Effects of genetic depletion of DYN on MA-induced dopaminergic change. a Effects of dorsal striatum. b Effects of nucleus accumbens. c Effects of ventral midbrain. Sal = saline, MA = methamphetamine 35 mg/kg, i.p., GRe = ginsenoside Re 20 mg/kg, i.p., Nor-B = Nor-binaltorphimine 3 or 6 mg/kg, i.p., L733 = L-733,060 5 or 10 mg/kg, i.p., WT = wild type, DYN KO = prodynorphin knockout. Each value is the mean ± SEM of six animals (two-way ANOVA followed by Fisher’s LSD pairwise comparisons)
