Artemisinin inhibits growth and colony forming ability of estrogen receptor positive breast cancer cells. (A) Viability assay in MCF10A, MCF-7, T47D and MDA-MB-231 breast cancer cells showing the effect of artemisinin treatment in a dose and time dependent manner where artemisinin concentration is indicated in X axis and percentage viability compared to control is indicated on the Y axis. The mean + SEM for three independent experiments was calculated. Statistically significant difference was found between the absorbance of control and artemisinin treated samples ***p (<0.001), **p (<0.0078) and ns p (>0.05). B (I) Representative image of colony forming assay of artemisinin treated MCF10A, MCF-7, T47D and MDA-MB-231 breast cancer cells. (II) Graph represents mean + SEM of control, and treated samples in three separate experiments performed in triplicate, *p(<0.05), ***p (<0.001)
