Figure 2From: Down-regulation of estrogen receptor-alpha and rearranged during transfection tyrosine kinase is associated with withaferin a-induced apoptosis in MCF-7 breast cancer cells Effect of WA on MCF-7 cell proliferation as measured by Trypan blue exclusion assay. Cells were treated with DMSO or the indicated concentrations of WA for 24 h. A, percentage of viable cells in total cell population; B, the number of viable cells. Data were presented as mean (n = 3) ± SD. *, P < 0.05, significantly different from control by one-way ANOVA.Back to article page
