Curcumin inhibits PCa cell proliferation, migration and invasion, and regulates apoptosis-related proteins. (A) BrdU assay was used to detect the proliferation of PCa cells treated with 30 µmol/l curcumin for 24 h (magnification, x400). (B) Wound healing (magnification, x400) and (C) Transwell assays were used to detect the of migration and invasion of PCa cells treated with 30 µmol/l curcumin for 24 h (magnification, x400). (D) Western blotting was used to detect the effect of curcumin on the expression of apoptosis-related proteins. ^**P<0.01, ^***P<0.001 vs. Control. PCa, prostate cancer.
