Decreased TH in both PDD and DLB but increased α-synuclein in DLB in CP. a Multivariate analysis of post-mortem samples from TC by western blot. Twenty micrograms of protein were used per well for SDS-PAGE. Blots were cropped from different gels. Representative western blot images were shown. Statistical results of relative protein levels for DAT (b), DD2R (c), and TH (d). e Multivariate analysis of post-mortem samples from CP by western blot. Twenty micrograms of protein were used per well for SDS-PAGE. Blots were cropped from different gels. Representative western blot images were shown. All blot images with significant changes were included in the Additional file 1: Fig. S2. Statistical results of relative protein levels for TH (f) and α-synuclein (α-syn) (g). Protein values are normalized to β-actin levels and control samples. Data are presented as the mean  ±  SEM. Kruskal–Wallis test was used to measure the differences between Control, PDD, and DLB samples. *p  < 0.05, **p  < 0.01. Sample numbers, Control  = 9, PDD  = 9–10, and DLB  = 9
