cu zn-superoxide dismutase and glutathione peroxidase during aging Antioxidant network. SOD Cu/Zn, Cu/Zn superoxide dismutase; GPX, Frontiers | Copper/Zinc Superoxide Dismutase

These pathways involve the production of superoxide by NADPH oxidases, oxidative phosphorylation, glyceraldehyde auto-oxidation, activation of protein kinase C, and the participation of polyol and hexosamine pathways

In 2021, Jung et al., in Korea, investigated whether the oral intake of enzymatically decomposed collagen peptides (acid-processed collagen peptides [APCPs]: 1000 mg suspended in 25-mL samples administered once per day) could improve skin moisture and barrier function by assessing changes in the ceramide and natural moisturizing factor (NMF) contents in the stratum corneum (SC), comparing baseline parameters to end-of-treatment parameter values [37]

The condition is sometimes referred to as juvenile or early onset macular degeneration

These apparently conflicting cases illustrate that individual genes and/or environmental effects may overcome the typical mechanisms and phenotypes observed in FXS
