Outline of Final Research Achievements

To identify the molecules related vulnerability of dopaminergic neurons to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) neurotoxicity of NDUFV2 heterozygous knockout mice, I performed high throughput molecular profiling using isobaric tags for relative and absolute quantitation (iTRAQ) and liquid chromatography tandem mass spectrometry (LC-MS/MS) analyses. A total of 17 proteins were identified as statistically different between wild-type and NDUFV2 heterozygous knockout mice in the midbrain of 48 hours after the MPTP administration. This results raise the possibility of discovering novel proteins related the pathogenesis of Parkinson’s disease (PD).
To analyze molecular phenotypes of CHCHD2, which have been reported as a novel causative gene for autosomal dominant PD, I generated CHCHD2 knockout SH-SY5Y cells using CRISPR-Cas9 system. CHCHD2 knockout SH-SY5Y cell was markedly decreased protein levels and activity of cytochrome c oxidase (Complex IV).
