Expressions of transcription factors C/EBP β and PPARγ, adipogenic proteins including adipsin D and perilipin, were increased significantly (Fig. 7, p < 0.05); In expressions of apoptotic proteins, Bcl-2 were decreased, Bax and active caspaes-3 were increased significantly (Fig. 8, p < 0.05) in a dose-dependent manner in both of morusin treated breast cancer cells and tumor tissues compared with the controls. This evidence concerns the gene PPARG and breast cancer.
