Antioxidant Enzymes

The core of selenoprotein research is to clarify how redox reactions involving selenocysteine affect antioxidant defense, mitochondrial homeostasis, inflammatory responses, and cell death. Combined detection of selenoproteins such as GPX, TXNRD, and SELENOP with SOD, CAT, PRDX, GSH/GSSG, ROS, ...

The antioxidant enzyme defense system is an important barrier by which cells resist reactive oxygen species-induced damage. Superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px/GPx) form a continuous reaction chain that removes superoxide anions, hydrogen peroxide, and ...

The skin is chronically exposed to multiple oxidative environments, including ultraviolet radiation, air pollution, ozone, visible light, and endogenous metabolic stress. The key to maintaining cutaneous homeostasis does not lie in a single antioxidant ingredient, but in a continuous defense ...
