Expression of P-Bcl-2 (Ser70), PARP, and cleaved caspase-3 was analyzed employing western blot and relevant antibodies. Actin was used as a loading control. Data of one representative experiment out of three independent experiments shown. (B) Densitometric analysis of P-Bcl-2 (Ser70), cleaved form of PARP, and cleaved caspase-3. Data expressed as fold change of the respective control cells after 24 h and 72 h of treatment. The mean ± SD of three independent experiments shown. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
