Apoptotic effects of hesperetin in PC3 cells. Apoptosis induced by hesperetin was analyzed by flow cytometry using dual staining with propidium iodide and fluorescein isothiocyanate-conjugated Annexin V in PC3 cells. (a) Control without treatment, (b-d) the cells were treated with 400, 450, and 500 μM of hesperetin, respectively
