WebReactive oxygen species (ROS) are produced in cells during metabolic processes. Excessive intracellular ROS may react with large biomolecules, such as DNA, RNA, proteins, and small biomolecules, that is, glutathione (GSH) and unsaturated fatty acids. WebFeb 25, 2024 · Thioredoxin-interacting protein (Txnip) is an additional member of the Trx1 system, which negatively regulates Trx function ( Arnér, 2009; Mustacich and Powis, 2000 ). In the GSH/Grx system, by contrast, glutathione reductase (Gsr) maintains the pool of cellular GSH in its reduced state, which in turn further reduces oxidized Grx ( Lu, 2013 ).
Web14) or thioredoxin-binding protein-2 (TBP-2) (15), inhibits thi-oredoxin antioxidative function by binding to its redox-active cysteine residues (15, 16). We show here the inhibition of the thioredoxin ROS-scaveng-ing system through induction of Txnip in hyperglycemia.
