Crossroads between peripheral atherosclerosis, western-type diet and skeletal muscle pathophysiology: emphasis on apolipoprotein E deficiency and peripheral arterial disease [PDF]

, 2017
Atherosclerosis is a chronic inflammatory process that, in the presence of hyperlipidaemia, promotes the formation of atheromatous plaques in large vessels of the cardiovascular system.

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Measuring CD38 Hydrolase and Cyclase Activities: 1,N6-Ethenonicotinamide Adenine Dinucleotide (ε-NAD) and Nicotinamide Guanine Dinucleotide (NGD) Fluorescence-based Methods

Bio-Protocol, 2018
CD38 is a multifunctional enzyme involved in calcium signaling and Nicotinamide Adenine Dinucleotide (NAD+) metabolism. Through its major activity, the hydrolysis of NAD+, CD38 helps maintain the appropriate levels of this molecule for all NAD+-dependent

NMNAT1 inhibits axon degeneration via blockade of SARM1-mediated NAD+ depletion [PDF]

, 2016
Overexpression of the NAD(+) biosynthetic enzyme NMNAT1 leads to preservation of injured axons. While increased NAD(+) or decreased NMN levels are thought to be critical to this process, the mechanism(s) of this axon protection remain obscure.

Anticancer sensitivities and biological characteristics of HCT116 cells resistant to the selective poly(ADP‐ribose) glycohydrolase inhibitor

FEBS Open Bio, EarlyView.
We analyzed alterations of PAR metabolism‐related proteins in PARG inhibitor‐resistant HCT116RPDD cells. Although PARG levels remained unchanged, HCT116RPDD cells exhibited reduced PARP1 and ARH3 expression and elevated PAR levels. Interestingly, HCT116RPDD cells exhibited slightly elevated intracellular NAD+/NADH and ATP levels. Our findings suggest a

New insights into the autophagy-NAD axis in brain disease

Cell Reports, 2023
Sun et al. demonstrate that defects in autophagy cause nicotinamide adenine dinucleotide (NAD) depletion and neurotoxicity.1 Restoring NAD levels rescues cytotoxicity in autophagy-deficient neurons, providing a potential therapy for neurodegenerative and

Studies with Analogues of Nicotinamide Adenine Dinucleotide [PDF]

European Journal of Biochemistry, 1974
Through a series of correlative studies, the stereochemistry of the enzymatic processes with the coenzyme analogues of NAD+, 3‐acetylpyridine‐adenine dinucleotide, thionicotinamide‐adenine dinucleotide and 3‐cyanopyridine‐adenine dinucleotide, have been examined for horse liver and yeast alcohol dehydrogenase (both A‐specific for NAD+) and glutamate ...

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

Aging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

The function of nicotinamide phosphoribosyl transferase (NAMPT) and its role in diseases

Frontiers in Molecular Biosciences
Nicotinamide phosphoribosyl transferase (NAMPT) is a rate-limiting enzyme in the mammalian nicotinamide adenine dinucleotide (NAD) salvage pathway, and plays a vital role in the regulation of cell metabolic activity, reprogramming, aging and apoptosis ...
