A role for SIR-2.1 regulation of ER stress response genes in determining C. elegans life span

ABSTRACT: This SuperSeries is composed of the following subset Series: GSE4093: Resveratrol treatment of daf-16 mutant C. elegans GSE4094: N2 worms treated with Resveratrol GSE4095: Sir-2.1 low copy transgenic Abstract: C. elegans SIR-2.1, a member of the Sir-2 family of NAD(+)-dependent protein deacetylases, has been shown to regulate nematode aging via the insulin/IGF pathway transcription factor daf-16. Treatment of C. elegans with the small molecule resveratrol, however, extends life span in a manner fully dependent upon sir-2.1, but independent of daf-16. Microarray analysis of worms treated with resveratrol demonstrates the transcriptional induction of a family of genes encoding prion-like glutamine/asparagine-rich proteins involved in endoplasmic reticulum (ER) stress response to unfolded pr
