ANXA5 and posterior cortical atrophy: To evaluate the synergistic effect of resveratrol and docetaxel on apoptosis, PCa cell lines were treated with 47μM (RES), 10nM (DTX), 20μM +10nM (RES+DTX) for C4-2B and 35μM (RES), 31nM (DTX), 22μM+10nM (RES+DTX) for DU145 for 48 h and upon treatment, cells were stained with Annexin V-FITC and PI and analyzed by FlowJo software version 10.2.
