Effect of Sub5 on the expression of Bcl-2 family proteins (a), intrinsic apoptotic proteins (b), and extrinsic apoptotic proteins (c) in HepG2 cells. The cells were incubated with subfraction 5 (24 h, 0 to 400 μg/mL) or fluorouracil (5-FU) (25 μg/mL), and the levels of protein expression were investigated by immunoblot analysis. and represent significantly different results at and , respectively, from the untreated cells.
