The effects of ADM, H₂O₂, and GSH on the viability of MCF-7 and MCF-7/ADM cells. Two days after the treatment, the effects of (a) ADM, (b) H₂O₂, and (c) GSH on the viability of MCF-7 and MCF-7/ADM cells were measured by SRB assay. Data represents the mean ± SD, , and significant differences of inhibition relative to control group were indicated as and .
