this promoter and targeting sequence
Can be used to amplify. Preferably, the amplified promoter contains different restriction enzyme sites on the 5'and 3'ends. Preferably, the 3'end of the first targeting sequence contains the same restriction enzyme sites as the 5'end of the amplified promoter, and the 5'end of the second targeting sequence is the 3'end of the amplified promoter. Contains the same restriction sites as.

The amplified promoter and amplified targeting sequence are digested with the appropriate restriction enzymes, followed by treatment with calf intestinal phosphatase. The digested promoter and digested targeting sequence are added together in the presence of T4 DNA ligase. The resulting mixture is maintained under conditions suitable for ligation of these two fragments. The construct is size fractionated on an agarose gel, then purified by phenol extraction and ethanol precipitation.

In this example, the polynucleotide construct is administered as a naked polynucleotide via electroporation. However, the polynucleotide construct may also be administered with a transfection facilitating agent such as liposomes, viral sequences, viral particles, precipitating agents and the like. Such methods of delivery are known in the art.

Once the cells are transfected, homologous recombination will occur and the promoter will be operably linked to the endogenous polynucleotide sequence. This results in expression of the polynucleotide corresponding to the polynucleotide in the cell. Expression can be detected by immunological staining or any other method known in the art.

Fibroblasts are obtained from a subject by skin biopsy. The obtained tissue is DMEM +
Place in 10% fetal bovine serum. Exponentially growing or early stationary phase fibroblasts are trypsinized and rinsed from the surface of the plastic with nutrient medium. An aliquot of cell suspension is removed for counting and the remaining cells are subjected to centrifugation. The supernatant is aspirated and the pellet is mixed with 5 ml of electroporation buffer (20 mM HEPES pH 7.3, 137 mM NaCl, 5 mM K).
Cl, 0.7 mM Na ₂ HPO ₄ , 6 mM dextrose). The cells are recentrifuged, the supernatant aspirated, and the cells resuspended in electroporation buffer containing 1 mg / ml acetylated bovine serum albumin. This final cell suspension contains approximately 3 × 10 ⁶ cells / ml. Electroporation should be performed immediately after resuspension.

Plasmid DNA is prepared according to standard techniques. For example, to construct a plasmid for targeting to the locus corresponding to a polynucleotide of the invention, plasmid pUC18 (MBI Fermentas, Amherst, NY) was constructed.
) Is digested with HindIII. The CMV promoter is amplified by PCR with an XbaI site at the 5'end and a BamHI site at the 3'end. Two non-coding sequences are amplified via PCR: one non-coding sequence (fragment 1) is amplified with a HindIII site at the 5'end and an XbaI site at the 3'end; the other non-coding sequence (fragment). 2) is amplified with a BamHI site at the 5'end and a HindIII site at the 3'end. The CMV promoter and fragments thereof (1 and 2) were cloned into the appropriate enzymes (CMV promoter-XbaI and BamHI; fragment 1-XbaI; fragment 2-B.
amHI) and digested together. The resulting ligation product was HindII
I digested and ligated with HindIII digested pUC18 plasmid.

Plasmid DNA was added to a sterile cuvette (B
io-Rad). Final DNA concentration is generally at least 120μ
g / ml. Then 0.5 ml of the cell suspension (containing approximately 1.5 × 10 ⁶ cells) is added to the cuvette and the cell suspension and DNA solution are gently mixed. Electroporation is performed using a Gene-Pulser instrument (Bio-Rad). The capacitance and voltage are set to 960 μF and 250-300 V, respectively. Increasing the voltage reduces cell survival, but dramatically increases the proportion of viable cells that stably integrate the introduced DNA into their genome. Given these parameters, the pulse time is about 14-2
0 mSec should be observed.

The electroporated cells are maintained at room temperature for about 5 minutes, then the contents of the cuvette are gently removed using a sterile transfer pipette. The cells were placed in a 10 cm dish containing pre-warmed nutrient medium (D containing 15% bovine serum).
MEM) 10 ml directly and incubate at 37 ° C. The next day, the medium was aspirated and replaced with 10 ml of fresh medium and an additional 16-24
Incubate for hours.

The engineered fibroblasts are then injected into the host, either alone or after being grown to confluence on cytodex 3 microcarrier beads. To do. here,
The fibroblasts produce the protein product. The fibroblasts can then be introduced into a patient as described above.

Example 28: Treatment Methods Using Gene Therapy-In Vivo Another aspect of the invention is the use of in vivo gene therapy methods to treat disorders, diseases, and conditions. This method of gene therapy involves the introduction of naked nucleic acid (DNA, RNA, and antisense DNA or RNA) sequences into an animal to increase or decrease expression of the polypeptide. The polynucleotide of the invention may be operably linked to a promoter, or any other genetic element required for expression of the polypeptide by the target tissue. Techniques and methods for such gene therapy and delivery are known in the art, eg, WO 90/11.

The polynucleotide construct is delivered by any method that delivers an injectable substance to cells of an animal, such as injection into the interstitial space of a tissue (heart, muscle, skin, lung, liver, intestine, etc.). obtain. The polynucleotide construct can be delivered in a pharmaceutically acceptable liquid or aqueous carrier.

The term “naked” polynucleotide, DNA or RNA refers to any delivery vehicle (viral sequence, viral particle, liposomal formulation, lipofectin, or lipofectin that acts to assist, facilitate, or facilitate entry into cells. (Including a precipitating agent) is not included. However, the polynucleotides of the invention can also be prepared in liposome formulations (eg, Felgner) that can be prepared by methods well known to those of skill in the art.

The polynucleotide vector construct used in this gene therapy method comprises:
Preferred are constructs that do not integrate into the host genome and do not contain sequences that allow replication. Any strong promoter known to those of skill in the art can be used to drive the expression of DNA. Unlike other gene therapy techniques, one major advantage of introducing a naked nucleic acid sequence into a target cell is the transient nature of polynucleotide synthesis in that cell. Studies have shown that non-replicating DNA sequences can be introduced into cells to provide for the production of desired polypeptides for periods of up to 6 months.

