Metabolic Aspects of Adenosine Functions in the Brain.

Frontiers in pharmacology

Garcia-Gil M, Camici M, Allegrini S, Pesi R, Tozzi MG.
PMID: 34054547
Front Pharmacol. 2021 May 14;12:672182. doi: 10.3389/fphar.2021.672182. eCollection 2021.

Adenosine, acting both through G-protein coupled adenosine receptors and intracellularly, plays a complex role in multiple physiological and pathophysiological processes by modulating neuronal plasticity, astrocytic activity, learning and memory, motor function, feeding, control of sleep and aging. Adenosine is...

Adenosine Kinase Expression Determines DNA Methylation in Cancer Cell Lines.

ACS pharmacology & translational science

Wahba AE, Fedele D, Gebril H, AlHarfoush E, Toti KS, Jacobson KA, Boison D.
PMID: 33860193
ACS Pharmacol Transl Sci. 2021 Feb 16;4(2):680-686. doi: 10.1021/acsptsci.1c00008. eCollection 2021 Apr 09.

DNA methylation has a major role in cancer, and its inhibitors are used therapeutically. DNA methylation depends on methyl group flux through the transmethylation pathway, which forms adenosine. We hypothesized that an adenosine kinase isoform with nuclear expression (ADK-L)...

Adenosine kinase inhibition promotes proliferation of neural stem cells after traumatic brain injury.

PMID: 32322821
Brain Commun. 2020;2(1):fcaa017. doi: 10.1093/braincomms/fcaa017. Epub 2020 Feb 20.

Traumatic brain injury (TBI) is a major public health concern and remains a leading cause of disability and socio-economic burden. To date, there is no proven therapy that promotes brain repair following an injury to the brain. In this...

Clinical utility of methionine restriction in adenosine kinase deficiency.

JIMD reports

Almuhsen N, Guay SP, Lefrancois M, Gauvin C, Al Bahlani AQ, Ahmed N, Saint-Martin C, Gagnon T, Waters P, Braverman N, Buhas D.
PMID: 34485018
JIMD Rep. 2021 Jul 27;61(1):52-59. doi: 10.1002/jmd2.12238. eCollection 2021 Sep.

Adenosine kinase (ADK) deficiency is a rare autosomal recessive inborn error of metabolism involving the methionine and purine metabolic pathways. Prior reports show that most patients present in infancy with jaundice, hypotonia, developmental delay, and mild dysmorphic features. Characteristic...

Clearance of rapid adenosine release is regulated by nucleoside transporters and metabolism.

Pharmacology research & perspectives

Nguyen MD, Ross AE, Ryals M, Lee ST, Venton BJ.
PMID: 27022463
Pharmacol Res Perspect. 2015 Nov 16;3(6):e00189. doi: 10.1002/prp2.189. eCollection 2015 Dec.

Adenosine is a neuromodulator that regulates neurotransmission in the brain and central nervous system. Recently, spontaneous adenosine release that is cleared in 3-4 sec was discovered in mouse spinal cord slices and anesthetized rat brains. Here, we examined the...

Corrigendum: Adenosine Kinase Inhibition Protects against Cranial Radiation-Induced Cognitive Dysfunction.

Frontiers in molecular neuroscience

Acharya MM, Baulch JE, Lusardi TA, Allen BD, Chmielewski NN, Baddour AAD, Limoli CL, Boison D.
PMID: 28698714
Front Mol Neurosci. 2017 Jul 10;10:218. doi: 10.3389/fnmol.2017.00218. eCollection 2017.

[This corrects the article on p. 42 in vol. 9, PMID: 27375429.].

Adenosine kinase is a new therapeutic target to prevent ischemic neuronal death.

The open drug discovery journal

Boison D, Shen HY.
PMID: 24089624
Open Drug Discov J. 2010 Jan 01;2(3):108-118.

The brain has evolved several endogenous mechanisms to protect itself from the deleterious consequences of stroke. One of those endogenous neuroprotective systems is centered on the purine ribonucleoside adenosine, which exerts potent neuroprotective functions within the brain. One major...

Phosphorylation of cytokinin by adenosine kinase from wheat germ.

Plant physiology

Chen CM, Eckert RL.
PMID: 16659870
Plant Physiol. 1977 Mar;59(3):443-7. doi: 10.1104/pp.59.3.443.

Adenosine kinase was partially purified from wheat germ. This enzyme preparation, which was devoid of adenine phosphoribosyltransferase and nearly free of adenosine deaminase but contained adenylate kinase, rapidly phosphorylated adenosine and a cytokinin, N(6)-(delta(2)-isopentenyl)adenosine. Electrophoretic analysis indicated that only...

Adenosine dysfunction in astrogliosis: cause for seizure generation?.

Neuron glia biology

Li T, Quan Lan J, Fredholm BB, Simon RP, Boison D.
PMID: 18634566
Neuron Glia Biol. 2007 Nov;3(4):353-66. doi: 10.1017/S1740925X0800015X.

Epilepsy is characterized by both neuronal and astroglial dysfunction. The endogenous anticonvulsant adenosine, the level of which is largely controlled by astrocytes, might provide a crucial link between astrocyte and neuron dysfunction in epilepsy. Here we have studied astrogliosis,...

Adenosine neuromodulation and traumatic brain injury.

Current neuropharmacology

Lusardi TA.
PMID: 20190964
Curr Neuropharmacol. 2009 Sep;7(3):228-37. doi: 10.2174/157015909789152137.

Adenosine is a ubiquitous signaling molecule, with widespread activity across all organ systems. There is evidence that adenosine regulation is a significant factor in traumatic brain injury (TBI) onset, recovery, and outcome, and a growing body of experimental work...

Nucleotide-metabolism and chromosome alterations in human-malignant melanoma xenografts.

International journal of oncology

Bardot V, Luccioni C, Dutrillaux A, Blancho D, Beaumatin J, Dutrillaux B.
PMID: 21552873
Int J Oncol. 1995 Sep;7(3):547-54.

The karyotypes of human melanomas exhibit multiple chromosome alterations. Recurrent deletions of 9p, 10q and 14q arms, which carry genes encoding for enzymes of purine metabolism, were also found in human gliomas, another neuroectodermal tumor previously studied for both...

Preventing ATP Degradation by ASO-Mediated Knockdown of CD39 and CD73 Results in A2aR-Independent Rescue of T Cell Proliferation.

Molecular therapy. Nucleic acids

Festag J, Thelemann T, Schell M, Raith S, Michel S, Jaschinski F, Klar R.

The adenosine axis contributes to the suppression of antitumor immune responses. The ectonucleotidase CD39 degrades extracellular adenosine triphosphate (ATP) to adenosine monophosphate (AMP), which is degraded to adenosine by CD73. Adenosine binds to, e.g., the A2a receptor (A2aR), which...
