Viability (MTT assay) of SH-SY5Y cells pretreated with Thymoquinone-rich fraction (TQRF) and Thymoquinone (TQ) for 24 h and subsequent exposure to 250 μM H2O2 for 3 h. (a) TQRF + 250 μM H2O2, (b) TQ (μg/mL) + 250 μM H2O2, and (c) 1% TQ in TQRF (ng/mL) + 250 μM H2O2. Results are the mean ± SD. In each panel, mean values labeled with different alphabets are significantly different at .
