(a) Western blotting detection of mitochondria-mediated apoptosis-related proteins: Bax, Bcl-2, Caspase-3, and p53 expression levels; (b) analysis of Bax/Bcl-2 ratio, Caspase-3, and p53 expression in HepG2 cells treated with PBPs of 0, 62.5, and 125 μg/mL, respectively (∗P < 0.05/∗∗P < 0.01 versus control).
