Omics publication trends 1999–2019. The numbers of publications including genomics, transcriptomics, proteomics, metabolomics, lipidomics, and glycomics approaches have steadily increased in the last two decades, linearly from 1999 to 2009 and exponentially thereafter. Results culminated from PubMed keyword searches of “genomics,″ “transcriptomics,” “proteomics,” “metabolomics” (and “metabonomics”), “lipidomics,” and “glycomics” and limited to appearance in publication title or abstract. Genomics and transcriptomics publications are combined because these approaches rely on sequencing technologies. Metabolomics, lipidomics, and glycomics publications are also combined because comprehensive analysis of these molecular types typically rely on mass spectrometry (MS) approaches but often involve other technology (such as nuclear magnetic resonance spectroscopy).
