Downregulation of TMPO inhibited the proliferation of GBM cells. a, b Cell proliferation in U251 and U87 cells after TMPO-shRNA infection was determined by MTT assay, respectively. c The proliferation of U251 cells was examined after TMPO-shRNA(S2) infection by MTT assay. d Representative microscopic images of colonies in TMPO-shRNA- or TMPO-shRNA(S2)-infected U251 cells were stained by crystal violet. e Statistical analysis of the number of colonies. **p < 0.01, ***p < 0.001; scale bars, 25 μm
