Abstract
Omics has become the new mantra in molecular research. “Omics” technologies include genomics, transcriptomics, proteomics and metabolomics. Genomics had revealed the static sequences of genes and proteins and focus has now been shifted to their dynamic functions and interactions. Transcriptomics, proteomics and metabolomics reveal the biological function of the gene product. The “-omic-” technologies are high-throughput technologies and they increase substantially the number of proteins/genes that can be detected simultaneously to relate complex mixtures to complex effects in the form of gene/protein expression profiles. The primary aim of omic technologies is the nontargeted identification of all gene products (transcripts, proteins, and metabolites) present in a specific biological sample. The powerful “omics” technologies have opened new avenues towards biomarker discovery, identification of signaling molecules associated with cell growth, cell death, cellular metabolism and early detection of cancer. Omics will not only have an impact on our understanding of biological processes, but the prospect of more accurately diagnosing and treating disease will soon become a reality.
