(A) 14 day CCB02 treatment of MDA-MB-231, HCC827-GR, Calu-6 and MCF10A (+Dox, extra centrosomes) mostly eliminated cells with extra centrosomes. At the end of the treatment, cells were fixed and stained for centrosomes. Bar graph shows the percentage of cells displaying two- and more than two centrosomes. 'Vehicle' at the bar graph indicates percentages of cells with extra centrosome Note that percentages of cells containing more than two centrosomes are significantly reduced upon CCB02-treatment (open bars). Data represent mean ± SEM of three independent experiments. (N)=3, (n=70). p values were obtained using unpaired t test **P < 0.001, ***P < 0.0001