This polynucleotide construct is used to determine the tissue (muscle, skin, brain, lung, liver,
(Including spleen, bone marrow, thymus, heart, lymph, blood, bone, cartilage, pancreas, kidney, gallbladder, stomach, intestine, testis, ovary, uterus, rectum, nervous system, eye, gland, and connective tissue) It can be delivered to the space. The interstitial spaces of this tissue are intercellular fluids, mucopolysaccharide substrates (between reticulum fibers of organ tissue, elastic fibers in the walls of blood vessels or chambers, collagen fibers of fibrous tissue), or connective tissue sheaths. Includes the same matrix within natural muscle cells or in the hiatus of bone. This is likewise the space occupied by circulating plasma and lymphatic fluid of the lymphatic channels. Delivery of muscle tissue to the interstitial space is preferred for the reasons discussed below. They can be conveniently delivered by injection into the tissue containing these cells. They are preferably delivered to and expressed in differentiated, persistent, non-dividing cells, which delivery and expression can be effected on undifferentiated cells or cells that are not fully differentiated (eg, blood stem cells). Or skin fibroblasts). In vivo, muscle cells are particularly competent for their ability to take up and express polynucleotides.

For naked polynucleotide injections, an effective dosage of DNA or RNA is in the range of about 0.05 g / kg body weight to about 50 mg / kg body weight. Preferably, this dosage is about 0.005 mg / kg to about 20 mg / kg, and more preferably about 0.05 mg / kg to about 5 mg / kg. Of course, as the skilled artisan will appreciate, this dosage will vary according to the tissue site of injection. Suitable and effective dosages of nucleic acid sequences can be readily determined by those of ordinary skill in the art and may depend on the condition being treated and the route of administration. The preferred route of administration is by the parenteral route of injection into the interstitial space of tissues. However, other parenteral routes may also be used,
This includes, for example, inhalation of aerosol formulations, especially for delivery to the mucosa of the lungs or bronchial tissues, throat, or nose. In addition, the naked polynucleotide construct can be delivered to the artery during the angioplasty procedure by the catheter used in this procedure.

The dose response effect of injected polynucleotide in muscle in vivo is determined as follows. Appropriate template DNA for the production of mRNA encoding the polypeptide of the present invention is prepared according to standard recombinant DNA methodologies. Mold DN
Either A, which can be either circular or linear, is used as naked DNA or is complexed with liposomes. The mouse quadriceps is then injected with varying amounts of template DNA.

To 5-6 week old female and male Balb / C mice, 0.3 ml of 2.5%
Anesthetize by intraperitoneal injection of Avertin. A 1.5 cm incision is made in the anterior thigh and the quadriceps are visualized directly. Template DNA is placed in a 0.1 ml carrier and injected with a 1 cc syringe through a 27 gauge needle for 1 minute into the knee about 0.5 cm from the distal insertion site of the muscle at a depth of about 0.2 cm. . Sutures are made over the injection site for future localization and the skin is closed with stainless steel clips.

After the appropriate incubation time (eg 7 days), muscle extracts are prepared by cutting out whole quads. Every 5th 15 μm section of an individual quadriceps is histochemically stained for protein expression. The time course for protein expression can be done in a similar fashion except that four animals from different mice are harvested at different times. Persistence of DNA in muscle after injection can be determined by Southern blot analysis after preparation of total cellular DNA and HIRT supernatants from injected and control mice. The results of the above experiments in mice are shown as naked D
NA can be used to extrapolate appropriate dosages and other treatment parameters in humans and other animals.

Animals of any species, including but not limited to sheep, cows and non-human primates such as baboons, monkeys and chimpanzees, can be used to produce transgenic animals. In certain embodiments, techniques described herein or otherwise known in the art are used for expression of a polypeptide of the invention in humans as part of a gene therapy protocol.

Any technique known in the art can be used to generate transgenic clones containing a polynucleotide of the invention (eg, of cultured, quiescent-induced embryonic cells, fetal cells or adult cells). Nuclear Transfer of Cell-Derived Enucleated Oocytes to the Nucleus (Campell et al., Nature 380: 64-66 (1996); Wil
mut et al., Nature 385: 810-813 (1997))).

The present invention provides transgenic animals that carry the transgene in all their cells, as well as animals that carry the transgene in some (but not all) of the cells (ie, mosaic animals or chimeras). To do. The transgene may be as a single transgene or in a concatemer (eg head-to-head tandem or head-to-head).
Multiple copies, such as tail tandem type). This transgene is also described, for example, in the teaching of Lasko et al. (Lasko et al., Proc. Natl. Ac.
ad. Sci. USA 89: 6232-6236 (1992)) and can be selectively introduced into and activated by specific cell types. The regulatory sequences required for such cell type-specific activation depend on the particular cell type of interest, and they will be apparent to those of skill in the art. Targeting of the gene is preferred when it is desired that the polynucleotide transgene be integrated into the chromosomal site of the endogenous gene. Briefly, if such a technique is utilized, a vector containing several nucleotide sequences homologous to the endogenous gene may be used to bind the nucleotide sequence of the endogenous gene via homologous recombination with the chromosomal sequence. And is designed for the purpose of destroying the function of the nucleotide sequence. Transgenes can also be selectively introduced into specific cell types, and thus, for example, Gu et al. (Gu et al. Science 26
5: 103-106 (1994)), the endogenous gene is inactivated only in the introduced cell type. The regulatory sequences required for such cell type-specific inactivation depend on the particular cell type of interest, and they will be apparent to those of skill in the art.

Once a transgenic animal is produced, expression of its recombinant gene can be assayed using standard techniques. Initial screening can be accomplished by Southern blot analysis or PCR techniques to confirm that transgene integration has occurred by analysis of animal tissue. The level of transgene mRNA expression in the tissues of transgenic animals was also determined by Northern blot analysis, in situ hybridization analysis and reverse transcriptase P of tissue samples obtained from the animals.
It can be assessed using techniques including, but not limited to CR (rt-PCR). Samples of transgenic gene expressing tissues can also be evaluated immunocytochemically or immunohistochemically using antibodies specific for the transgene product.

