Figure 4. Effect of DMA and imipramine treatment on the survival of paclitaxel-resistant PC3-R cells. PC3-R cells were treated with (A) DMA (5-20 µg/mL) or (B) imipramine (5-20 µg/mL) for 24-72 h and analyzed for cell viability in the MTT assay. Data are presented as mean ± SEM (n = 5 replicates per group). **P < 0.005, ***P < 0.0005; ****P < 0.0001.
