16 SIRT1 is broadly expressed in metabolically active tissues 17 and regulates lipid metabolism, 18 mitochondrial maintenance, ROS clearance, autophagy, and immune balance by deacetylating key transcriptional regulators, including peroxisome proliferator-activated receptor gamma coactivator 1- (PGC-1), Forkhead Box O (FOXO), and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-B) and p53
V itamin B12 , also known as cobalamin, is a water-soluble vitamin that is essential for several critical physiological processes
