This Week in Cell

University of Massachusetts researcher Albertha Walhout and colleagues describe diet-related gene expression networks delineated multiple genetic screening methods. The group used a mutagenesis screen, RNA interference, and other approaches to track down a gene network involved in dietary response when Caenorhabditis elegans worms munch on Comamonas bacteria rather than their standard Escherichia coli fare.
