Expression levels of FOXM1 in ovarian cancer cells. A Expression levels of FOXM1 proteins in ovarian cancer cells detected by western blot. Levels of tubulin were evaluated as an internal control for loading. B RT-PCR analysis of FOXM1 mRNA expression levels in ovarian cancer cells. Β-actin was amplified as a control. C Expression levels of FOXM1 mRNA in ovarian cancer cells detected by real-time PCR. The mRNA expression levels were normalized against GAPDH. Columns mean derived from at least three independent experiments, bars, SD. Statistical analysis was done using Student’s t tests. ***P < 0.001, significant.
