Abstract:

Vitexin, a bioactive compound isolated from hawthorn leaf extracts, has been reported to exhibit many biological activities, such as anticancer, antioxidation, and adipogenesis inhibition activities. The current study explored the effects of vitexin on high fat diet (HFD)-induced obesity/adipogenesis in male C57BL/6J mice and 3T3-L1 adipocytes, as well as the underlying mechanisms thereof. Vitexin significantly mitigated HFD-induced body weight gain and adiposity. Vitexin also partially normalized serum, hepatic lipid contents, and decreased adipocyte size induced by the HFD. Consistently, there were significant effects of vitexin on important regulators of lipid metabolism, including AMP-activated protein kinase-α (AMPKα), CAATT element binding protein-α (C/EBPα), and fatty acid synthase (FAS) in white adipose tissue. Moreover, vitexin significantly inhibited fat accumulation in 3T3-L1 adipocytes, and this was totally abolished by compound C (an AMPKα inhibitor). These results suggest that vitexin mayprevent HFD-induced obesity/adipogenesis via the AMPKα mediated pathway.
