Effect of different concentrations of Plumbagin on HCT15 and HT29 cell proliferation.

<p><i>a. HCT15 cells. b. HT29 cells</i>. Proliferation of HCT15 cells treated with 15 µM and 30 µM of plumbagin and HT29 cells treated with 75 µM plumbagin increased significantly at 48 h and 72 h, whereas , 50 µM plumbagin treated HT29 cells tend to proliferate. All the experiments were done in triplicates and expressed as the mean ± SD. Significance is indicated as *<i>p<0.001</i>.
