文摘
Echinacea purpurea has been shown to have anti-diabetic activities; for example, it activates peroxisome proliferator-activated receptor γ (PPARγ) and increases insulin-stimulated glucose uptake. Adipogenesis has been used to study the insulin signaling pathway and to screen anti-diabetic compounds. The present study was conducted to investigate the effects of an ethanol extract of E. purpurea (EEEP) and its constituents on the insulin-induced adipocyte differentiation of 3T3-L1 preadipocytes. When adipocyte differentiation was induced with insulin plus 3-isobutyl-1-methylxanthine and dexamethasone, the accumulation of lipid droplets and the cellular triglyceride content were significantly increased by EEEP. The expressions of PPARγ and C/EBPα in adipocytes treated with EEEP were gradually increased as compared with control cells. Fat accumulation and triglyceride content of adipocytes treated with dodeca-2(E),4(E)-dienoic acid isobutylamide were significantly increased as compared with control cells. The expressions of PPARγ and C/EBPα in adipocytes treated with dodeca-2(E),4(E)-dienoic acid isobutylamide were significantly higher than in control cells. These results suggest EEEP promotes the adipogenesis that is partially induced by insulin and that dodeca-2(E),4(E)-dienoic acid isobutylamide appears to be responsible for EEEP-enhanced adipocyte differentiation.
