Expression of arrestin2 protein (A) and mRNA (B) and arrestin3 protein (C) and mRNA (D) in the striatum of control subjects and subjects with Parkinson's disease (PD) or with Parkinson's disease and dementia (PDD). Bar graphs show the results of quantitative analysis of Western blots as means±S.E. The data were statistically analyzed separately for individual brain regions by one-way ANOVA with Group (control, PD, PDD) as main factor followed by Bonferroni/Dunn post hoc test. * - p<0.05, ** - p<0.01 to control; # - p<0.05; & - p<0.01 to PD group.
