Mitochondrial membrane potential (MMP) analysis by rhodamine 123 assays. After treatment of the series with Huaier extract, the MMP of both (a) MDA‐MB‐231 and (b) MCF‐7 cells decreased in a time‐ and dose‐dependent manner. The mean fluorescence intensity is shown on each graph and presented as mean ± SD of three independent experiments. con, control.
