Effect of naringin on rotenone-induced apoptotic features in SH-SY5Y cells pretreated with 10 µM rotenone for 24 h. Naringin (10 µM) was treated 4 h prior to rotenone treatment. Condensed chromatin was stained dark brown (lower). Scale bar, 100 µm. Three independent experiments were performed for this study.
