Nutraceutical activation of Sirt1: a review
Open Heart, 2022 The deacetylase sirtuin 1 (Sirt1), activated by calorie restriction and fasting, exerts several complementary effects on cellular function that are favourable to healthspan; it is often thought of as an ‘anti-aging’ enzyme. Practical measures which might

NAD Kinase in Higher Plants [PDF]
Plant Physiology, 1966 NAD kinase was exclusively found in the soluble portion of the cell components. The enzyme was purified about 100-fold from sucrose extracts of spinach leaves.Plant NAD kinase catalyzes formation of NADP from NAD, ATP, and Mg(++), but scarcely any formation of NADPH from NADH. NADH was a very potent competitive inhibitor of NAD phosphorylation by plant

Endogenous nicotinamide riboside metabolism protects against diet-induced liver damage
Nature Communications, 2019 Nicotinamide adenine dinucleotide (NAD+) sustains cellular energy metabolism, functions as a substrate of Sirt and PARP enzymes, and its supplementation is explored therapeutically in aging and other contexts.

Frontiers in Immunology, 2019 The G protein-coupled P2Y11 receptor is known to sense extracellular ATP during inflammatory and immune responses. The dinucleotide NAD+ has also been proposed to be a P2Y11 receptor ligand but its role is less clear. Here, we have examined for the first
