Figure 4. Effect of BC on apoptosis regulatory proteins in TP-treated BPH rats model. (A) The protein levels of Bcl-2 gene family and (B) pro-caspase-3 and pro-caspase-8 were determined via western blot using specific antibodies in prostatic tissue lysates. β-actin served as an internal control. Densitometric analysis on each protein was performed and relative protein levels were represented as mean ± SD. P value ### = P < 0.001 versus Con group; *** = P < 0.001 versus the BPH group.
