From differential gene expression to differential gene function and backRecent strategies for drug target identification and validation

Abstract

Following the decoding of several plant and animal genomes, the identification of all corresponding transcripts and proteins and understanding how their expression corresponds to physiological and pathological states is the obvious next step. Nucleic acid quantification methods have become increasingly high-throughput and relatively low-cost, and moving ahead, combinations of technologies monitoring differential gene expression and those defining differential cellular function will yield maximum benefit in furthering biology and for drug target identification and validation.
