Sirtuins: guardians of mammalian healthspan.

Abstract excerpt

The first link between sirtuins and longevity was made 15 years ago in yeast. These initial studies sparked efforts by many laboratories working in diverse model organisms to elucidate the relations between sirtuins, lifespan, and age-associated dysfunction. Here, we discuss the current understanding of how sirtuins relate to aging. We focus primarily on mammalian sirtuins SIRT1, SIRT3, and SIRT6, the three...
