Master redox regulator Trx1 upregulates SMYD1 & modulates lysine methylation.

ABSTRACT: Thioredoxin 1 (Trx1) is а antioxidant protein that regulates protein disulfide bond reduction, transnitrosylation, denitrosylation and other redox post-translational modifications. In order to better understand how Trx1 modulates downstream protective cellular signaling events following cardiac ischemia, we conducted an expression proteomics study of left ventricles (LVs) after thoracic aortic constriction stress treatment of transgenic mice with cardiac-specific over-expression of Trx1, an animal model that has been proven to withstand more stress than its non-transgenic littermates. Although previous redox post-translational modifications proteomics studies found that several cellular protein networks are regulated by Trx1-mediated disulfide reduction and transnitrosylation, we found tha
