Sci. Aging Knowl. Environ., 23 June 2004 NEWS FOCUSLow-Cal ConnectionsCalorie restriction might harness life-span extension protein to stop cell suicideMary Beckman http://sageke.sciencemag.org/cgi/content/full/2004/25/nf60Abstract: Less food can mean more protein--a specific protein, that is. The life-prolonging regime of calorie restriction (CR) boosts quantities of SIRT1, a potential mammalian longevity molecule, new research shows. The protein protects cells by blocking stress-induced suicide, suggesting that CR lengthens animals' lives at least in part by preserving irreplaceable cells. The results hint that several seemingly disparate life-extending methods overlap. Citation: M. Beckman, Low-Cal Connections. Sci. Aging Knowl. Environ. 2004 (25), nf60 (2004).
