Age-Associated Insolubility of Parkin in Human Midbrain is Linked to Redox Balance and Sequestration of Reactive Dopamine Metabolites

Jacqueline M. Tokarew, Daniel N. El Kodsi, Nathalie A. Lengacher, Travis K. Fehr, Angela Nguyen, Bojan Shutinoski, Brian O’Nuallain, Ming Jin, Jasmine M. Khan, Andy Cheuk‐Him Ng, Juan Li, Qiubo Jiang, Mei Zhang, Liqun Wang, Rajib Sengupta, , Michael G. Schlossmacher

This study investigates how parkin's redox state and insolubility in human midbrain relate to oxidative stress and dopamine metabolism, showing that parkin's cysteine modifications affect H2O2 levels and neuroprotection.

Parkinson Disease-Linked Parkin Mediates Redox Reactions That Lower Oxidative Stress In Mammalian Brain

Daniel N. El Kodsi, Jacqueline M. Tokarew, Rajib Sengupta, Nathalie A. Lengacher, Andy Cheuk‐Him Ng, Heather Boston, Qiubo Jiang, Carina Palmberg, Chantal A. Pileggi, Bojan Shutinoski, Juan Li, Angela Nguyen, Travis K. Fehr, Doo Soon Im, Steve M. Callaghan, , Michael G. Schlossmacher

This study shows that parkin reduces oxidative stress in mammalian brains by mediating H2O2 reduction and glutathione regeneration, but its absence leads to increased oxidative stress despite compensatory mechanisms.

Oxidative Modifications of Parkin Underlie its Selective Neuroprotection in Adult Human Brain

Jacqueline M. Tokarew, Daniel N. El Kodsi, Nathalie A. Lengacher, Travis K. Fehr, Angela Nguyen, Brian O’Nuallain, Ming Jin, Jasmine M. Khan, Andy Cheuk‐Him Ng, Juan Li, Qiubo Jiang, Mei Zhang, Liqun Wang, Rajib Sengupta, Kathryn R. Barber, , Michael G. Schlossmacher

This study identifies oxidative modifications of parkin in adult human brain that confer neuroprotection by reducing H2O2, conjugating dopamine radicals, and forming neuromelanin.