Once founder animals are generated, they can be crossed, inbred, outbred or crossed to generate colonies of particular animals. Examples of such mating strategies include, but are not limited to: Founder outcrosses with more than one integration site to establish another lineage; additive expression of each transgene. By effect, inbreeding of separate strains to produce composite transgenics expressing higher levels of the transgene; a given routine for both enhancing expression and eliminating the need for screening animals by DNA analysis. Hybridization of heterozygous transgenic animals that produce animals homozygous for the site of integration; crossing of separate homozygous strains to generate complex heterozygous or homozygous lines; and to the desired experimental model Mating to place the transgene on a suitable different background.

The transgenic animals of the invention may be used to describe the biological function of the polypeptides of the invention, study conditions and / or disorders associated with aberrant expression, and ameliorate such conditions and / or disorders. It has applications including, but not limited to, animal model systems useful for screening for effective compounds.

Example 30: Knockout Animals Endogenous gene expression was also demonstrated using targeted homologous recombination for gene and / or gene expression.
Alternatively, it can be reduced by inactivating or “knocking out” its promoter (eg, Smithies et al., Nature 317: 230-2).

1 (1989); each of which is incorporated herein by reference in its entirety). For example, a variant of the invention, a non-functional polynucleotide (or completely unrelated DNA) flanked by DNA homologous to an endogenous polynucleotide sequence (either the coding or regulatory region of this gene). Sequence) can be used with or without a selectable marker and / or a negative selectable marker to transfect cells expressing a polypeptide of the invention in vivo. In another embodiment, techniques known in the art are used to make knockouts in cells that contain the gene of interest but do not express it. Insertion of this DNA construct, via targeted homologous recombination, results in inactivation of the targeted gene. Such an approach is particularly suited to the research and agricultural fields where modifications to embryonic stem cells may be used to produce animal progeny that have inactive targeted genes (eg, Thomas and Capecchi 1987 and Thompson 1989). , See above). However, this approach is conventional for use in humans when the recombinant DNA construct is directly administered or targeted to the required site in vivo using appropriate viral vectors, which will be apparent to those skilled in the art. Can be adapted to.

In a further embodiment of the invention, a cell genetically engineered to express a polypeptide of the invention, or a cell genetically engineered to not express a polypeptide of the invention (eg, a knockout), Administer to patients in vivo. Such cells can be obtained from patients (ie, animals, including humans) or MHC compatible donors, and can be fibroblasts, bone marrow cells, blood cells (eg lymphocytes), adipocytes, muscle cells, endothelial cells, etc. Can be included, but is not limited to. The cells can be transformed, for example, by transduction (using a viral vector and preferably a vector that integrates the transgene into the cell genome) or transfection procedures (plasmids, cosmids, YACs, naked DNA, electroporation, liposomes, etc. Endogenous regulation to introduce a coding sequence of a polypeptide of the invention into a cell or to bind to this coding sequence and / or a polypeptide of the invention. To destroy the array
Genetically engineered in vitro using recombinant DNA technology. The coding sequence of the polypeptide of the invention may be placed under the control of a strong constitutive or inducible promoter or promoter / enhancer to achieve expression and preferably secretion of the polypeptide of the invention. Engineered cells that express and preferably secrete a polypeptide of the invention can be introduced systemically into the patient, eg, in circulation or intraperitoneally.

Alternatively, the cells can be incorporated into a matrix and transplanted into the body (
For example, genetically engineered fibroblasts can be transplanted as part of a skin graft); genetically engineered endothelial cells can be transplanted as part of a lymphoid or vascular graft (eg Anderson et al., US Patent) No. 5,399,349 and Mu
See Lligan and Wilson, US Pat. No. 5,460,959. Each of these is hereby incorporated by reference in its entirety).

If the cells to be administered are non-self or non-MHC compatible cells, they may be administered using well known techniques that interfere with the development of a host immune response against this transduced cell. For example, the cells can be introduced in a capsular form, which does not allow the introduced cells to be recognized by the host immune system, while permitting exchange of components with the immediate extracellular environment.

The transgenic and "knockout" animals of the present invention include a detailed description of the biological function of the polypeptides of the present invention, the study of diseases, disorders and / or conditions associated with aberrant expression, and such diseases. , Including, but not limited to, animal model systems useful in screening compounds effective in ameliorating disorders and / or conditions.

Cells expressing XX are administered to the animal to induce the production of serum containing polyclonal antibodies. In a preferred method, a preparation of XXX protein is prepared and purified to be substantially free of natural contaminants. Such preparations are then introduced into animals to produce greater specific activity of polyclonal antisera.

Monoclonal antibodies specific for protein XXX are prepared using hybridoma technology (Kohler et al. Nature 256: 495 (1).

63-681 (1981)). Generally, the animal (preferably a mouse) is XXX
Immunize with the polypeptide, or more preferably with secreted XXX polypeptide expressing cells. Such polypeptide-expressing cells are preferably supplemented with 10% fetal bovine serum (inactivated at about 56 ° C.) in any suitable tissue culture medium and contain about 10 g / l of non-essential amino acids, about 1. Cultured in Earle's modified Eagle's medium supplemented with 1,000 U / ml penicillin and about 100 μg / ml streptomycin.

Splenocytes from such mice are extracted and fused with a suitable myeloma cell line. Any suitable myeloma cell line may be used in accordance with the present invention; however, AT
It is preferred to use the parental myeloma cell line (SP2O) available from CC. After fusion, the resulting hybridoma cells were selectively maintained in HAT medium and then Wands et al. (Gastroenterology 80: 225-232 (
Cloning by limiting dilution as described by 1981)). The hybridoma cells obtained by such selection are then assayed to identify clones secreting antibodies capable of binding XXX polypeptide.

Alternatively, additional antibodies that can bind to the XXX polypeptide can be generated in a two step procedure using anti-idiotype antibodies. Such a method takes advantage of the fact that the antibody itself is the antigen and therefore it is possible to obtain an antibody that binds to the second antibody. According to this method, protein-specific antibodies are used to immunize animals, preferably mice. The splenocytes of such animals are then used to produce hybridoma cells. The hybridoma cells are then screened to identify clones producing antibodies whose ability to bind to XXX protein-specific antibody can be blocked by XXX. Such antibodies include anti-idiotypic antibodies to XXX protein-specific antibodies and are used to immunize animals to induce the formation of additional XXX protein-specific antibodies.

