Effect of PCB2 on H2O2-triggered expression levels of related apoptotic proteins. a Expression of Bax and Bcl-2, cytochrome c, caspase-3 were measured by Western blot; b The ratio of Bax/Bcl-2; c Cytochrome c; d Caspase-3. Values are described as the mean ± SD, n = 3. *p < 0.05 compared with untreated control MCF-7 cells, #p < 0.05 compared with H2O2 exposed MCF-7 cells
