Nutraceutical activation of Sirt1: a review
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]
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

From meadows to milk to mucosa – adaptation of Streptococcus and Lactococcus species to their nutritional environments [PDF]
Lactic acid bacteria (LAB) are indigenous to food-related habitats as well as associated with the mucosal surfaces of animals. The LAB family Streptococcaceae consists of the genera Lactococcus and Streptococcus.

Endogenous nicotinamide riboside metabolism protects against diet-induced liver damage
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.

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

Genome-wide analysis of the UDP-glucose dehydrogenase gene family in Arabidopsis, a key enzyme for matrix polysaccharides in cell walls [PDF]
Arabidopsis cell walls contain large amounts of pectins and hemicelluloses, which are predominantly synthesized via the common precursor UDP-glucuronic acid.

Background: The replicative senescence of human dermal fibroblasts (HDFs) is accompanied by growth arrest. In our previous study, the treatment of senescent HDFs with Rg3(S) lowered the intrinsic reactive oxygen species (ROS) levels and reversed cellular
