glutathione reductase activity gout antioxidant pathway mediated by in response to Mitochondrial Glutathione in Cellular Redox

Both free iron and labile iron, including non-transferrin-bound iron, catalyze the formation of ROS via the Fenton and HaberWeiss reactions, which can impact hepatic mitochondrial, microsomal, and lysosomal function [80,81,82]

1) Biomarker challenges: Classical ferroptosis markers (MDA, 4-HNE, and C11-BODIPY) are non-specific, as they are also generated by other oxidative stress pathways (e.g., ROS from mitochondrial dysfunction)

Cells with an impaired ability to scavenge ROS are expected to be less resistant to an oxidative insult, including one of extracellular origin
