nucleotidase/breast neoplasms

Ecto-5'-nucleotidase (CD73) was overexpressed in malignancies of epithelial origin and was involved in a variety of cellular processes such as cytoprotection and anti-inflammation. In the present study, human mammary T-47D cells were transfected with pcDNA-NT5E to establish a CD73 overexpressed cell

We have measured sialyltransferase, galactosyltransferase, and fucosyltransferase as sell as 5'-nucleotidase in the serum of breast cancer patients. Serum sialyltransferase values in 65 normal healthy females ranged from 2.6 to 8.5 units, with a mean of 5.4. In 25 women with operable primary breast

OBJECTIVE The purpose is to understand the expression of ecto-5'-nucleotidase (eN), an adenosine producing enzyme with potential roles in angiogenesis, growth, and immunosuppression, in estrogen receptor (ER)-negative and -positive breast cancer. METHODS We investigated the regulation of eN

Tumor stem cell theory may well explain a variety of malignant behaviors of tumors. Cells undergoing epithelial-mesenchymal transition (EMT) share many characteristics with tumor stem cells. Our previous studies showed that extracellular -5'- nucleotidase (CD73), one of the important surface markers

We have modified a manual assay method for the determination of serum 5'-nucleotidase so that the reaction product, phosphate, is assayed colorimetrically using a continuous flow system. The contribution of non-specific phosphatase enzymes is assessed in the presence of nickel ions which

OBJECTIVE Associated with many molecules, metastasis includes cell adhesion to extracellular matrix, migration towards specific direction and invasion into local vessel of distant organs. The purpose of the present study was to evaluate the role of ecto-5'-nucleotidase (eN, ecto-5-NT, CD73)

Serum derived from the breast cancer patient included in this study was found to be a rich source of 5'-nucleotidase. In addition, it also contains nonspecific alkaline phosphatase. The properties of 5'-nucleotidase were studied by eliminating the interference of serum non-specific alkaline

Sialyltransferase and 5'-nucleotidase were measured in the sera of 135 women with breast cancer: 53 undergoing mastectomy for primary cancer and 83 receiving different modalities of palliative therapy for metastatic disease. The objective of this study was to determine whether these enzyme levels

The cytosolic 5'-nucleotidase cN-II is a highly conserved enzyme implicated in nucleotide metabolism. Based on recent observations suggesting additional roles not directly associated to its enzymatic activity, we studied human cancer cell models with basal or decreased cN-II expression. We developed

Metastasis is a leading cause of mortality and morbidity in breast cancer. Recently, dramatic overexpression of ecto-5'-nucleotidase (CD73), a glycosylphosphatidylinositol-anchored cell surface protein has been found in estrogen receptor-negative [ER (-)] breast cancer cell lines and in clinical

Ecto-5'-nucleotidase (CD73) is an essential enzyme that generates adenosine, an essential molecule for cell growth. CD73 increases significantly in many breast cancers. In this study, alpha,beta-methylene adenosine-5'-diphosphate (APCP), a specific CD73 inhibitor was used to block the hydrolase's

To identify the role and to explore the mechanism of extracellular 5'-nucleotidase (CD73) in human breast cancer growth, CD73 expression was measured firstly in breast cancer tissues and cell lines, and then interfered with or over-expressed by recombinant lentivirus in cell lines. Impacts of CD73

Serum levels of adenosine deaminase (ADA), 5-nucleotidase (5'-NT) and alkaline phosphatase (ALP) were studied in 25 patients of carcinoma breast and 25 normal subjects. Adenosine deaminase was found to be the better probable parameter for the detection of cancer and to assess the development of

The activities of NTPDase (EC 3.6.1.5, apyrase, CD39) and 5'-nucleotidase (EC 3.1.3.5, CD73) enzymes were analyzed in platelets from breast cancer patients. Initially, patients were compared in terms of length (years) of tamoxifen use. The following groups were studied: breast cancer patients who

Recently, we have found dramatic overexpression of ecto-5'-nucleotidase (or CD73), a glycosylphosphatidylinositol-anchored component of lipid rafts, in estrogen receptor-negative [ER-] breast cancer cell lines and in clinical samples. To find out whether there is a more general shift in expression
