WebThioredoxin reductase 2 (TXNRD2) is a mitochondrial protein encoded by the TXNRD2 gene on chromosome 22. Variants in the TXNRD2 gene have been associated with POAG in … WebThe severity of brain injury and neurological deficits were measured by histological quantification and forelimb asymmetry test, respectively. The role of thioredoxin (Trx) in E2-mediated neuroprotective effect was examined by intrastriatal administration of a Trx reductase inhibitor, 5,5-dithiobis-(2- nitrobenzoic acid), and small interfering RNA.
