In 1996, Jeff Trent and colleagues published the first paper describing DNA microarrays as tools for pinpointing gene variants underlying various tumor properties.1 Now, as president and scientific director of Translational Genomics Research Institute (TGEN), in Phoenix, Trent is using microarrays to look for gene expression patterns that can be applied to developing diagnostics. The role of microarrays, Trent says, "will be on the discovery side. Testing all 30,000 genes against a diagnosti
