Figure 2. High ER-α36 expression enhances pterostilbene-induced apoptosis in breast cancer cells.

Figure 2

a. Apoptosis induction in Mb231, Mb231/Si36, MCF-7, and MCF-7/ER36 cells treated with 30 µM pterostilbene for 72 h was analyzed through flow cytometry (X-Axis: Annexin V; Y-Axis: Propidium iodide, PI). The apoptosis rates are presented as both early and late apoptotic cells compared to total cells. b. Statistical analysis of FACS in (a). c. Caspase-3 expression in the two paired cells after control and 30 µM pterostilbene treatment for 72 h. (Means ± SE, **p<0.01).
