Fig. 7. (a) Effects of I or VI on cellular mitochondrial membrane potential. MCF-7 cells were treated for 24 or 48 h with IC50 of I or VI. The percentage of cells with hypopolarized mitochondrial membrane potential was determined by Mito-ID® Membrane Potential Kit. Data are the means of five independent experiments. Error bars indicate SD. (b) MCF-7 cells were treated with IC50 of I or VI for 24 h. The amount of p53 was detected by Western blotting analysis as described in the ESI.† .
