Effects of FBE and specific fractions on the expression of adipogenesis-related transcription factors. 3 T3-L1 preadipocytes were incubated with DMSO (0.1%) or 5 μg/ml of NBE, fractions F1, F2, F2-3 and pure compounds CAT (3 μg/ml), CA (5 μg/ml) and induced to differentiate. PPARγ a and SREBP-1c b expression levels were examined by Western blot. Protein expressions were normalized using β-actin as a reference. Results are shown as the mean ± SEM. Significantly different compared to DMSO control *p < 0.05, **p < 0.01
