NAD+

NAD(+) metabolism and its roles in cellular processes during ageing.

Nicotinamide adenine dinucleotide (NAD) is a coenzyme for redox reactions, making it central to energy metabolism. NAD is also an essential cofactor for non-redox NAD-dependent enzymes, including sirtuins, CD38 and poly(ADP-ribose) polymerases. NAD can directly...

NAD(+) Metabolism in Cardiac Health, Aging, and Disease.

Nicotinamide adenine dinucleotide (NAD) is a central metabolite involved in energy and redox homeostasis as well as in DNA repair and protein deacetylation reactions. Pharmacological or genetic inhibition of NAD-degrading enzymes, external supplementation of NAD...

NAD(+) metabolism, stemness, the immune response, and cancer.

NAD was discovered during yeast fermentation, and since its discovery, its important roles in redox metabolism, aging, and longevity, the immune system and DNA repair have been highlighted. A deregulation of the NAD levels has...

Roles of NAD(+) in Health and Aging.

NAD, the essential metabolite involved in multiple reactions such as the regulation of cellular metabolism, energy production, DNA repair, mitophagy and autophagy, inflammation, and neuronal function, has been the subject of intense research in the...

NAD(+) supplementation reduces neuroinflammation and cell senescence in a transgenic mouse model of Alzheimer's disease via cGAS-STING.

Alzheimer's disease (AD) is a progressive and fatal neurodegenerative disorder. Impaired neuronal bioenergetics and neuroinflammation are thought to play key roles in the progression of AD, but their interplay is not clear. Nicotinamide adenine dinucleotide...

SIRT6 in Aging, Metabolism, Inflammation and Cardiovascular Diseases.

As an important NAD-dependent enzyme, SIRT6 has received significant attention since its discovery. In view of observations that SIRT6-deficient animals exhibit genomic instability and metabolic disorders and undergo early death, SIRT6 has long been considered...

Signaling pathways and effectors of aging.

Aging leads to and is associated with aberrant function of multiple signaling pathways and a host of factors that maintain cellular health. Under normal conditions, the prolongevity, 5' AMP-activated protein kinase (AMPK), is dedicated to...

Role of NAD(+) in regulating cellular and metabolic signaling pathways.

Nicotinamide adenine dinucleotide (NAD), a critical coenzyme present in every living cell, is involved in a myriad of metabolic processes associated with cellular bioenergetics. For this reason, NAD is often studied in the context of...
