Figure 3From: Platycodin D from Platycodonis Radix enhances the anti-proliferative effects of doxorubicin on breast cancer MCF-7 and MDA-MB-231 cellsEffects of DOX, PD, and DOX + PD on PARP protein expression in breast cancer cells. MCF-7 (A) and MDA-MB-231 (B) cells were incubated with 5 μM DOX, 10 μM PD, or 5 μM DOX + 10 μM PD for 24 h. Then, the cells were collected and their PARP protein expression was measured by western blot analysis.Back to article page