For use in vivo use of the antibody in humans, the antibody is "humanized." Such antibodies can be produced by using genetic constructs derived from hybridoma cells which produce the monoclonal antibodies described above. Methods for producing chimeric and humanized antibodies are known in the art and discussed herein (for a review, Morrison, Science 229: 120).

M13Δ gene III is prepared as follows: M13Δ gene III helper phage does not encode gene III protein. Therefore, phage displaying antibody fragments (phagemids) have greater binding avidity for antigen. During phage morphogenesis, infectious M13Δ gene III particles are made by growing helper phage in cells carrying the pUC19 derivative that supplies the wild-type gene III protein. The culture is incubated for 1 hour at 37 ° C without shaking and then for another hour at 37 ° C with shaking. Centrifuge the cells (IEC-Centra 8,400r

Approximately 10 ¹³ TU of phage are applied to the tubes and incubated for 30 minutes at room temperature with tumbling up and down on a turntable, then left to stand for a further 1.5 hours. The tubes are washed 10 times with PBS 0.1% Tween-20 and 10 times with PBS.
The phages were eluted by adding 1 ml of 100 mM triethylamine and spinning up and down for 15 minutes on a turntable, then 0.5 ml of 1.

Characterization of binders. Phage eluted from the third and fourth round of selection were used to transform E. coli. E. coli HB2151 and soluble scFv are generated from a single colony for the assay (Marks et al., 1991). The ELISA is performed using microtiter plates coated with either 10 pg / ml of the polypeptide of the invention in 50 mM bicarbonate, pH 9.6. ELISA

Or competitive antagonist activity, etc.).

Example 32: Assay for Detecting Stimulation or Inhibition of B Cell Proliferation and Differentiation Generation of a functional humoral immune response was demonstrated between B lineage cells and their microenvironment.
It requires both soluble and cognate signaling. The signal can convey a positive stimulus (which causes cells of the B lineage to sustain programmed development) or a negative stimulus (which directs the cell to block the current-generating pathway). To date, IL-2, IL-4, IL-5, IL-6, IL-7, IL
A number of stimulatory and inhibitory signals have been found to influence B cell responsiveness, including -10, IL-13, IL-14 and IL-15. Interestingly, these signals, which are weak effectors in their own right, can be combined with various costimulatory proteins to induce activation, proliferation, differentiation, homing, resistance, and death in B cell populations.

One of the most studied classes of B cell costimulatory proteins is the TNF superfamily. Within this family, CD40, CD27 and CD30
It has been found to regulate a variety of immune responses with its respective ligands, CD154, CD70 and CD153. Assays that allow the detection and / or observation of proliferation and differentiation of these B cell populations and their progenitor cells show the effects that various proteins may have on these B cell populations in terms of proliferation and differentiation. A valuable tool in making decisions. Listed below are two assays designed to allow detection of differentiation, proliferation, or inhibition of B cell populations and their precursors.

Culture in the presence of either Cowan I (SAC) or immobilized anti-human IgM antibody. Secondary signals such as IL-2 and IL-15 cooperate with SAC and IgM cross-linking to induce B cell proliferation as measured by tritiated thymidine incorporation. New synergists can be easily identified using this assay. This assay involves the isolation of human tonsillar B cells by magnetic bead (MACS) depletion of CD3 positive cells. The resulting cell population is CD45R

Mice were given this treatment for 4 consecutive days, at which point they were sacrificed and various tissues and sera were collected for analysis. Comparison of H & E sections from normal spleen and spleens treated with the polypeptide of the invention results in activity of this polypeptide on spleen cells, such as diffusion of periarterial lymphoid sheaths and / or red pulp regions. A significant increase in nucleated cellularity is noted, which may indicate activation of B cell population differentiation and proliferation. Anti-CD, a B cell marker

Effect on expression of MHC class II, costimulatory molecules and adhesion molecules. Three major families of cell surface antigens can be identified on monocytes: adhesion molecules, molecules involved in antigen presentation, and Fc receptors. Modulation of the expression of MHC class II antigens and other costimulatory molecules such as B7 and ICAM-1 can result in changes in the ability of monocytes to present antigen and to induce T cell activation. Increased Fc receptor expression may be correlated with improved monocyte cytotoxic activity, cytokine release and phagocytosis.

PI uptake has been shown to correlate with DNA fragmentation in this test paradigm.

Effect on Cytokine Release An important function of monocytes / macrophages is their regulatory activity on other cell populations of the immune system through the release of cytokines after stimulation. An ELISA to measure cytokine release is performed as follows.
Human monocytes are incubated at a density of 5 × 10 ⁵ cells / ml with increasing concentrations of a polypeptide of the invention and in the absence of this polypeptide under the same conditions. For production of IL-12, the cells are primed with IFN (100 U / ml) overnight in the presence of the polypeptides of the invention. Then, LPS (10

The selection of cortical cells for bioassays is based on the predominant expression of FGF-1 and FGF-2 in cortical structures and the previously reported enhancement of cortical neuronal survival resulting from FGF-2 treatment.

However, reports from experiments carried out on PC-12 cells indicate that these two responses are not necessarily synonymous, and not only which FGF is being tested, but which receptor is expressed on the target cells. Suggest that you may depend. The ability of the polypeptides of the invention to induce neurite outgrowth can be compared to the response obtained with FGF-2 using the primary cortical neuron culture paradigm, eg, using the thymidine incorporation assay.

Parkinson's Model Loss of motor function in Parkinson's disease results from striatal dopamine deficiency resulting from degeneration of nigrostriatal dopaminergic projection neurons. A widely characterized animal model of Parkinson's disease is 1-methyl-4phenyl 1,2,3
, 6-tetrahydropyridine (MPTP) systemic administration. In the CNS,
MPTP is taken up by astrocytes and 1 by monoamine oxidase B
-Catalyzed and released into methyl-4-phenylpyridine (MPP ⁺ ).
Subsequently, MPP ⁺ is actively accumulated in dopaminergic neurons by the high-affinity reuptake transporter of dopamine. MPP ⁺ is then enriched in mitochondria by an electrochemical gradient and selectively inhibits nicotinamide diphosphate: ubiquinone oxidoreductase (complex I), thereby interfering with electron transfer and To generate active oxygen.

