Abstract

Signaling from the DAF-2/insulin receptor to the DAF-16/FOXO transcription factor controls longevity, metabolism, and development in disparate phyla. To identify genes that mediate the conserved biological outputs of daf-2 /insulin-like signaling, we usedcomparative genomics to identify 17 orthologous genes from Caenorhabditis and Drosophila , each of which bears a DAF-16 binding site in the promoter region. One-third of these DAF-16 downstream candidate genes were regulatedby daf-2 /insulin-like signaling in C. elegans , and RNA interference inactivation of the candidates showed that many of these genes mediate distinct aspects of daf-16 function, including longevity, metabolism, anddevelopment.
