Emodin Augments Cisplatin Cytotoxicity in Platinum-Resistant Ovarian Cancer Cells via ROS-Dependent MRP1 Downregulation

Figure 5

Expression of MRP1 mRNA in COC1/DDP cells exposed to cDDP or emodin. RT-PCR analysis was performed to assess MRP1 mRNA levels expressed as the fold change relative to that in the untreated control cells after normalization to GAPDH. Values are mean ± S.D. of three separate experiments performed in duplicate. versus cDDP-only treated cells; versus the 30 μM DDP + 50 μM emodin cotreated cells.
