The inducible co-activator PGC-1a plays a crucial role in adaptive thermogenesis and increases energy expenditure in brown adipose tissue (BAT).Meanwhile,chronic inflammation caused by infiltrated-macrophage in the white adipose tissue (WAT) is a target for the treatment of obesity.Bofutsushosan (BF),a traditional Chinese medicine composed of 17 crude drugs,has been widely used to treat obesity in China,Japan,and other Asia countries.However,the mechanism underlying anti-obesity remains to be elucidated.In the present study,we demonstrated that BF oral administration reduced the body weight of obese mice induced by high-fat diet (HFD) and alleviated the level of biochemical markers (P ＜ 0.05),including blood glucose (Glu),total cholesterol (TC),triglyceride (TG),low density lipoprotein (LDL-C) and insulin.Our further results also indicated that oral BF administration increased the expression of PGC-1α and UCP1 in BAT.Moreover,BF also reduced the expression of inflammatory cytokines in WAT,such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6).These findings suggested that the mechanism of BF against obesity was at least partially through increasing gene expression of PGC-1α and UCP1 for energy consumption in BAT and inhibiting inflammation in WAT.
