Anti-aging and anti-carcinogenic effects of 1α, 25-dihyroxyvitamin D3 on skin

Abstract

Photoaging and carcinogenesis are facilitated by oxidative stress, inflammation, angiogenesis, and extracellular matrix (ECM) remodeling. Oxidative effects include DNA damage, membrane oxidation, lipid peroxidation, and alterations in the expression of p53 and antioxidant enzymes. The inflammatory and angiogenesis mediators include interleukin-1, tumor necrosis factor-α, interleukin-8, transforming growth factor-β, and vascular endothelial growth factor. ECM remodeling includes alterations in the expression and organization of collagen, elastin, matrix metalloproteinases, and elastase. 1α, 25-dihydroxy-vitamin D3 has antioxidant, anti-inflammatory, and ECM regulatory properties, and can counteract the processes that facilitate photoaging and carcinogenesis. This review provides an overview of the beneficial effects of vitamin D supplementation at a molecular level, followed by a brief discussion regarding its use as a supplement.
