Together, it can be concluded that intracellular selenium status (hydrogen selenide) regulates the expressions of seleno-GPxs primarily at the translation level by controlling the stability of their mRNAs as well as by facilitating the biosynthesis and subsequent incorporation of Sec into the peptide sequence (Fig
Vitamin C, when applied to the skin, serves as an antioxidant, leading to protection from oxidative stressors from the environment [like free radicals]. Its also necessary for creating healthy collagen fibers and protects against collagen degradation, adds Magovern
Vitamin D is a neurosteroid that is active in brain development
Summer can increase irritation risk because people layer sunscreen, cosmetics, after-sun gels, fragrances, and active skincare while the skin is exposed to heat, sweat, and ultraviolet radiation
The peptide upregulates MMP-2 expression in dermal fibroblasts by 85%, facilitating breakdown of damaged collagen and enabling cellular migration through dense matrix environments, while simultaneously enhancing production of tissue inhibitors of metalloproteinases (TIMPs) to prevent excessive degradation