It has been demonstrated in a tissue culture paradigm that FGF-2 (basic FGF) has trophic activity on substantia nigra dopaminergic neurons (Ferrari).
Et al., Dev. Biol. 1989). Recently, Unsicker's group has demonstrated that FGF-2 administration in striatal gel implants results in near complete protection of substantia nigra dopaminergic neurons from toxicity associated with MPTP exposure ( Otto and Unsicker, J. Neuroscience,
1990).

Based on the data using FGF-2, the polypeptide of the present invention exerts a similar action to that of FGF-2 in enhancing the survival of dopaminergic neurons in vitro. Polypeptides of the invention can also be evaluated in vivo to determine if they have, and also tested in vivo for protection of dopaminergic neurons in the striatum from damage associated with MPTP treatment. The potential effects of the polypeptides of the invention are first tested in vitro in the dopaminergic neuronal cell culture paradigm. 14 days pregnant Wista
Cultures are prepared by dissecting the midbrain floor plate from r rat embryos. Tissues were detached with trypsin and seeded on polyortinin-laminin coated coverslips at a density of 200,000 cells / cm ² . The cells are maintained in Dulbecco's modified Eagle medium and F12 medium containing hormone supplements (NI). After 8 days in vitro cultures are fixed with paraformamide and processed for immunohistochemical staining with tyrosine hydroxylase, a specific marker for dopaminergic neurons. Separate cell cultures are prepared from embryonic rats.
The culture medium is changed every 3 days and the factor is also added at each time point.

Since dopaminergic neurons are isolated from animals at day 14 of gestation (this time of development has passed the stage where dopaminergic progenitor cells proliferate), an increase in the number of tyrosine hydroxylase immunopositive neurons was observed in vitro. Shows an increase in the number of surviving dopaminergic neurons. Therefore, it is suggested that if the polypeptide of the present invention acts to prolong dopaminergic survival, this polypeptide may be involved in Parkinson's disease.

Example 50 Diabetic Mice and Glucocorticoid-Injured Wound Healing Model A. Diabetic db + / db + Mouse Models To demonstrate that the polypeptides of the invention promote the healing process, A genetically diabetic mouse model is used. The full thickness wound healing model in db + / db + mice is a well characterized, clinically relevant, and reproducible model of wound wound healing. Healing of diabetic wounds depends on granulation tissue formation and re-epithelialization rather than contraction (Gartner, MH et al., J. Surg. Res. 52: 389 (19).
92); Greenhalgh, D .; G. Et al., Am. J. Pathol. 136
: 1235 (1990)).

This diabetic animal has many of the characteristic properties observed in type II diabetes mellitus. Homozygous (db + / db +) mice have their normal heterozygous (
db + / + m) obese compared to littermates. Mutant diabetic (db + / db +) mice carry a single autosomal recessive mutation (db +) on chromosome 4 (Co

The characteristics observed in these animals indicate that the healing in this model may be similar to that observed in human diabetes (Greenhalgh et al., Am. J. of Pathol. 136: 1235-1246 ( 1990))
.

Genetically diabetic female C57BL / KsJ (db + / db +) mice and their non-diabetic (db + / + m) heterozygous littermates are used in this study (J
acksson Laboratories). Purchased these animals at 6 weeks of age,
And these animals are 8 weeks of age at the start of the study. Animals are housed individually and provided with food and water ad libitum. All operations are performed using aseptic technique. This experiment was performed on Human Genome Sciences, Inc's Insitu

The wound protocol was modified according to previously reported methods (Tsuboi, R. and Rif.
kin, D.M. B. J. Exp. Med. 172: 245-251 (1990)
). Briefly, on the day of wounding, animals were treated with A dissolved in deionized water.
Anesthetize with intraperitoneal injection of vertin (0.01 mg / mL), 2,2,2-tribromoethanol and 2-methyl-2-butanol. The dorsal area of the animal is shaved and the skin is washed with 70% ethanol solution and iodine. The surgical area is dried with sterile gauze before wounding. Then, an 8 mm full-thickness wound
It is prepared using a Keyes tissue punch. Immediately after wounding, the surrounding skin is gently stretched to remove the spread of the wound. The wound is opened during the experiment. The application of treatment is given topically for 5 consecutive days starting from the day of wounding. Prior to treatment, the wound is gently washed with sterile saline and gauze sponge.

The wound is visually inspected and photographed at a fixed distance on the day of surgery and at 2 day intervals thereafter. Wound closure is determined by daily measurements on days 1-5 and 8. Wounds are measured horizontally and vertically using calibrated Jameson calipers. A wound is considered healed when granulation tissue is no longer visible and the wound is covered by continuous epithelium.

The polypeptides of the present invention are administered in the vehicle for 8 days using different dose ranges (4 mg to 500 mg per wound per day). The vehicle control group received 50 mL of vehicle solution.

Animals are euthanized on day 8 with an intraperitoneal injection of sodium pentobarbital (300 mg / kg). The wound and surrounding skin are then collected for histology and immunohistochemistry. Tissue specimens are placed in 10% neutral buffered formalin in a tissue cassette between biopsy sponges for further processing.

Three groups of 10 animals each (5 diabetic and 5 non-diabetic controls) are evaluated: 1) vehicle placebo control, 2) untreated group, and 3) treated group.

Wound closure is analyzed by measuring the area on the horizontal and vertical axes and obtaining the total area of the wound. Contraction is then assessed by establishing the difference between the area of the initial wound (day 0) and the area after treatment (day 8). This wound area on day 1 is 64 mm ² (size corresponding to the skin punch). Calculations are performed using the following formula: [Open area on day 8]-[Open area on day 1] / [Open area on day 1] Specimens are fixed in 10% buffered formalin and paraffin. The embedded mass is cut perpendicular to the wound surface (5 mm) and cut using a Reichert-Jung microtome. Routine hematoxylin-eosin (H & E) staining is performed on transverse sections of bisected wounds. Histological examination of wounds is used to assess whether the healing process and morphological appearance of repaired skin have been altered by treatment with the polypeptides of the invention. This assessment includes verification of the presence of cell accumulation, inflammatory cells, capillaries, fibroblasts, re-epithelialization, and epidermal maturation (Green.

