Western blots of dopamine transporter (DAT), mu opioid receptor 1 (mOR1) and cannabinoid receptor 1 (CB1) protein levels. DAT (a) and mOR1 (b) levels did not differ between WT and α-DB KO mice in the prefrontal cortex (PfCtx), nucleus accumbens (nAc), caudate-putamen (Cpu) or Tegmentum (Tegmtm). However, CB1 expression (c) was upregulated in the PfCtx and downregulated in the nAc of α-DB KO mice relative to WT mice. Numbers represent the molecular weight markers (kDa). Black lines represent non-continuous lanes loaded on the same gel. n = 7/group, *p < 0.05, two-way ANOVA with Sidak’s post-hoc
