In Figure 3(a) of the published paper entitled “Cucurbitacin B Causes Increased Radiation Sensitivity of Human Breast Cancer Cells via G2/M Cell Cycle Arrest,” we mistakenly used the same flow cytometry data panel for the MDA-MB231 cells treated with 2.5 𝜇M and 5 𝜇M cucurbitacin B. The corrected figure and legend are presented here.

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 𝑥-axis and PI staining is represented on the 𝑦-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. ∗ 𝑃 < 0.05 versus nontreated control; ∗∗ 𝑃 < 0.01 versus nontreated control.
