Nrf2/ARE signaling is related to the neuroprotective and antioxidant effects mediated by PCs. (a) Knockout efficiency was detected by determination of Nrf2 protein expression using Western blotting; (b) Nrf2/GAPDH protein relative expression (ratio to control); (c) Cell viability; (d) MDA levels; (e) SOD activity. F and p values of the one-way analysis of variance are presented above each chart. The results of Tukey’s post hoc test are presented for selected comparisons: ns, p > 0.05; *, p < 0.05; **, p < 0.01; ***, p < 0.001; the error bars are SD.
