Suppression of NPM by shRNA in HeLa cells leads to downregulation of ARF and FOXM1 proteins. A. The protein levels of FOXM1, ARF and NPM following transient NPM knockdown by lentiviral transduction in HeLa human cervical cancer cell line were determined by immunoblotting. β-Actin was used as the loading control. B. The band intensities of FOXM1, ARF and NPM proteins were quantified by densitometry using the Image J gel analysis tool. Columns, mean of three experiments; bars, SD;
