SIRT1 (Sirtuin type 1) is NAD+ dependent histone deacetylase, which plays a variety of physiological functions through acetylation modifing on lysine residue of histone. SIRT1 regulates metabolism and improves metabolic disorder by increasing lipolysis and reducing fat accumulation,by increasing gluconeogenesis and maintaining normal blood glucose lev- els, by increasing insulin sensitivity and improving insulin resistance, by decreasing proteolytic enzymes activity and reducing loss of skeletal muscle mass. Therefore, it is one of the methods for treatment various diseases to increasing S1RT1 activity in human being. Exercise is effective to promote SIRT1 expression and activity. Small molecules polyphenols are activators of SIRT1. Low intengity laser irradiation increase SIRT1 activity. These methods have been widely used in many diseases prevention and treatment.
