Effect of AZC on the expression of Bcl-2 in the hydrogen peroxide induced SH-SY5Y cell toxicity was detected by Western blotting. (a) Representative Western blot showing the levels of total Bcl-2 . (b) Relative density of total Bcl-2 . 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. Bcl-2 : B-cell lymphoma 2; H2O2: 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 62.5 and 125 µg/mL, respectively
