Figure 3

Cell death of breast cancer cells induced by cucurbitacin B. (a) MCF7:5C, MDA-MB-231, and SKBR-3 were incubated with the indicated doses of cucurbitacin B for 48 hr and apoptosis was analyzed by staining phosphatidylserine translocation with FITC-Annexin V. Annexin V staining is represented on the -axis and PI staining is represented on the -axis. The most representative result of three independent experiments is shown. 5 μM data for MDA-MB-231 are not shown. Simple vertical bars represent the mean apoptosis rate of all of breast cancer cells (b). Results shown are the average of three independent experiments. versus nontreated control; versus nontreated control.
