Evidence for coordinated induction and repression of ecto-5'-nucleotidase (CD73) and the A2a adenosine receptor in a human B cell line [PDF]

open access: yes, 2003
In the human B cell line P493-6 two mitogenic signals, the EpsteinBarr virus nuclear antigen 2 (EBNA2) and myc, can be independently regulated by means of an estrogen receptor fusion construct or an inducible expression vector, respectively.

Estradiol regulation of nucleotidases in female reproductive tract epithelial cells and fibroblasts. [PDF]

open access: yesPLoS ONE, 2013
The use of topical and oral adenosine derivatives in HIV prevention that need to be maintained in tissues and cells at effective levels to prevent transmission prompted us to ask whether estradiol could influence the regulation of catabolic nucleotidase ...

Evaluation of the level of 5'-nucleotidase and some biochemical parameters in the sera of beta-thalassemia patients

open access: yesTikrit Journal of Pure Science, 2023
One of the hydrolytic enzymes that catalyzes the hydrolysis of 5' -nucleotides into ribonucleosides and phosphate is the 5'nucleotidase, which is found in several organs.

ATP as a presynaptic modulator [PDF]

open access: yes, 2000
© 2000 Elsevier Science Inc.There is considerable evidence that ATP acts as a fast transmitter or co-transmitter in autonomic and sensory nerves mostly through activation of ionotropic P2X receptors but also through metabotropic P2Y receptors. By analogy,

Activity-dependent release of Adenosine: a critical re-evaluation of mechanism [PDF]

open access: yes, 2008
Adenosine is perhaps the most important and universal modulator in the brain. The current consensus is that it is primarily produced in the extracellular space from the breakdown of previously released ATP.

Methyl jasmonate elicitation of common bean seedlings induces nucleotidase activity and the expression of several nucleotidase genes in radicles

open access: yesBiologia Plantarum, 2021
Nucleotides are the basic elements of the genetic material, participate in bio-energetic processes, are cofactors and components of secondary metabolites, etc. Nucleotide hydrolases (nucleotidases) are phosphatases that remove the 5'-phosphate group from

ACTIVITY OF AMP DEAMINASE AND 5′-NUCLEOTIDASE IN THE CYTOSOLIC KIDNEY FRACTION OF RATS UNDER THE CONDITIONS OF DIFFERENT PROTEIN AND SUCROSE CONTENT IN A DIET [PDF]

open access: yesBiotechnologia Acta, 2022
Aim. The goal of this work was to evaluate the activity of AMP deaminase and 5′-nucleotidase in the cytosolic kidney fraction of rats under the conditions of different protein and sucrose content in a diet./ Methods. In the study, 10-12 week old white