Tissue sections are also immunohistochemically stained with a polyclonal rabbit anti-human keratin antibody using the ABC Elite detection system. Human skin is used as a positive tissue control, while non-immune IgG is used as a negative control.
Keratinocyte proliferation is determined by assessing the extent of wound re-epithelialization using a calibrated lens micrometer.

The rank of these sections is based on the extent of proliferation on a scale of 0-8 (lower scale reflecting slight proliferation to higher side reflecting vigorous proliferation).

Experimental data is analyzed using a one-tailed t-test. A p-value of <0.05 is considered significant.

The wound protocol follows Section A above. On the day of wounding, the animals were given ketamine (5 m
g / kg) and xylazine (5 mg / kg) by intramuscular injection. The dorsal area of the animal is shaved and the skin is washed with 70% ethanol and iodine solution. The surgical area is dried with sterile gauze before wounding. 8 mm full thickness wounds are created using a Keyes tissue punch. The left side of the wound is opened during the experiment. Application of the test substance is given topically once a day for 7 consecutive days, starting from the day of wounding and then methylmethylprednisolone administration. Prior to treatment, the wound is gently washed with sterile saline and gauze sponge.

The wound is visually inspected and photographed at a fixed distance on the day of wounding and at the end of treatment. Wound closure is determined by daily measurements on days 1-5 and on day 8. Wounds are measured horizontally and vertically using a Calibrated Jameson caliper. A wound is considered healed when granulation tissue is no longer visible and the wound is covered by continuous epithelium.

The polypeptides of the present invention are administered in the vehicle for 8 days using different dose ranges (4 mg to 500 mg per wound per day). The vehicle control group received 50 mL of vehicle solution.

Animals are euthanized on day 8 with an intraperitoneal injection of sodium pentobarbital (300 mg / kg). The wound and surrounding skin are then collected for histology. Tissue specimens are placed in 10% neutral buffered formalin in a tissue cassette between biopsy sponges for further processing.

Four groups of 10 animals each (5 with methylprednisolone and 5 without glucocorticoid) are evaluated: 1) untreated group, 2) vehicle placebo control, and 3) treated group. .

Wound closure is analyzed by measuring the area on the vertical and horizontal axes and obtaining the total area of the wound. Closure is then assessed by establishing the difference between the area of the initial wound (day 0) and the area after treatment (day 8). This wound area on day 1 is 64 mm ² (size corresponding to the skin punch). Calculations are performed using the following formula: [Open Area on Day 8]-[Open Area on Day 1] / [Open Area on Day 1] Specimens are fixed in 10% buffered formalin and paraffin. The embedded mass is cut perpendicular to the wound surface (5 mm) and cut using an Olympus microtome. Routine hematoxylin-eosin (H & E) staining is performed on transverse sections of bisected wounds. Histological examination of wounds makes it possible to assess whether the healing process and the morphological appearance of the repaired skin have been improved by treatment with the polypeptides of the invention. A graduated lens observer is used by a blinded observer to determine the gap distance of the wound.

Experimental data is analyzed using a one-tailed t-test. A p-value of <0.05 is considered significant.

The studies described in this example tested polynucleotide activity of the invention. However, one of ordinary skill in the art can readily modify the illustrated studies to test the activity of the polypeptides (eg, gene therapy), agonists, and / or antagonists of the invention.

Example 51: Lymphedema Animal Model The purpose of this experimental approach was to identify lymphangiogenesis (lymph) in the rat hind limb.
to develop a suitable and consistent model of lymphedema for testing the therapeutic effect of the polypeptides of the invention in reestablishing the vascular and lymphatic circulation. Efficacy is measured by swelling volume of the affected limb, quantification of lymphatic vascular mass, total plasma protein mass, and histopathology. Acute lymphedema is observed for 7-10 days. Perhaps more importantly, the chronic progression of edema
Continues for 3-4 weeks.

Prior to beginning surgery, blood samples are drawn for protein concentration analysis.
Male rats (weighing approximately 350 g) are dosed with pentobarbital. Then, the right limb is shaved from the knee to the hip joint. Wipe the shaved area with gauze soaked in 70% EtOH. Blood is drawn for serum total protein testing. After measuring the circumference and volume, mark the two measurement levels (0.5 cm above the heel, midpoint of the back of the foot) and then inject the dye into the foot. On the endothelium of both right and left dorsal
Inject 0.05 ml of 1% Evan's Blue. Then, after the dye is injected into the paw, circumference measurement and volume measurement are performed.

Using the knee joint as a marker, an incision in the groin of the middle limb is made in a ring so that the position of the femoral vessel can be confirmed. The flaps are dissected and separated using forceps and hemostat. After locating the femoral vessel, the lymphatic vessels that run alongside and below the vessel are located. The major lymphatic vessels in this area are then attached to the electrocoagulated suture ligature (ele).

The two proximal lymphatic vessels and two distal lymphatic vessels as well as the distal blood supply of the popliteal node are ligated with sutures. The popliteal lymph nodes and any associated adipose tissue are then removed by cutting connective tissue.

Take care to control any mild bleeding that occurs with this procedure. After occlusion of lymphatic vessels, flaps are placed on the liquid skin (Vetbond) (AJ Buck).
Seal by using. Separate skin edges are sealed to the underlying muscle tissue leaving a gap of about 0.5 cm around the leg. The skin may also be anchored by suturing to the underlying muscle when needed.

To avoid infection, animals are housed individually with mesh (no bedding). Recovered animals are checked daily through the optimal edema peak. This peak typically occurs up to 5-7 days. The plateau edema peak is then observed. To assess the intensity of lymphedema, the circumference and volume of two designated locations on each limb are measured before the procedure and daily for 7 days. The effect of plasma proteins on lymphedema is determined, and it is also investigated whether protein analysis is a useful test perimeter. The weights of both control and edematous limbs are evaluated at two points. The analysis is performed in a blind manner.

Circumference measurement: Under short-term gas anesthesia to prevent movement of the limb, the circumference of the limb is measured using a cloth tape measure. Measurements are made on the talar and dorsal paw by two different persons and then these two readings are averaged. Readings are taken from both control and edematous limbs.

