It is FDA-approved for clinical use and stimulates endogenous GH secretion

Future work may adapt this strategy into mRNA-based therapeutics or pegylated protein formulations with improved stability and targeted delivery

Taken together, these findings suggest that upon DNA damage, substrate selectivity may be regulated by PTMs that alter binding ability of SIRT1 to specific substrates, rather than the enzymatic activity of SIRT1, which makes possible substrate selectivity in which the p53 deacetylation is suppressed while the MDM2 deacetylation is maintained

UV exposure, pollution, stress, and even the normal act of breathing create these unstable molecules

Thus, the imbalances in antioxidant defense enzymes, particularly SOD and GSH-Px activities, were identified in HD, confirming the presence of oxidative stress
