Inhibition of pigeon liver NAD kinase by a non‐phosphorylatible analogue of NAD [PDF]

FEBS Letters, 1971
Nicotinamide-2’-deoxy-adenosine dinucleotide tNdAD) has previously been prepared enzymatically [ 11 and chemically [2] , and its interactions with dehydrogenases were studied. Since this analogue of NAD differs from the natural coenzyme in lacking the 2’-hydroxyl on the adenosine ribose, it cannot be phosphorylated by NAD kinase (ATP:NAD 2 ...

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.

The Human G Protein-Coupled ATP Receptor P2Y11 Is Associated With IL-10 Driven Macrophage Differentiation

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

Stereoisomer-specific ginsenoside 20(S)-Rg3 reverses replicative senescence of human diploid fibroblasts via Akt-mTOR-Sirtuin signaling

Journal of Ginseng Research, 2020
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

Extracellular Nicotinamide Phosphoribosyltransferase Is a Component of the Senescence-Associated Secretory Phenotype

Frontiers in Endocrinology, 2022
Cellular senescence is a stress or damage response by which a cell adopts of state of essentially permanent proliferative arrest, coupled to the secretion of a number of biologically active molecules. This senescence-associated secretory phenotype (SASP)

Cisplatin-Induced Kidney Toxicity: Potential Roles of Major NAD⁺-Dependent Enzymes and Plant-Derived Natural Products

Biomolecules, 2022
Cisplatin is an FDA approved anti-cancer drug that is widely used for the treatment of a variety of solid tumors. However, the severe adverse effects of cisplatin, particularly kidney toxicity, restrict its clinical and medication applications. The major

Nicotinamide riboside kinases display redundancy in mediating nicotinamide mononucleotide and nicotinamide riboside metabolism in skeletal muscle cells

Molecular Metabolism, 2017
Objective: Augmenting nicotinamide adenine dinucleotide (NAD+) availability may protect skeletal muscle from age-related metabolic decline. Dietary supplementation of NAD+ precursors nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR) appear

NAD Kinase by Quinolinic Acid

, 2003
NADP is essential for biosynthetic pathways, energy, and signal transduction. In living organisms, NADP biosynthesis proceeds through the phosphorylation of NAD with a reaction catalyzed by NAD kinase.

Fluorometric procedures for measuring triglyceride concentrations in small amounts of tissue and plasma.

Journal of Lipid Research, 1988
It has been previously shown that triglycerides can be specifically hydrolyzed by lipase from Rhizopus arrhizus in the presence of hog liver esterase and sodium dodecyl sulfate.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.
