4-Pyridone-3-carboxamide-1-β-d-ribonucleoside Triphosphate (4PyTP), a Novel NAD+ Metabolite Accumulating in Erythrocytes of Uremic Children: A Biomarker for a Toxic NAD+ Analogue in Other Tissues?

Toxins, 2011
We have identified a novel nucleotide, 4-pyridone 3/5-carboxamide ribonucleoside triphosphate (4PyTP), which accumulates in human erythrocytes during renal failure.

Nicotinamide adenine dinucleotide is transported into mammalian mitochondria

eLife, 2018
Mitochondrial NAD levels influence fuel selection, circadian rhythms, and cell survival under stress. It has alternately been argued that NAD in mammalian mitochondria arises from import of cytosolic nicotinamide (NAM), nicotinamide mononucleotide (NMN),

Nicotinamide Riboside, an NAD precursor and supplement, reduces liver damage caused by sepsis

Revista Científica
Sepsis leads to liver failure and eventually death. The supplement nicotinamide riboside is an antioxidant and nicotinamide adenine dinucleotide precursor.

Complementary NAD+ replacement strategies fail to functionally protect dystrophin-deficient muscle

Skeletal Muscle, 2020
Background Duchenne muscular dystrophy (DMD) is a progressive muscle wasting disorder stemming from a loss of functional dystrophin. Current therapeutic options for DMD are limited, as small molecule modalities remain largely unable to decrease the ...

Nicotinamide riboside attenuates age-associated metabolic and functional changes in hematopoietic stem cells

Nature Communications, 2021
Aged hematopoietic stem cells (HSC) are characterised by reduced regenerative potential and a loss of quiescence. Here, the authors show nicotinamide riboside treatment shrinks the age-enlarged stem cell pool and shifts aged HSC functionally ...

NRK1 controls nicotinamide mononucleotide and nicotinamide riboside metabolism in mammalian cells

Nature Communications, 2016
Raising cellular levels of the metabolic cofactor NAD+ reverses key indicators of aging. Here, Ratajczak et al. show that cellular levels of NAD+ depend on the extracellular catalytic activity of NRK1, which processes two NAD+precursors, nicotinamide ...

Niacin restriction with NAMPT-inhibition is synthetic lethal to neuroendocrine carcinoma

Nature Communications, 2023
Nicotinamide phosphoribosyltransferase (NAMPT) plays a major role in NAD biosynthesis in many cancers and is an attractive potential cancer target. However, factors dictating therapeutic efficacy of NAMPT inhibitors (NAMPTi) are unclear.

Nicotinamide riboside kinases regulate skeletal muscle fiber-type specification and are rate-limiting for metabolic adaptations during regeneration

Frontiers in Cell and Developmental Biology, 2022
Nicotinamide riboside kinases (NRKs) control the conversion of dietary Nicotinamide Riboside (NR) to NAD+, but little is known about their contribution to endogenous NAD+ turnover and muscle plasticity during skeletal muscle growth and remodeling.

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.
