Endogenous nicotinamide riboside metabolism protects against diet-induced liver damage

open access: yesNature 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.

Age- and AD-related redox state of NADH in subcellular compartments by fluorescence lifetime imaging microscopy. [PDF]

open access: yes, 2019
Nicotinamide adenine dinucleotide (reduced form: NADH) serves as a vital redox-energy currency for reduction-oxidation homeostasis and fulfilling energetic demands.

Can adenine nucleotides predict primary nonfunction of the human liver homograft? [PDF]

open access: yes, 1994
Sixty-eight primary liver grafts were analyzed to see whether adenine nucleotides (AN: ATP, ADP, and AMP) or purine catabolites (PC: adenosine, inosine, hypoxanthine, and xanthine) of tissue or effluent can predict primary graft nonfunction.

Pellagra: 4 D’s and 8 Points

open access: yesAdvances in Clinical Neuroscience & Rehabilitation, 2020
Pellagra has largely been forgotten. This is unfortunate as important lessons are to be learnt for the diseases and social consequences of poverty (and of affluence) that often involve dietary nicotinamide and nicotinamide adenine dinucleotide (NAD ...

The human silent information regulator (Sir)2 homologue hSIRT3 is a mitochondrial nicotinamide adenine dinucleotide-dependent deacetylase. [PDF]

open access: yes, 2002
The yeast silent information regulator (Sir)2 protein links cellular metabolism and transcriptional silencing through its nicotinamide adenine dinucleotide (NAD)-dependent histone deacetylase activity.

Binding of nicotinamide–adenine dinucleotides to diphtheria toxin [PDF]

open access: yesBiochemical Journal, 1967
1. Changes in protein fluorescence have been utilized in determining the stoicheiometry and dissociation constants of the complexes of diphtheria toxin with NADH2, NAD, NADPH2 and NADP. 2. The binding stoicheiometry is 2moles of NADH2 and 1mole of NADPH2/mole of diphtheria toxin. The binding sites for NADH2 appear to be equivalent and independent.

Nucleotides: Structure and Properties [PDF]

open access: yes, 2005
Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...

A Prebiotic Pathway to Nicotinamide Adenine Dinucleotide

open access: yesChemistry – A European Journal
AbstractEnzymes play a fundamental role in cellular metabolism. A wide range of enzymes require the presence of complementary coenzymes and cofactors to function properly. While coenzymes are believed to have been part of the last universal ancestor (LUCA) or have been present even earlier, the syntheses of crucial coenzymes like the redox‐active ...

NAD+ metabolism controls inflammation during senescence

open access: yesMolecular & Cellular Oncology, 2019
We have recently discovered that nicotinamide adenine dinucleotide metabolism controls the pro-inflammatory senescence-associated secretory phenotype during cellular senescence.
