C elegans longevity
WebAbstract. We report here the first genome-wide functional genomic screen for longevity genes. We systematically surveyed Caenorhabditis elegans genes using large-scale RNA interference (RNAi), and found that RNAi inactivation of 89 genes extend C. elegans lifespan. Components of the daf-2/insulin-like signaling pathway are recovered, as well … WebNov 7, 2008 · These results suggest a link between C. elegans fat metabolism and longevity. Abalance of fat storage and mobilization is a universal feature of animal physiology ( 1 ). Reproduction is an energy-intensive process, which is modulated by the availability of nutrients and in turn influences lipid metabolism ( 2 ).

WebC. elegans for aging research. For research on aging, early studies in C. elegans focused on the feasibility of measuring lifespan and the use of 5-Fluoro-2′-deoxyuridine (FUDR) to maintain synchronous cultures of aged animals (Hosono Citation 1978a, Citation 1978b).In 1977, Klass (Citation 1977) published that C. elegans was a good system for aging … WebJul 14, 2016 · Autophagy genes are required in the intestine for the longevity of dietary-restricted eat-2 mutants.
