FOXM1 alters the microtubule dynamics in preventing docetaxel induced apoptosis. Polymerized and soluble tubulin fractions from docetaxel untreated and treated FOXM1-siRNA and pcDNA3, 1-FOXM1 transfected cell lines were generated by centrifugation. Western blot was used to assay α-tubulin and β-tubulin ratios in polymerized and soluble fractions. (A) Relative percentages are shown above western blot. (B) The soluble to polymerized microtubule fractions after docetaxel treatment were significantly inhibited in FOXM1 overexpressed group, analyzed by t test both for α-tubulin and β-tubulin. **, P ≤ 0.01; ***, P ≤ 0.001 significant.
