The Importance of Thioredoxin (Trx) and Glutathione-Glutaredoxin (GSH/Grx) Systems in Terms of Aging
Öz
Oxidative stress results from an imbalance between the production of free radicals, such as reactive oxygen species (ROS) and reactive nitrogen species (RNS), and the body's ability to counteract their harmful effects. This imbalance can lead to cellular damage, contributing to the development of aging and various aging-related diseases, such as cardiovascular disease, neurodegenerative disorders, and cancer. ROS are produced by cellular sources such as the endogenous mitochondrial respiratory chain, the cytochrome P450 system's detoxification of xenobiotics, and the phagocytes' nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX) and myeloperoxidase (MPO) killing of bacteria. These ROS are generated by both endogenous and exogenous sources and are protected against by enzymatic antioxidant systems, including superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), thioredoxin (Trx), and glutathione-glutaredoxin (GSH/Grx) systems, as well as non-enzymatic antioxidant systems like GSH, urate, and coenzyme Q10. Apart from providing antioxidant defense, the Trx and GSH/Grx systems also play roles in thiol-based redox signaling and redox homeostasis. Thiol-based cysteine modifications mediated by redox signals, including S-glutathionylation, S-nitrosylation, and S-sulfhydration, can be reversed by Trx and GSH/Grx systems. Trx, TrxR, and Grx may also alter cellular senescence and lifetime through their interactions with different signaling pathways and transcription factors. These systems' important properties may increase interest in them in the near future. Understanding the complex interactions between the Trx and GSH/Grx systems might help develop novel anti-aging novel treatment strategies that increase cellular resilience and longevity.
