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

MNADK, a novel liver-enriched mitochondrion-localized NAD kinase
Biology Open, 2013 Summary NADP+ and its reducing equivalent NADPH are essential for counteracting oxidative damage. Mitochondria are the major source of oxidative stress, since the majority of superoxide is generated from the mitochondrial respiratory chain. Because NADP+

The effector AvrRxo1 phosphorylates NAD in planta. [PDF]
PLoS 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 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

NAD Kinase in Higher Plants [PDF]
Plant Physiology, 1966 NAD kinase was exclusively found in the soluble portion of the cell components. The enzyme was purified about 100-fold from sucrose extracts of spinach leaves.Plant NAD kinase catalyzes formation of NADP from NAD, ATP, and Mg(++), but scarcely any formation of NADPH from NADH. NADH was a very potent competitive inhibitor of NAD phosphorylation by plant

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.

Frontiers 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

Journal of Ginseng Research, 2020 Background: The replicative senescence of human dermal fibroblasts (HDFs) is accompanied by growth arrest. In our previous study, the treatment of senescent HDFs with Rg3(S) lowered the intrinsic reactive oxygen species (ROS) levels and reversed cellular

Frontiers in Endocrinology, 2022 Cellular senescence is a stress or damage response by which a cell adopts of state of essentially permanent proliferative arrest, coupled to the secretion of a number of biologically active molecules. This senescence-associated secretory phenotype (SASP)

The NAD Kinases of Saccharomyces cerevisiae [PDF]
European 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
