Serum glutathione peroxidase

Glutathione peroxidase (GSH-Px or GPX) is one of the important free-radical trapping enzymes in the body. Studies have shown that free radicals are closely related to tumor pathogenesis. GSH-Px not only has the effect of scavenging free radicals and derivatives, but also reduces the formation of lipid peroxides and enhances the body's ability to resist oxidative damage. GSH-Px also participates in the synthesis of prostaglandins (PGI2) and thromboxane (TXA2), protecting the structure and function of cells. Therefore, the role of GSH-Px in cellular antioxidant defense mechanisms is receiving increasing clinical attention.
