Skin-aging research examining how oxidative damage to an antioxidant enzyme could link cellular protein quality decline to tissue-level aging. Open this review to see the lines of evidence and hypotheses researchers weigh.
Key Takeaways
- Oxidative modification of SOD1 undermines its antioxidant activity and can promote SOD1 misfolding and toxic species formation within skin cells.
- Accumulating ROS and oxidized SOD1 create a self-reinforcing cycle linking mitochondrial dysfunction, proteostasis collapse, and cellular senescence.
- Proteostasis failure driven by ROS and SOD1 dysfunction likely contributes to extracellular-matrix remodeling and functional skin aging outcomes like wrinkles and reduced elasticity.
