Bach1 derepression is neuroprotective in a mouse model of Parkinson's disease. Proc Natl Acad Sci U S A. 2021 Nov 9;118(45):e2111643118. doi: 10.1073/pnas.2111643118.

Parkinson's disease (PD) is a progressive neurodegenerative movement disorder characterized by the loss of nigrostriatal dopaminergic neurons. Mounting evidence suggests that Nrf2 is a promising target for neuroprotective interventions in PD. However, electrophilic chemical properties of the canonical Nrf2-based drugs cause irreversible alkylation of cysteine residues on cellular proteins resulting in side effects. Bach1 is a known transcriptional repressor of the Nrf2 pathway.
