The anti-obesity effects of extracts of Inonotus obliquus and roasted I. obliquus were investigated through the measurement of the differentiation of 3T3-L1 pre-adipocytes to adipocytes. Cytotoxic activity was determined by MTT assays on 3T3-L1 pre-adipocyte. Adipocyte differentiation was assessed through the evaluation of lipid accumulation (by using Oil Red O staining) and the expression of adipogenic proteins (by using western blotting). Compared with the control, the treatment of differentiating adipocytes with extracts of I. obliquus , and roasted I. obliquus significantly inhibited differentiation. In the presence of an adipogenic cocktail (isobutyl- methylxanthine, dexamethasone, and insulin), I. obliquus and roasted I. obliquus extracts significantly decreased the expression of adipogenic proteins, peroxisome proliferator-activated receptor-γ (PPARγ), and CCAAT/enhancer binding protein alpha (C/EBP-α), relative to the expression level of N-acetyl-L-cystein (NAC, negative control). These results indicated that the extracts of I. obliquus and roasted I. obliquus were potential candidates for the prevention obesity.
