[Effects of visfatin gene polymorphisms on glycolipid metabolism and exercise-induced weight reduction in obesity].

Visfatin, also named nicotinamide phosphoribosyl transferase (NAMPT), is a cytokine secreted from adipose tissue. Visfatin can regulate immune action and is involved in the NAD+ salvage pathway. In addition, recent researches have shown that visfatin helps the regulation of glucose and lipid metabolism, especially in exercise-induced weight reduction for obesity. The aim of this review is to provide an overview of the contribution of visfatin gene polymorphisms to glucose and lipid metabolism and exercise-induced weight reduction in obesity.