Volumetric: On the day of surgery, animals are anesthetized with pentobarbital and tested prior to surgery. For daily volume measurements, animals are placed under short-term halothane anesthesia (rapid immobilization and quick recovery), both legs shaved, and the legs marked equally with water-resistant markers. The legs are first dipped in water, then dipped into the device to each marked level, then Buxco hydrops software (Chen / Victor
or)). The data is recorded by one person, while the other is soaked in the marked area of the leg.

Blood-Plasma Protein Measurements: Blood is drawn, centrifuged, and serum separated prior to surgery, then the total protein and Ca 2+ comparisons are concluded.

Limb Weight Comparison: Following blood draw, the animals are prepared for tissue collection.
The limb is cut with a quillitine, then both the experimental and control legs are ligated and cut and weighed. A second weighing is performed by removing the tibio-cakaneal joint and weighing the foot.

Histological Preparation: The transverse muscle located behind the knee (popliteal) area was excised and placed in a metal mold, filled with freezeGel, soaked in cold methylbutane and -80EC until cut into labeled sample bags. Place it. Upon cutting, the muscle is observed under the fluorescent microscope for lymphatic vessels.

Example 52 Suppression of TNFα-Induced Adhesion Molecule Expression by Polypeptides of the Invention [1001] The recruitment of lymphocytes to areas of inflammation and angiogenesis is associated with cell surface adhesion molecules (CAM) on lymphocytes. It relates to specific receptor-ligand interactions with the vascular endothelium. This adhesion process is associated with intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-) in both normal and pathological settings.
1), and following a multistep cascade involving endothelial leukocyte adhesion molecule-1 (E-selectin) expression in endothelial cells (EC). Expression of these and other molecules on the vascular endothelium determines the efficiency with which leukocytes can adhere to the local vasculature and overflow into local tissues during the development of the inflammatory response. Local concentrations of cytokines and growth factors are involved in regulating the expression of these CAMs.

Tumor necrosis factor alpha (TNF-α), a potent pro-inflammatory cytokine, is a stimulator of all three CAMs in endothelial cells and may be involved in a wide variety of inflammatory responses, often resulting in disease. Bring physical results.

The potential of the polypeptides of the invention to mediate the suppression of TNF-α induced CAM expression may be tested. A modified ELISA assay, which uses EC as the solid phase adsorbent, was used to quantify the amount of CAM expression in the TNF-α-processed protein EC when co-stimulated with members of the FGF family of proteins. taking measurement.

Processed. After incubation, the cells are then evaluated for CAM expression.

[1005] Human umbilical vein endothelial cells (HUVEC) are grown to confluence in standard 96-well plates. Growth medium is removed from the cells and replaced with 90 μl 199 medium (10% FBS). Samples for testing and positive or negative controls are added to the plate in triplicate (10 μl volume).

Example 53: Assay for Stimulation of Bone Marrow CD34 + Cell Proliferation This assay is based on the ability of human CD34 + to proliferate in the presence of hematopoietic growth factors, and this assay is expressed in mammalian cells. The isolated polypeptides are evaluated for their ability to stimulate proliferation of CD34 + cells.

[1010] The most mature precursors have previously been shown to respond to only a single signal. The more immature precursors require at least two signals to respond. Thus, in order to test the effect of a polypeptide on hematopoietic activity of a wide range of progenitor cells, this assay was performed in the presence or absence of other hematopoietic growth factors.
Contains a given polypeptide. Combining the isolated cells with a test sample,
Culture for 5 days in the presence of stem cell factor (SCF). Only SCF has bone marrow (BM
) It has a very limited effect on the growth of cells and acts only under these conditions as a "survival" factor. However, when combined with any factor that exhibits a stimulatory effect on these cells (eg IL-3), SCF produces a synergistic effect. Thus, if the tested polypeptide has a stimulatory effect on hematopoietic ancestry, such activity can be readily detected. Since normal BM cells have low levels of cell cycle, it appears that no inhibitory effect of a given polypeptide, or its agonists or antagonists, is detected. Therefore, assays for inhibitory effects on ancestors preferably
Tested in cells that are first subjected to in vitro stimulation with CF + IL + 3 and then contacted with the compound being evaluated for inhibition of such induced proliferation.

[1011] Briefly, CD34 + cells are isolated using methods known in the art.
The cells were thawed and cultured in medium (QBSF with 1% L-glutamine.

Determined via Count and printed data collected for analysis. Radioactivity level reflects the amount of cell proliferation.

[1013] The studies described in this example test the activity of a given polypeptide in stimulating bone marrow CD34 + cell proliferation. One of ordinary skill in the art can readily modify the illustrated examples to test the activity of polynucleotides (eg, gene therapy), antibodies, agonists and / or antagonists, and fragments and variants thereof. As a non-limiting example, antagonists that may be tested in this assay are those that inhibit cell proliferation in the presence of cytokines and / or inhibit cell proliferation in the presence of cytokines and certain polypeptides. Is expected to increase. In contrast, agonists that may be tested in this assay are expected to enhance cell proliferation and / or reduce inhibition of cell proliferation in the presence of cytokines and certain polypeptides.

The ability of the gene to stimulate proliferation of bone marrow CD34 + cells indicates that the polynucleotides and polypeptides corresponding to this gene are useful in diagnosis and treatment of disorders affecting the immune system and hematopoiesis. Typical uses are described in the "Immune Reactivity" and "Infectious Diseases" sections above, and elsewhere herein.

Example 54: Assay for Extracellular Matrix Enhanced Cellular Response (EMECR) The purpose of the Extracellular Matrix Enhanced Cellular Response (EMECR) assay is to relate hematopoietic stem cells to extracellular matrix (ECM) induced signals. To identify gene products that act on (eg, isolated polypeptides).

[1016] In response to signals received from the surrounding microenvironment, cells respond to regulatory factors.
For example, fibroblasts, and endothelial and epithelial stem cells are unable to replicate in the absence of signal from the ECM. Hematopoietic stem cells can undergo self-renewal in bone marrow, but not in in vitro suspension culture. The ability of stem cells to undergo self-renewal in vitro depends on their interaction with stromal cells and the ECM protein fibronectin (fn). Adsorption of cells to fn was determined by α ₅ . β ₁ and α ₄ . mediated by the β ₁ integrin receptor,
These receptors are expressed by human and mouse hematopoietic stem cells. EC
The factors responsible for integrating in the M environment and stimulating self-renewal of stem cells have not yet been identified. The discovery of such factors is an important goal in gene therapy and spinal cord transplant applications.

