The overwhelming dominance of ROS generated by enzymes like NADPH oxidases and xanthine oxidase over antioxidants like superoxide dismutase causes cell injury and tissue damage through direct injury, lipid peroxidation and protein oxidation leading to protease release and antioxidant and antiprotease enzyme inactivation as well as alteration of transcription factors activator protein-1 and NFB
Because tirzepatide activates the GIP receptor in addition to the GLP-1 receptor that semaglutide targets, it produces a broader metabolic effect, including stronger appetite suppression, improved insulin sensitivity, and enhanced fat oxidation
Prx3 homodimer has a redox-sensitive cysteine that upon reaction with H 2 O 2 is oxidized to Cys-SOH, which then reacts with neighboring Cys-SH of the other subunit to form an intermolecular disulfide that can be readily reduced by thioredoxin reductase 2 (TrxRD2
The increased expression of GSTA4-4 was also confirmed by Western blot analysis as shown in Figure 14b
