EPE-induced apoptosis in JU77 cells. NCI-H28 and JU77 cells were treated with increasing concentration of EPE (200 µg/mL EPE200; 300 µg/mL EPE300). After 48 h, cells were labelled with Annexin V-Alexa Fluor 488 and PI. The results are the mean value of the total apoptotic cells (the sum of early and late apoptotic cells) from three independent experiments ± SD, * p < 0.05 compared to control.
