miR-146a impedes the anti-aging effect of AMPK via NAMPT suppression and NAD+/SIRT inactivation
Signal Transduction and Targeted Therapy, 2022 Nicotinamide adenine dinucleotide (NAD+) is indispensable for the anti-aging activity of the sirtuin (SIRT) family enzymes. AMP-activated protein kinase (AMPK) upregulates NAD+ synthesis and SIRT activity in a nicotinamide phosphoribosyltransferase ...

Astrocytes and Microglia Are Resistant to NAD+-Mediated Cell Death Along the ARTC2/P2X7 Axis
Frontiers in Molecular Neuroscience, 2020 ADP-ribosylation of the P2X7k splice variant on mouse T cells by Ecto-ADP-ribosyltransferase ARTC2.2 in response to its substrate extracellular nicotinamide adenine dinucleotide (NAD+) triggers cell death. Since NAD+ is released as a danger signal during

Flavopiridol Protects Against Inflammation by Attenuating Leukocyte-Endothelial Interaction via Inhibition of Cyclin-Dependent Kinase 9 [PDF]
, 2011 Objective: The cyclin-dependent kinase (CDK) inhibitor flavopiridol is currently being tested in clinical trials as anticancer drug. Beyond its cell death–inducing action, we hypothesized that flavopiridol affects inflammatory processes.

NAD Kinases Use Substrate-assisted Catalysis for Specific Recognition of NAD [PDF]
Journal of Biological Chemistry, 2007 Here we describe the crystal structures of the NAD kinase (LmNADK1) from Listeria monocytogenes in complex with its substrate NAD, its product NADP, or two synthesized NAD mimics. We identified one of the NAD mimics, di-adenosine diphosphate, as a new substrate for LmNADK1, whereas we showed that the closely related compound di-5'-thioadenosine is a ...

Functions and Regulation of eukaryotic NAD kinase - an essential enzyme for NADP biosynthesis [PDF]
, 2008 NAD and NADP, both major carriers of cellular reducing equivalents, are of vital importance in diverse metabolic and signaling processes. Efficient maintenance and regulation of the reduction-oxidation status is therefore crucial within the cell.

Calmodulin Is the Fundamental Regulator of NADK-Mediated NAD Signaling in Plants
Frontiers in Plant Science, 2019 Calcium (Ca2+) signaling and nicotinamide adenine dinucleotide (NAD) signaling are two basic signal regulation pathways in organisms, playing crucial roles in signal transduction, energy metabolism, stress tolerance, and various developmental processes ...

Sensitive superoxide detection in vascular cells by the new chemiluminescence dye L-012 [PDF]
, 1999 The detection superoxide production in vascular cells is usually limited by a low sensitivity of available assays, We tested the applicability of the luminol derivate L-012 {[}8-amino-5-chloro-7-phenylpyridol{[}3,4-d]pyridazine-l,4(2H,3H)dione] to ...
