Effect of cadmium, quercetin and their simultaneous treatment on the expression of dopamine receptors in the corpus striatum of rats. Cadmium exposure decreased mRNA (A) and protein (B) expression of DA-D2 receptors in the corpus striatum while simultaneous treatment with quercetin protected cadmium-induced changes. β-actin was used as a housekeeping gene in qRT-PCR studies and as a loading control in western blotting. The cropped gels are displayed for the clear representation. Values are mean ± SEM of three rats in each group; Significantly differs (*p < 0.05, **p < 0.01); a-compared to control group; b-compared to cadmium exposed group.
