Adenine nucleotides and ventricular fibrillation
Journal of Molecular and Cellular Cardiology, 1987The isolated perfused rat heart was used to study the influence of adenine nucleotides and their metabolites on vulnerability to ventricular fibrillation. In this model the incidence of ventricular arrhythmias after coronary artery ligation is determined by the extracellular K+ concentration; with perfusate K+ of 2.0 and 3.0 mmol/l hearts develop a ...

Biochimica et Biophysica Acta, 1953
Abstract A new nucleotide has been shown to be present in commercial samples of adenosine-5′-triphosphate (ATP). The analytical data suggest the structure adenosine-5′-tetraphosphate.

Measurement of adenine nucleotides in plasma
Luminescence, 2003AbstractThe goal of this study was to identify the most important variables affecting bioluminescent ATP, ADP and AMP measurements in plasma and to develop an assay that takes these variables into account. Blood samples were drawn from conscious dogs.

Adenine Nucleotide Translocator in Heart
Molecular Genetics and Metabolism, 2000The adenine nucleotide translocator (ANT) spans the inner mitochondrial membrane and facilitates exchange of cytosolic ADP for ATP within the mitochondrial matrix. ANT represents the most prominent single protein component of the inner mitochondrial membrane (1).

Adenine nucleotide transport during cardiac ischemia
American Journal of Physiology-Heart and Circulatory Physiology, 1981The suggestion that long-chain acyl coenzyme A (CoA) derivatives may inhibit mitochondrial adenine nucleotide transport in heart cells during ischemia has been reevaluated. The effectiveness of media palmitoyl-CoA as an inhibitor is a function of mitochondrial protein and media adenine nucleotide concentrations.

The adenine nucleotide translocator in apoptosis
Biochimie, 2002Alteration of mitochondrial membrane permeability is a central mechanism leading invariably to cell death, which results, at least in part, from the opening of the permeability transition pore complex (PTPC). Indeed, extended PTPC opening is sufficient to trigger an increase in mitochondrial membrane permeability and apoptosis.

Adenine Nucleotide Degradation in Striated Muscle
International Journal of Sports Medicine, 1990Adenine nucleotides play a central role in cellular processes involving the transduction of energy. Among striated muscles, the management of adenine nucleotide catabolism differs greatly. These differences can be understood by considering the distribution, activity, and kinetic characteristics of degradative enzymes.

K channel interaction with adenine nucleotides
Journal of Molecular and Cellular Cardiology, 2005ATP-sensitive potassium (K(ATP)) channels are regulated by adenine nucleotides to convert changes in cellular metabolic levels into membrane excitability. Hence, elucidation of interaction of SUR and Kir6.x with adenine nucleotides is an important issue to understand the molecular mechanisms underlying the metabolic regulation of the K(ATP) channels ...

Adenine nucleotide translocation in cauliflower mitochondria
Archives of Biochemistry and Biophysics, 1976Abstract The exchange of adenine nucleotides in cauliflower mitochondria was studied. Although these mitochondria translocate ADP and ATP at high rates and possess high affinity binding for the nucleotides, they differ from mammalian mitochondria with respect to the action of atractyloside. It was observed that (i) atractyloside at a concentration of
