An unexpected response to adenosine [PDF]

open access: yesNetherlands Heart Journal, 2014
Rhythm puzzle—answer The ECG shown in Fig. 1 is a narrow complex tachycardia with a frequency of 270 beats/min. Contradictory to expectations, the administration of adenosine resulted not in conversion of the arrhythmia, but in this accelerated rhythm, making an AV(N)RT unlikely.

Elucidating prognostic significance of purine metabolism in colorectal cancer through integrating data from transcriptomic, immunohistochemical, and single‐cell RNA sequencing analysis

open access: yesMolecular Oncology, EarlyView.
Low expression of five purine metabolism‐related genes (ADSL, APRT, ADCY3, NME3, NME6) was correlated with poor survival in colorectal cancer. Immunohistochemistry analysis showed that low NME3 (early stage) and low ADSL/NME6 (late stage) levels were associated with high risk.

Inadequate response to adenosine infusion during cardiac stress magnetic resonance imaging

open access: yesAnnals of Cardiac Anaesthesia, 2022
Aim: To determine the factors associated with an inadequate response to adenosine infusion during cardiac stress magnetic resonance imaging (MRI). Study Design: It is a retrospective cohort study. Introduction: Stress cardiac MRI is a highly accurate and

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

open access: yesMolecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

Aspectos relevantes de la S-adenosilhomocisteína hidrolasa relacionados con el metabolismo de la S-adenosilhomocisteína Relevant aspects of S-adenosylhomocysteine hydrolase related to the metabolism of S-adenosylhomocysteine

open access: yesRevista Cubana de Investigaciones Biomédicas, 2006
Se realizó una revisión de la S-adenosil metionina, considerado como el donante fundamental de grupos metilo en el organismo. Por una reacción de transmetilación es obtenida la S-adenosil homocisteína, que es un potente inhibidor de transmetilasas ...

Research progress on adenosine in central nervous system diseases

open access: yesCNS Neuroscience & Therapeutics, 2019
As an endogenous neuroprotectant agent, adenosine is extensively distributed and is particularly abundant in the central nervous system (CNS). Under physiological conditions, the concentration of adenosine is low intra‐ and extracellularly, but increases

Adenosine and anergy

open access: yesAutoimmunity, 2007
T cells must integrate multiple environmental cues when deciding whether to mount an immunogenic or tolerogenic response. Since not all self-reactive T cells are eliminated during thymic development, mechanisms of peripheral tolerance such as T cell anergy contribute to preventing autoimmunity. Recent studies have implicated extracellular adenosine and

Loss of proton‐sensing GPR4 reduces tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
G protein‐coupled receptor 4 (GPR4) is a pH‐sensing receptor activated by acidic pH. GPR4 expression is increased in patients with inflammatory bowel disease who are at high risk of developing colorectal cancer. In mouse models, loss of GPR4 attenuated tumor progression. This correlated with increased IL2 and natural killer cell activity.

Profiling the effect of low frequency mechanical vibration on the metabolic and oxidative stress responses of A431 carcinoma

open access: yesFEBS Open Bio, EarlyView.
20 Hz mechanical vibration induced A431 cancer cells' apoptosis without such effect on other healthy cell lines of L929 and C2C12. Lowered glucose consumption is observed specifically in A431. The expressions of ROS, HMGB1, and HSP1 levels initially increase and subsequently decrease in the cancer cell line, as opposed to L929 and C2C12, which ...

Neuronal Adenosine A1 Receptor is Critical for Olfactory Function but Unable to Attenuate Olfactory Dysfunction in Neuroinflammation

open access: yesFrontiers in Cellular Neuroscience, 2022
Adenine nucleotides, such as adenosine triphosphate (ATP), adenosine diphosphate (ADP), as well as the nucleoside adenosine are important modulators of neuronal function by engaging P1 and P2 purinergic receptors.
