Low Blood Levels of Selenium, Selenoprotein P and GPx3 are Associated with Accelerated Biological Aging: Results from the Berlin Aging Study II (BASE-II)

Abstract

Introduction Biological age reflects inter-individual differences in biological function and capacity beyond chronological age. Biological age can be estimated by DNA methylation age (DNAmA) and its deviation from chronological age, DNAmA acceleration (DNAmAA). Low levels of serum selenium, selenoprotein P (SELENOP), and the selenocysteine-containing glutathione peroxidase 3 (GPx3) are associated with adverse health outcomes and selenium supplementation is discussed as an anti-aging intervention.
