RESUMEN
Aim To study the effect of echinacoside on behavior and proteins expression from substantia nigra and striatal tissue in MPTP mouse model of Parkinsons disease(PD)and discover the mechanism of its potential dopaminergic neuroprotective effect in the protein level.Methods The mouse model of PD was induced by 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)and the behavioral analysis of C57BL/6 mice was performed by using spontaneous movement and rotarod test.A proteomic approach based on 2-dimensional electrophoresis(2-DE),mass spectrometry(MS)and figure analysis was used to evaluate the effect of echinacoside on the behavior and the protein expression in substantia nigra and striatal tissue in C57BL/6 mice after MPTP administration.Results ① Compared with control,MPTP lesion significantly reduced the number of spontaneous movement and latent period of mice on the rotating rod(both P
