Aging: it's SIRTainly possible to restore mitochondrial dysfunction

Curr Biol. 2014 Mar 3;24(5):R206-8. doi: 10.1016/j.cub.2014.01.027.

Abstract

Mitochondrial dysfunction is strongly associated with aging. A recent study shows that reduced nuclear SIRT1 activity initiates age-related mitochondrial decline through a signaling pathway that perturbs expression of genes encoded by mitochondrial DNA. This reversible pathway has potential anti-aging therapeutic value.
