Specifically, the DEGs were significantly associated with pathways including Parkinson’s disease, selenocompound metabolism, protein-disulfide reductase activity, oxidoreductase activity acting on a sulfur group of donors, glutathione metabolism, mitochondrial matrix, cellular detoxification, cellular oxidant detoxification, antioxidant activity, and cell redox homeostasis (Figure 2C). Here, TXNRD1 is linked to Parkinson disease.