[1017] Briefly, non-polystyrene tissue culture treated 96-well plates were
Coated with fn fragment at a coating concentration of 0.2 μl / cm ² . Mouse bone marrow cells are plated in 0.2 ml serum free medium (1,000 cells / well). The cells cultured in the presence of IL-3 (5 ng / ml) + SCF (50 ng / ml) act as a positive control under conditions where self-renewal of stem cells is not expected and clear differentiation is expected. The gene product is SCF (5.0 ng
/ Ml) with and without an appropriate negative control, where the test factor supernatant represents 10% of the total assay volume. Then
The plated cells are grown by incubating a hypoxic environment _{(5% CO 2, 7%} O 2 and 88% N ₂₎ in the tissue culture incubator for 7 days.
The number of proliferating cells in the wells is then quantified by measuring thymidine incorporation into cellular DNA. Confirmation of positive hits in the assay requires phenotypic characterization of the cells, which characterization can be accomplished by scaling up the culture system and using appropriate antibody reagents for cell surface antigen and FACScan. .

[1018] One skilled in the art can readily modify exemplary studies to test the activity of polynucleotides (eg, gene therapy), antibodies, agonists, and / or antagonists and fragments and variants thereof.

[1019] If a particular gene product is found to be a stimulator of hematopoietic ancestry, then polynucleotides and polypeptides corresponding to this gene may be useful in diagnosis and in the treatment of disorders that affect the immune system and hematopoiesis. possible. Typical applications are the above "
It is described in the section "Immune Activity" and "Infectious Diseases", as well as elsewhere herein. Gene products are also found in various blood chain stem cells and precursor cells.

[1020] Additionally, polynucleotides and / or polypeptides of the gene of interest, and / or agonists and / or antagonists thereof, can also be used to inhibit hematopoietic cell proliferation and differentiation, and thereby chemotherapy. During, it can be used to protect bone marrow stem cells from chemotherapeutic agents. This anti-proliferative effect may allow for the administration of higher doses of chemotherapeutic agents and thus more effective chemotherapeutic treatment.

[1021] Furthermore, polynucleotides and polypeptides corresponding to the gene of interest may also be associated with hematopoietic-related disorders (eg, anemia, pancytopenia, leukopenia, thrombocytopenia,
Or leukemia) may be useful in the treatment and diagnosis. This is because stromal cells are important in the generation of hematopoietic lineage cells. These uses include bone marrow cell ex vivo culture, bone marrow transplantation, bone marrow repopulation, neoplastic radiotherapy or chemotherapy.

[1030] A positive result in this assay is indicative of AoSMC cell proliferation and that the gene product of interest may be involved in skin fibroblast proliferation and / or smooth muscle cell proliferation. A positive result also suggests many potential uses of the gene / gene product of interest polypeptides, polynucleotides, agonists and / or antagonists. For example, inflammation and immune response, wound healing, and angiogenesis, as detailed throughout this specification. In particular, gene product polypeptides and gene polynucleotides can be used for wound healing and skin regeneration, and for promoting angiogenesis (both blood vessels and lymphatic vessels).

Example 56: Expression of Cell Adhesion Molecules (CAM) on Endothelial Cells [1032] The recruitment of lymphocytes to the areas of inflammation and angiogenesis is associated with cell surface adhesion molecules (CAM) on lymphocytes. Includes specific receptor-ligand interactions with the vascular endothelium. The adhesion process follows a multi-step cascade in both normal and pathological environments, which involves intracellular adhesion molecule 1 (ICAM-1), vascular cell adhesion on endothelial cells (EC). Includes expression of molecule 1 (VCAM-1), and endothelial leukocyte adhesion molecule 1 (E-selectin). The expression of these molecules and others on the vascular endothelium determines the efficiency with which leukocytes can adhere to local vasculature and overflow into local tissues during the progression of the inflammatory response. Local concentrations of cytokines and growth factors are involved in regulating the expression of these CAMs.

[1035] Briefly, endothelial cells (eg, human umbilical vein endothelial cells (HUVEC)) grow to confluence in standard 96-well plates. Growth medium was removed from the cells and 100 μl of 199 Medium (10% fetal bovine serum (FBS

Prepare in EGM-2MV with ml bFGF. This assay can be used with a variety of endothelial cells with slightly changed growth media and cell concentrations. Appropriately dilute the dilution of the protein batch to be tested. Serum-free medium without bFGF (GIBCO SFM) was used as an unstimulated control and An
Geostatin or TSP-1 was included as a known inhibition control.

[1035] Briefly, add LEC, BAEC or UTMEC to a 96-well plate in 5 wells.
Seed the growth medium at a density of 000-2000 cells / well and leave at 37 ° C. overnight. After overnight incubation of the cells, growth medium is removed and replaced with GIBCO EC-SFM. The cells are treated with the appropriate dilutions of protein of interest or control protein samples (prepared in SFM) in triplicate wells containing additional bFGF up to a concentration of 10 ng / ml.
Once the cells are treated with the sample, the plate (s) is returned to the 37 ° C. incubator for 3 days. After 3 days, 10 ml of stock Alamar B
lue (Biosource catalog number DAL1100) is added to each well and the plate (s) is placed in a 37 ° C. incubator for 4 days.
Return time. The plate (s) is then read using a CytoFluor fluorescence reader with 530 nm excitation and 590 nm emission. Direct output is recorded in relative fluorescence units.

[1036] Alamar Blue is a redox indicator that fluoresces and discolors in response to chemical reduction of growth medium resulting from cell growth. As the cells grow in the medium, the innate metabolic activity causes a chemical reduction of the immediate environment. Proliferative reduction causes the indicator to change from an oxidized (non-fluorescent blue) form to a reduced (fluorescent red) form. That is, stimulated proliferation produces a stronger signal, and inhibited proliferation produces a weaker signal, and the total signal is proportional to the total number of cells as well as their metabolic activity. Background levels of activity are observed with starvation medium only. This is compared to the output observed from the positive control sample (bFGF in growth medium) and protein dilution.
