ABSTRACT
Objective To explore the possible molecular mechanism of Ginsenoside Rg1 preventing against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)-induced substantia nigra neurons apoptosis in Parkinson disease(PD) mouse model. Methods C57BL mice were administrated(sc) with MPTP to produce PD mouse model.Different doses of Rg1(5.0,10.0,20.0*!mg/kg) were given(ip) prior 3*!d to MPTP in the pretreatment groups.Nissl staining,tyrosinehydroxythase(TH) immunostatining,cleaved caspase-3 immunostatining and TUNEL staining were used to observe the changes of nigra neurons,meanwhile,Western blot was used to detect the phosphorylated protein of JNK and c-Jun in substantia nigra. Results Pretreatment with Rg1 could prevent the loss of Nissl staining neurons and TH-positive neurons,inhibit JNK and c-Jun phosphorylation in SN,decrease the percent of cleaved caspase-3 and TUNEL-positive cell.Conclusion Rg1 can attenuate MPTP-induced apoptosis in substantia nigra neurons through blocking JNK signaling cascade.
