Effects of FoxM1 depletion on cell growth. A , FoxM1 mRNA levels were down-regulated by FoxM1 siRNA. B , FoxM1 protein levels were down-regulated by siRNA. C , Inhibition of cancer cell proliferation by FoxM1 siRNA tested by MTT assay. D , Inhibition of cancer cell colony formation capacity by FoxM1 siRNA. Experiments were repeated at least three times, and representative data are presented; bars, SD.*, P < 0.05; **, P < 0.01, relative to control.
