One study found that thioredoxin-interacting protein (TXNIP), an endogenous inhibitor of reactive oxygen species elimination, regulates Parkin/PINK1-mediated mitophagy in dopaminergic neurons under high-glucose conditions (Su et al., 2020), which revealed the neuronal impact of mitochondrial dysfunction caused by hyperglycemia and hyperglycemia-induced oxidative stress. The gene discussed is PRKN; the disease is Hyperglycemia.
