Dorsal root ganglia expression of MOR in WT, NOS1-KO and NOS2-KO mice. Relative mRNA (A) and protein (B) expression of MOR in the ipsilateral dorsal root ganglia from sham-operated or sciatic nerve-injured WT, NOS1-KO and NOS2-KO mice. Data are expressed as mean values ± SEM (4-5 samples per group). For each genotype, * P < 0.05 denotes significant differences between sciatic nerve-injured and sham-operated mice (Student's t test). For each experimental group, different letters (a, b) denote significant differences between genotypes (P < 0.05; one way ANOVA followed by the Student Newman Keuls test).
