MicroRNAs (miRNAs) are an abundant class of 22-nucleotide (nt) noncoding RNAs, some
of which are known to control the expression of other genes at the posttranscriptional level (1–…

Although microRNAs (miRNAs) are among the most intensively studied molecules of the past
20 years, determining what is and what is not a miRNA has not been straightforward. Here, …

A portion of five vertebrate species microRNA (miRNA) genes are found to associate with
CpG-islands. It is calculated that 74 of 462 (16.0%), 37 of 373 (9.9%), 25 of 234 (10.7%), 25 of …

Using a homology search based on genomic survey sequence analysis and microRNA (miRNA)
secondary structure, a total of 51 miRNA genes encoding 30 amphioxus miRNAs were …

MicroRNAs (miRNAs) are a large class of small RNAs that function as negative gene
regulators in eukaryotes. They regulate diverse biological processes, and bioinformatics data …

Background MicroRNAs have been identified as crucial regulators in both animals and
plants. Here we report on a comprehensive comparative study of all known miRNA families in …

Noncoding miRNAs tend to evolve within introns of coding genes who provide them with
transcriptional opportunity. As an outcome of natural selection, the intragenic position of …

Small regulatory RNAs have recently emerged as key regulators of eukaryotic gene expression.
Here we used high-throughput sequencing to determine small RNA populations in the …

MicroRNA (miRs) are short non-coding RNAs that fine-tune the regulation of gene expression
to coordinate a wide range of biological processes. MicroRNAs are transcribed from miR …

Sexual dimorphism depends on sex-biased gene expression, but the contributions of microRNAs
(miRNAs) have not been globally assessed. We therefore produced an extensive small …
