Inhibition of Gastric Erosion Formations in Rats by Adenosine, 5 /-Adenosine Monophosphate and 5 /- Adenosine Diphosphate [PDF]

open access: yes, 2009
Gastric erosions were induced in rats with indomethacin, 5-hydoxytryptamine (5-HT) or reserpine. Three adenine compounds adenosine, adenosine, 5 /-adenosine monophosphate (AMP) and 5 /- adenosine diphosphate (ADP) were found to protect against the ...

The role of ectonucleotidases CD39 and CD73 and adenosine signalling in solid organ transplantation

open access: yesFrontiers in Immunology, 2014
Extracellular adenosine is a potent immunomodulatory molecule that accumulates in states of inflammation. Nucleotides such as adenosine triphosphate (ATP) and adenosine diphosphate (ADP) are release from injured and necrotic cells and hydrolysed to ...

The ART of tumor immune escape

open access: yesOncoImmunology, 2022
We recently identified the adenosine-5′-diphosphate (ADP)–ribosyltransferase-1 (ART1) as a novel immune checkpoint expressed by cancer cells. ART1 utilizes free nicotinamide adenine dinucleotide (NAD+) in the tumor microenvironment (TME) to mono-ADP ...

Theranostic Potential of an NAD(P)H‐Activatable Fluorophore: Assessing Cancer Aggressiveness and Triggering Apoptosis

open access: yesAngewandte Chemie, EarlyView.
DE‐CQ, an NAD(P)H‐activatable theranostic probe, enables the quantification of cancer aggressiveness via glucose‐stimulated fluorescence imaging and selectively induces apoptosis. Its multifaceted efficacy is demonstrated across 2D cells, 3D spheroids, and in vivo models.

ANALYSIS OF THE STATE OF PLATELET AGGREGATION IN PREGNANT WOMEN WITH THROMBOPHILIA AND BURDENED OBSTETRIC HISTORY

open access: yesСхідноукраїнський медичний журнал, 2021
The analysis of platelet aggregation in pregnant women with thrombophilia and burdened obstetric history was performed. It has been determined that the development of adverse effects of pregnancy is significantly influenced by conditions such as ...

Free Adenosine Diphosphate as an Intermediary in the Phosphorylation by Creatine Phosphate of Adenosine Diphosphate Bound to Actin

open access: yesJournal of Biological Chemistry, 1967
Abstract Pretreatment of adenosine diphosphate-G-actin solutions with apyrase results in a marked decrease in their rate of polymerization at 0° induced by KCl, creatine phosphate, and creatine kinase. In contrast, apyrase has no effect on the rate of polymerization of ATP-G-actin.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Elevated ecto-5′-nucleotidase: a missing pathogenic factor and new therapeutic target for sickle cell disease

open access: yesBlood Advances, 2018
: Although excessive plasma adenosine is detrimental in sickle cell disease (SCD), the molecular mechanism underlying elevated circulating adenosine remains unclear.

Type III effector activation via nucleotide binding, phosphorylation, and host target interaction. [PDF]

open access: yesPLoS Pathogens, 2007
The Pseudomonas syringae type III effector protein avirulence protein B (AvrB) is delivered into plant cells, where it targets the Arabidopsis RIN4 protein (resistance to Pseudomonas maculicula protein 1 [RPM1]-interacting protein).

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.
