Calorie restriction activates stress-based longevity pathway

Evelyn Strauss;2003/19/nf10

Abstract: New work on yeast indicates that glucose restriction goads a protein without previously known antiaging talents to activate a longevity pathway. The protein, Pnc1p, acts through an enzyme called Sir2p that slows aging in several organisms, and the new results suggest an unexpected means of controlling Sir2p: with the small molecule nicotinamide. The work also supports the notions that glucose restriction activates a stress-response longevity pathway and that hormesis can counteract aging.
