Fig. 3. Expressions of EZH2 and E2F1 in DU 145 cells. WB assay shows decreases of EZH2 and E2F1 expressions after docetaxel treatment (A). Using knockdown of E2F1, the expressions of E2F1 and EZH2 are decreased (B), and TRAIL (100 ng/mL) treatment causes significant cell death in siE2F-1 DU 145 cells (***p<0.001) (C). DR4: death receptor 4, DR5: death receptor 5, EZH2: enhancer of zeste homolog 2, ns: not significant, TRAIL: tumor necrosis factor-related apoptosis-inducing ligand, WB: western blot.
