Abstract:
Objective To investigate the pathogenetic mechanism of ubiquitin-proteasome dysfunction in a model of Parkinson's disease(PD),which can provide the theoretical basis for PD.Methods After establishment of PD model induced by PSI in PC12 cells,proteins of untreated(DMSO) and PSI-treated PC12 cells were extracted 36 h after incubation,and then the maps of the extracted proteins were established by DIGE system.The altered protein spots were identified with MALDI-TOF Pro MS and database searching.Results Thirty-six treatment of PC12 cells with PSI induced the appearance of cytoplasmic Lewy body-like eosinophilic inclusions and apoptosis.The percentage of apoptotic cells was 25.53%.ERp29 were identified by MALDITOF Pro MS.The expression of ERp29 decreased in treatment group,compared with normal group(P
