Curcumin inhibits PCa cell viability and promotes apoptosis. (A) Cell Counting Kit-8 was used to detect the viability of PCa cells treated with different concentrations of curcumin for different times. Flow cytometry was used to detect the apoptosis rates of PCa cells (B) treated with 0-50 µmol/l of curcumin for 24 h and (C) treated with 30 µmol/l curcumin for different times. ^*P<0.05, ^**P<0.01, ^***P<0.001 vs. 12 h or Control; ^#P<0.05, ^##P<0.01, ^###P<0.001 vs. 24 h. PCa, prostate cancer.
