In this study, we investigated the potential effects of alloxan-induced diabetes on the activities of the enzymes NTPDase (E.C. 3.6.1.5, apyrase, ATP diphosphohydrolase, ecto/CD39) and 5'-nucleotidase (E.C. 3.1.3.5, CD73) that can control the levels of ADP and adenosine, two substances that regulates platelet aggregation.

The expression level of equilibrative transporters (ENT1, ENT2) decreased and of concentrative transporters (CNT1, CNT2) increased in myocytes isolated from diabetic rat.

|
The activity of ecto-5'-nucleotidase increased 2-fold in diabetic cells resulting in a rise of the activity ratio of ecto-5'-nucleotidase/adenosine deaminase from 28 to 56.These results indicate that in rat cardiomyocytes diabetes alters activities of adenosine metabolizing enzymes in such a way that conversion of AMP to IMP is favored in the cytosolic compartment, whereas the capability to produce adenosine extracellularly is increased.

Adenosine is known to stimulate interleukin (IL)-6 and vascular endothelial growth factor (VEGF) secretion from pituitary TtT/GF folliculostellate [corrected] (FS) cells indicating that it is an important paracrine regulator of anterior pituitary function.

|
Ecto-5'-nucleotidase (CD73), the enzyme that generates adenosine from AMP, was demonstrated by immunocytochemistry in approximately 20% of anterior pituitary cells, and some of these cells colocalized with prolactin and growth hormone.

The activities of the enzymes NTPDase (EC 3.6.1.5, apyrase, CD39) and 5'-nucleotidase (EC 3.1.3.5, CD73) were analyzed in platelets from rats submitted to demyelination by ethidium bromide (EB) and treated with interferon beta (IFN-beta).

We show that hIPCs are mesenchymal stromal cells (MSCs) that adhere to plastic, express CD73, CD90, and CD105, and can differentiate in vitro into adipocytes, chondrocytes, and osteocytes.

Moreover, we find a minor population of CD105(+)/CD73(+)/CD90(+) cells in adult human islets (prior to incubation in vitro) that express insulin mRNA at low levels.

TGF responses are abolished in A1 adenosine receptor-deficient mice, and studies in mice with null mutations in NTPDase1 or ecto-5'-nucleotidase indicate that adenosine involved in TGF is mainly derived from dephosphorylation of released ATP.
|

|
Angiotensin II is a required cofactor for the elicitation of TGF responses, as AT1 receptor or angiotensin-converting enzyme deficiencies reduce TGF responses, mostly by reducing adenosine effectiveness.

There are four major families of ectonucleotidases, nucleoside triphosphate diphosphohydrolases (NTPDases/CD39), ectonucleotide pyrophosphatase/phosphodiesterases (E-NPPs), alkaline phosphatases and ecto-5'-nucleotidase.

After long term cryo-preservation hTGSCs expressed surface antigens CD29, CD73, CD90, CD105, and CD166, but not CD34, CD45 or CD133, which was typical for non-frozen hTGSCs.

Human IPC lack expression of Von Willebrand Factor, CD31, CD34, CD45, and CK19 and CA19.9, demonstrating that hIPC are neither of hematopoietic, endothelial, nor of ductal origin.

The glycosylphosphatidylinositol (GPI)-anchored protein, CD73, is released from adipocytes into microvesicles in response to the lipogenic stimuli, palmitate, the antidiabetic sulfonylurea drug glimepiride, phosphoinositolglycans (PIG), and H(2)O(2).

|
Here microvesicles derived from (preferentially large) rat adipocytes or plasma and harboring the GPI-anchored proteins, Gce1 and CD73, were demonstrated to contain specific transcripts and microRNAs that are both transferred into and expressed in acceptor adipocytes and are involved in the upregulation of lipogenesis and cell size.

|
The transferred transcripts were specific for fatty acid esterification (glycerol-3-phosphate acyltransferase-3, diacylglycerol acyltransferase-2), lipid droplet biogenesis (FSP27, caveolin-1) and adipokines (leptin, adiponectin).

Foxp3(+) regulatory T cells (Tregs) originate in the thymus, but the Treg phenotype can also be induced in peripheral lymphoid organs or in vitro by stimulation of conventional CD4(+) T cells with IL-2 and TGF-β.

Most Treg-typical transcripts were shared by NOD or B6g7 TGF-Tregs, except for a small group of differentially expressed genes, including genes relevant for suppressive activity (Lrrc32, Ctla4, and Cd73).

For the network to normally suppress spontaneous arterial calcification, the "cogs" ENPP1, CD73, and ABCC6 must be present and in working order.

Monogenic ENPP1, CD73, and ABCC6 deficiencies each drive a molecular pathophysiology of closely related but phenotypically different diseases (generalized arterial calcification of infancy (GACI), pseudoxanthoma elasticum (PXE) and arterial calcification caused by CD73 deficiency (ACDC)), in which premature onset arterial calcification is a prominent but not the sole feature.

Using siRNA to silence NT5C2 expression in cultured human myotubes, we observed a 2-fold increase in the AMP/ATP ratio, a 2.4-fold increase in AMPK phosphorylation (Thr(172)), and a 2.8-fold increase in acetyl-CoA carboxylase phosphorylation (Ser(79)) (p < 0.05). siRNA silencing of NT5C2 expression increased palmitate oxidation by 2-fold in the absence and by 8-fold in the presence of 5-aminoimidazole-4-carboxamide 1-β-d-ribofuranoside.
