The effect of HRW treatment on the protein levels of HO-1, SOD-1 and NQO1 in the DRG of animals with neuropathic pain. The levels of HO-1 (A), SOD-1 (B) and NQO1 (C) of CCI-animals treated with VEH or HRW are represented. Sham-operated mice treated with VEH are also shown. Proteins are expressed relative to GAPDH levels Representative blots of HO-1, SOD-1 and NQO1 are shown (D). In all panels, * represents significant differences vs. sham-operated mice treated with VEH and $ vs. CCI-mice treated with HRW (p < 0.05, one-way ANOVA followed by the Bonferroni test). Mean values ± SEM (n = 3 samples per group).
