What role does Transferrin play in Wechseljahre?

The rs4880 variant in the SOD2 gene affects mitochondrial antioxidant capacity, as SOD2 is a key enzyme for neutralizing superoxide radicals in mitochondria. However, a direct causal link to accelerated wrinkle formation is not established. Skin aging is predominantly driven by environmental factors such as UV exposure, smoking, and diet. Evidence for rs4880 and skin aging comes from mechanistic and observational studies, not from randomized controlled trials. The effect size is small, and this SNP alone has no clinical predictive power. What can you do? General measures against oxidative stress – antioxidant-rich diet, consistent sun protection, avoiding smoking – are beneficial but not specific to rs4880. Do not be misled by DNA tests into taking unnecessary supplements; a blood test for oxidative stress or nutrient deficiency would be more informative. In summary, rs4880 is a weak, mechanistically plausible marker, but no cause for alarm or drastic changes.
