Extracellular Degradation Into Adenosine and the Activities of Adenosine Kinase and AMPK Mediate Extracellular NAD+-Produced Increases in the Adenylate Pool of BV2 Microglia Under Basal Conditions

open access: yesFrontiers in Cellular Neuroscience, 2018
Cumulating evidence has indicated NAD+ deficiency as a common central pathological factor of multiple diseases and aging. NAD+ supplement is highly protective in various disease and aging models, while two key questions have remained unanswered: (1) Does

Activation of Akt by advanced glycation end products (AGEs): involvement of IGF-1 receptor and caveolin-1. [PDF]

open access: yesPLoS ONE, 2013
Diabetes is characterized by chronic hyperglycemia, which in turn facilitates the formation of advanced glycation end products (AGEs). AGEs activate signaling proteins such as Src, Akt and ERK1/2.

Impaired nicotinamide adenine dinucleotide (NAD+) metabolism in diabetes and diabetic tissues: Implications for nicotinamide‐related compound treatment

open access: yesJournal of Diabetes Investigation, 2020
One of the biochemical abnormalities found in diabetic tissues is a decrease in the cytosolic oxidized to reduced forms of the nicotinamide adenine dinucleotide ratio (NAD+/NADH also known as pseudohypoxia) caused by oxidation of excessive substrates ...

The NAD Kinases of Saccharomyces cerevisiae [PDF]

open access: yesEuropean Journal of Biochemistry, 1970
Subcellular fractions of a strain of Saccharomyces cerevisiae have been prepared by enzymic digestion of the cell walls, osmotic lysis of the protoplasts and sorbitol density gradient centrifugation of the lysate. The mitochondrial fraction has both NAD‐ and NADH‐phosphorylating enzymes, whilst the cytoplasm contains a single NAD‐specific kinase. These

Combinatorial strategy using protein kinase inhibitors and a cytotoxic compound for highly resistant glioblastoma cells : "in vitro studies" [PDF]

open access: yes, 2007
Glioblastoma multiforme (GBM) is the most frequent and the most aggesssive malignant neoplasm of the human central nervous system (CNS), with a median survival of less than one year. These neoplasms are radio- and chemo-resistant, and are highly invasive,

The effector AvrRxo1 phosphorylates NAD in planta. [PDF]

open access: yesPLoS Pathogens, 2017
Gram-negative bacterial pathogens of plants and animals employ type III secreted effectors to suppress innate immunity. Most characterized effectors work through modification of host proteins or transcriptional regulators, although a few are known to ...

Nutraceutical activation of Sirt1: a review

open access: yesOpen Heart, 2022
The deacetylase sirtuin 1 (Sirt1), activated by calorie restriction and fasting, exerts several complementary effects on cellular function that are favourable to healthspan; it is often thought of as an ‘anti-aging’ enzyme. Practical measures which might

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

open access: yesFEBS 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

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.

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

open access: yesFrontiers 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
