Figure 1From: 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 viability as measured by MTS assay. Cells (1 × 103 per well) were cultured in 96-well plates for 24 h, and treated with indicated concentrations of WA for 72 h. The viable cells were quantified by MTS assay in triplicates.Back to article page
