Presynaptic Purinergic Modulation of the Rat Neuro-Muscular Transmission

open access: yesCurrent Issues in Molecular Biology, 2023
ATP, being a well-known universal high-energy compound, plays an important role as a signaling molecule and together with its metabolite adenosine they both attenuate the release of acetylcholine in the neuro-muscular synapse acting through membrane P2 ...

Adenosine deaminase and adenosine kinase in rat hepatomas and kidney tumours [PDF]

open access: yesBritish Journal of Cancer, 1978
Adenosine deaminase and adenosine kinase have been measured in rat liver, 12 transplantable hepatomas, regenerating, foetal and neonatal liver, adult and neonatal rat kidney and 2 transplantable kidney tumours. Adenosine, deaminase activity, relative to the normal liver value, was elevated 2-4 fold in hepatomas of rapid growth rate, was in the normal ...

Interaction of renin–angiotensin system and adenosine monophosphate–activated protein kinase signaling pathway in renal carcinogenesis of uninephrectomized rats

open access: yesTumor Biology, 2017
Renin–angiotensin system and adenosine monophosphate–activated protein kinase signaling pathway both play important roles in carcinogenesis, but the interplay of renin–angiotensin system and adenosine monophosphate–activated protein kinase in ...

Working memory and the homeostatic control of brain adenosine by adenosine kinase [PDF]

open access: yesNeuroscience, 2012
The neuromodulator adenosine maintains brain homeostasis and regulates complex behaviour via activation of inhibitory and excitatory adenosine receptors (ARs) in a brain region-specific manner. AR antagonists such as caffeine have been shown to ameliorate cognitive impairments in animal disease models but their effects on learning and memory in normal ...

Adenosine Kinase Deficiency: Report and Review [PDF]

open access: yesNeuropediatrics, 2018
AbstractAdenosine kinase (ADK) deficiency (OMIM [online mendelian inheritance in man]: 614300) is an autosomal recessive disorder of adenosine and methionine metabolism, with a unique clinical phenotype, mainly involving the central nervous system and dysmorphic features.

The dipeptidyl peptidase-IV inhibitor gemigliptin alone or in combination with NVP-AUY922 has a cytotoxic activity in thyroid carcinoma cells

open access: yesTumor Biology, 2017
The effect of the dipeptidyl peptidase-IV inhibitor gemigliptin alone or in combination with the heat shock protein 90 inhibitor NVP-AUY922 (AUY922) on survival of thyroid carcinoma cells was elucidated. The SW1736 and TPC-1 human thyroid carcinoma cells

The adenosine kinase hypothesis of epileptogenesis [PDF]

open access: yesProgress in Neurobiology, 2008
Current therapies for epilepsy are largely symptomatic and do not affect the underlying mechanisms of disease progression, i.e. epileptogenesis. Given the large percentage of pharmacoresistant chronic epilepsies, novel approaches are needed to understand and modify the underlying pathogenetic mechanisms.

Properties of rat heart adenosine kinase [PDF]

open access: yesBiochemical Journal, 1984
Adenosine kinase was purified 870-fold from rat heart by a combination of gel filtration and affinity chromatography. The preparation was free of purine-metabolizing enzymes that could interfere in the assay of the kinase. A study of the properties of the purified enzyme showed that it is activated by Na+ and K+, it possesses a broad pH optimum between

Nucleoside Transport Inhibition by Dipyridamole Prevents Angiogenesis Impairment by Homocysteine and Adenosine

open access: yesJournal of Pharmacy & Pharmaceutical Sciences, 2015
Purpose: Adenosine plays an important role in the pathogenesis of homocysteine-associated vascular complications. Methods: This study examined the effects of dipyridamole, an inhibitor for nucleoside transport, on impaired angiogenic processes caused by ...

In vitro biosynthesis of ATP from adenosine and polyphosphate

open access: yesBioresources and Bioprocessing, 2021
Adenosine triphosphate (ATP) acts as a crucial energy currency in vivo, and it is a widely used energy and/or phosphate donor for enzyme-catalyzed reactions in vitro.
