| Research Abstract |
DJ-1 has multiple functions, including anti-oxidative stress, and its dysfunction may be linked to the onset of Parkinson's disease. In previous study, we isolated compounds that bind to DJ-1. These compounds prevented oxidative stress-induced cell death via DJ-1. But the action mechanism of DJ-1 binding compounds is unknown. In this study, we examined the effects of compound B, a DJ-1 binding compound on Nrf2 transcriptional activity. Compound B facilitated the H2O2-induced Nrf2 transactivation. Additionally, protein stability of Nrf2 was improved by compound Bwith H2O2. We suggest that DJ-1 and its binding compound B protect against neuronal death through enhancement of oxidative stress-induced Nrf2 transactivation.
