Fluorine-18-Labeled Nucleotide Analogs Targeting Ecto-5'-Nucleotidase (CD73) for Positron Emission Tomography Imaging of Solid Tumors. [PDF]
Angew Chem Int Ed EnglFluorine‐18‐labeled CD73 inhibitor [18F]PSB‐19427 enables noninvasive PET mapping of CD73 overexpression in triple‐negative breast (TNBC) and pancreatic cancer. For [18F]PSB‐19427, specific binding in human tumor tissues, favorable biodistribution with prolonged blood retention, robust tumor uptake, and superiority to [18F]FDG in a TNBC model ...

Expression of bovine cytosolic 5'-nucleotidase (cN-II) in yeast: nucleotide pools disturbance and its consequences on growth and homologous recombination. [PDF]
PLoS ONE, 2013 Cytosolic 5'-nucleotidase II is a widespread IMP hydrolyzing enzyme, essential for cell vitality, whose role in nucleotide metabolism and cell function is still to be exactly determined.

Comparative Study of 5’- Nucleotidase Test in Various Liver Diseases [PDF]
Journal of Clinical and Diagnostic Research, 2016 Introduction: The liver regulates many important metabolic functions. The 5’-nucleotidase activity is increased in obstructive jaundice, parenchymal liver disease, and hepatic metastases. Aim: This study was conducted to assess the serum levels of 5’-

Extracellular ATP released by osteoblasts is a key local inhibitor of bone mineralisation [PDF]
, 2013 Previous studies have shown that exogenous ATP (>1µM) prevents bone formation in vitro by blocking mineralisation of the collagenous matrix. This effect is thought to be mediated via both P2 receptor-dependent pathways and a receptor-independent ...

Nature, 1952 REIS1–4 has demonstrated the presence of a phosphatase in various tissues specifically hydrolysing 5-nucleotides, for example, adenosine-5-phosphate. One of us has previously reported5 that normal blood serum has a low 5-nucleotidase activity corresponding to about 1/10 of its non-specific alkaline phosphatase activity towards glycerophosphate. In bone

Effects of physical exercise on the functionality of human nucleotidases: A systematic review
Physiological Reports, 2022 Nucleotidases contribute to the regulation of inflammation, coagulation, and cardiovascular activity. Exercise promotes biological adaptations, but its effects on nucleotidase activities and expression are unclear.
