Effect of AZC on hydrogen peroxide induced cytotoxicity in SH-SY5Y cells. (a) Light microscopy of SH-SY5Y cell morphology at 40x magnification. (b) % cell viability of SH-SY5Y cells. Data are presented as mean ± SEM. ^aaap < 0.001; compared to naïve control, ^{*, **}p < 0.05 and 0.01, respectively; compared to SH-SY5Y cells treated with hydrogen peroxide, and which had received the vehicle. hydrogen peroxide: hydrogen peroxide at dose of 200 µM; AZC low dose and AZC high dose: the anthocyanin-rich extract derived from Zea mays L. var. ceratina at doses of 31.25 and 62.5 µg/mL, respectively
