Figure 1. TRIM expression was decreased in PD patients, PD mice and cells. (A) TRIM3 mRNA expression in venous blood samples of 53 patients with PD was reduced. (B and C) MPTP-HCl injection prominently decreased TRIM3 mRNA and protein expression in the mice midbrain with a time-dependent manner. (D) MPP+ treatment dramatically reduced cells viability with a dose-dependent manner. (E) MPP+ treatment significantly decreased TRIM3 protein expression in SH-SY5Y cells with a dose-dependent manner. (F) MPP+ treatment obviously reduced the number of TH positive expression dopaminergic neurons in the mice midbrain with a time-dependent manner. * P < 0.05 and ** P < 0.01 relative to Sham group or Control group.
