(B, C) Quantitative analyses of Nrf2, HO-1, and NQO-1 in each group. (D) Real-time PCR analysis for HO-1 and NQO-1 expression. (E) Representative photomicrographs of double immunofluorescence staining for Nrf2 and NeuN. (F) Quantification of Nrf2 immunofluorescence staining. Bars represent the mean ± SEM. *P < 0.05; ns, not significant.
