| Outline of Final Research Achievements |
DJ-1, the product of the causative gene of a familial form of Parkinson’s disease (PD), undergoes preferential oxidation at the cysteine residue at position 106 (Cys-106) under oxidative stress. In the present study using specific antibodies against Cys-106-oxidized DJ-1 (oxDJ-1), we evaluated oxDJ-1 levels in brain and blood of PD patients. It was found that DJ-1 oxidation in erythrocytes and in the brain occurs in PD patients, particularly during the early phases. DJ-1 oxidation was effectively inhibited by endogenous antioxidant glutathione. We could develop the molecular base for the diagnosis and treatment of PD at early phases based on the levels of oxDJ-1.
