Hidden Pool of Cardiac Adenine Nucleotides That Controls Adenosine Production

Pharmaceuticals, 2023
Myocardial ischemic adenosine production decreases in subsequent events that may blunt its protective functions. To test the relation between total or mitochondrial cardiac adenine nucleotide pool (TAN) on the energy status with adenosine production ...

CoCl₂-Mimicked Endothelial Cell Hypoxia Induces Nucleotide Depletion and Functional Impairment That Is Reversed by Nucleotide Precursors

Biomedicines, 2022
Chronic hypoxia drives vascular dysfunction by various mechanisms, including changes in mitochondrial respiration. Although endothelial cells (ECs) rely predominantly on glycolysis, hypoxia is known to alter oxidative phosphorylation, promote oxidative ...

A liquid chromatography-tandem mass spectrometry based method for the quantification of adenosine nucleotides and NAD precursors and products in various biological samples

Frontiers in Immunology, 2023
Adenine nucleotides (AN) are ubiquitous metabolites that regulate cellular energy metabolism and modulate cell communication and inflammation. To understand how disturbances in AN balance arise and affect cellular function, robust quantification ...

Insight into an Oxidative DNA-Cleaving DNAzyme: Multiple Cofactors, the Catalytic Core Map and a Highly Efficient Variant

iScience, 2020
Summary: An oxidative DNA-cleaving DNAzyme (PL) employs a double-cofactor model “X/Cu2+” for catalysis. Herein, we verified that reduced nicotinamide adenine dinucleotide (NADH), flavin mononucleotide, cysteine, dithiothreitol, catechol, resorcinol ...

Substrate binding in the mitochondrial ADP/ATP carrier is a step-wise process guiding the structural changes in the transport cycle

Nature Communications, 2022
The mitochondrial ADP/ATP carrier transports adenine nucleotides. Here, authors identify the residues involved in substrate binding. One set forms the central substrate binding site and two asparagine/arginine pairs help to guide the substrates during ...

Adenine Nucleotide and Nicotinamide Adenine Dinucleotide Measurements in Plants [PDF]

Current Protocols in Plant Biology, 2020
AbstractAs the principal co‐factors of many metabolic pathways, the measurement of both adenine nucleotides and nicotinamide adenine dinucleotide provides important information about cellular energy metabolism. However, given their rapid and reversible conversion as well as their relatively low concentration ranges, it is difficult to measure these ...

The evolution of purinergic receptors involved in recognition of a blood meal by hematophagous insects

Memorias do Instituto Oswaldo Cruz, 1987
Many blood feeders use adenine nucleotides as cues for locating blood meal. Structure-activity relationship of adenine nucleotides as phagostimulants varies between closely-related species of blood feeders. It is suggested that a preexisting diverse pool

Development and application of LC/HRPS for quantification of adenine nucleotides, creatine phosphate, and creatine in sturgeon spermatozoa

Czech Journal of Animal Science, 2017
The objective of this study was to investigate the applicability of liquid chromatography coupled with high resolution product scan (LC/HRPS) mass spectrometry for simultaneous quantification of adenine nucleotides, creatine phosphate, and creatine ...

An Intermediary Role of Adenine Nucleotides on Free Fatty Acids-Induced Hyperglycemia in Obese Mice

Frontiers in Endocrinology, 2019
Increased plasma free fatty acids (FFA) level plays a central role in the development of type 2 diabetes. Our previous studies have shown that plasma 5′-adenosine monophosphate (5′-AMP) elevates and acts as a potential upstream regulator of hyperglycemia
