Calorie restriction might harness life-span extension protein to stop cell suicide

Abstract: 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.
