The English-language neologism omics informally refers to a field of study in biology ending in -omics, such as genomics, proteomics or metabolomics. The related suffix -ome is used to address the objects of study of such fields, such as the genome, proteome or metabolome respectively. Omics aims at the collective characterization and quantification of pools of biological molecules that translate into the structure, function, and dynamics of an organism or organisms.

Functional genomics aims at identifying the functions of as many genes as possible of a given organism. It combines different -omics techniques such as transcriptomics and proteomics with saturated mutant collections.

The suffix -ome as used in molecular biology refers to a totality of some sort; it is an example of a "neo-suffix" formed by abstraction from various Greek terms in -ωμα, a sequence that does not form an identifiable suffix in Greek.

Origin

The Oxford English Dictionary (OED) distinguishes three different fields of application for the -ome suffix:

OMICS Publishing Group is a publisher of open access journals that is widely regarded as predatory. It is part of the OMICS Group, based in Hyderabad, India. It issued its first publication in 2008. According to a 2012 article in The Chronicle of Higher Education about 60 percent of the group's 200 journals had never actually published anything.

Academics and the United States government have questioned the validity of peer review by OMICS journals, the appropriateness of author fees and marketing, and the apparent advertising of the names of scientists as journal editors or conference speakers without their knowledge or permission. As a result, the U.S. National Institutes of Health does not accept OMICS publications for listing in PubMed Central and sent a cease-and-desist letter to OMICS in 2013, demanding that OMICS discontinue false claims of affiliation with U.S. government entities or employees. OMICS has responded to criticisms by avowing a commitment to open access publishing, claiming that detractors are traditional subscription-based publishers who feel threatened by their open access publishing model, and threatening a prominent critic with a US$1 billion lawsuit.
