Resveratrol(RES),a natural polyphenolic phytochemical,has been suggested as a putative anti-aging molecule for the prevention and treatment of Alzheimer’s disease(AD)by the activation of sirtuin 1(Sirt1/Sir2).In this...
The skeletal system is a dynamically balanced system, which undergoes continuous bone resorption and formation to maintain bone matrix homeostasis. As an important ADP-ribosylase and NAD+-dependent deacylase, SIRT6 (S...
Mammalian Sirtuins are the homologs of yeast Saccharo myces cerevisiae Sir2 (silent information regulator 2) which functions in chromatin silencing to prevent genomi~ instability and aging by catalyzing the histone ...
