Figure 1. Effect of WS on viability of breast cancer MDA-MB-231 cells. The bars represent the mean ± standard deviation of six 24-h treatments for the vehicle and different concentrations of WS. The results are statistically significant (P < 0.05) compared to the DMSO-treated (control) cells as determined by one-way ANOVA with Dunnett's test. WS: Withania somnifera; ANOVA: Analysis of variance; DMSO: Dimethyl sulfoxide
