Effect of naringin on rotenone-induced cell death in SH-SY5Y cells. (A) MTT cell viability assay at 0.1, 1, 5, 10, and 20 µM rotenone for 24 h in SH-SY5Y cells. (B) Naringin inhibits rotenone-induced cytotoxicity in SH-SY5Y cells, treated with 10 µM rotenone for 24 h. Naringin (1, 5, and 10 µM) was added 4 h before rotenone treatment. Independent experiments were repeated three times. Values are presented as mean±SEM. Con, control. ^*p<0.05 compared to non-treated cells; ^†p<0.05 compared to rotenone-treated cells.
