By contrast, little is known about genes that normally act to delay aging and that when mutated cause premature aging (progeria). To seek such genes, we performed a genetic screen for C. elegans mutants that age prematurely. We found that loss-of-function mutations of the ketoacyl thiolase gene kat-1 result in an increased accumulation of the lipofuscin-like fluorescent aging pigment, shortened lifespan, early behavioral decline, and other abnormalities characteristic of premature aging. These findings suggest that kat-1 acts to delay C. elegans aging. kat-1 encodes a conserved metabolic enzyme that catalyzes the last step of fatty acid oxidation and was previously shown to regulate fat accumulation in worms. We observed that kat-1 is required for the extension of lifespan and enhanced thermotolerance mediated by extra copies of the deacetylase gene sir-2.1. kat-1 acts independently of other known pathways that affect longevity. Our findings suggest that defects in fatty acid oxidation can limit lifespan and accelerate aging in C. elegans and that kat-1-mediated fatty acid oxidation is crucial for overexpressed sir-2.1 to delay aging."xsd:string |
