FoxM1 regulated the proliferative ability of PC-3 cells. PC-3 cells were transfected with FoxM1 overexpression plasmid and small interference RNA. a The FoxM1 overexpression effect was evaluated by Western blot. b The CCK-8 assay result showed that the PC-3 cells’ proliferative ability was increased in FoxM1 overexpression group compared with control. c Ki-67 protein level was increased in FoxM1 overexpression cells by Western blot. d The interference effect was evaluated by Western blot. e The CCK-8 assay result showed that the PC-3 cells’ proliferative ability was decreased in FoxM1 knock down group compared with control. f Ki-67 protein level was decreased in FoxM1 silencing cells.
