OBJECTIVE To analyze the clinical significance of COX-2, GLUT-1 and VEGF expressions in endometrial cancer tissues. METHODS One hundred and eight tissue samples from the patients with endometrial cancer enrolled in our hospital from August 2011 to July 2014 were selected, including 60 normal tissue samples (normal group), 60 neoplastic tissue samples (neoplastic group) and 60 cancer tissue sa...

Abstract--Insulin resistance underlies the pathogenesis of chronic disease, such as diabetes mellitus which has high morbidity and mortality rate. Insulin is a pathological condition when cells fail to respond normally insulin hormone, because signaling pathway disruption. Bound between insulin’s receptor cannot phosphorylate tyrosine activate substrate-1 (IRS-1). This failure decrease Glucose ...

Background. We aimed to explore the prognostic impact of the hypoxia-induced factors (HIFαs) 1 and 2, the metabolic HIF-regulated glucose transporter GLUT-1, and carbonic anhydrase IX (CAIX) in non-gastrointestinal stromal tumor soft tissue sarcomas (non-GIST STS). Methods. Duplicate cores with viable tumor tissue from 206 patients with non-GIST STS were obtained and tissue microarrays were con...

For various types of tumor therapy, it is suggested that co-targeting of tumor microenvironment, mainly tumor vasculature, mediates tumor response mechanisms. Immunohistochemistry for glucose transporter-1 (GLUT-1), carbonic anhydrase-IX (CAIX), Ki-67, and von Willebrand factor VIII for microvessel density (MVD) were performed on formalin-fixed paraffin-embedded samples of canine oral malignant...

Placental malaria, especially when complicated with intervillositis, can cause fetal growth restriction. Transplacental glucose transport by glucose transporter isoform 1 (GLUT-1) on the syncytiotrophoblast microvillous and basal plasma membranes regulates fetal growth. We found that GLUT-1 expression in the microvillous plasma membrane of Plasmodium falciparum-negative placenta biopsy specimen...

OBJECTIVES: The objective of this study was to evaluate the usefulness of F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) and the relationships among the expressions of hypoxia-inducible factor-1α (HIF-1α), glucose transporter-1 (Glut-1) and vascular endothelial growth factor (VEGF), histological type, other clinical factors and FDG uptake in thymic epithelial...

Oral squamous cell carcinoma (OSCC) is a malignancy of the oral cavity with poor prognosis. Dysregulation in glycolytic pathways involving glucose transporters (GLUT) has been implicated Furthermore, GLUT expression cancer cells regulated by several miRNAs. However, there lack data about miRNA involved regulation OSCC. The objective to evaluate role Data sources include PubMed (MEDLINE), Scopus...

The expression of glucose transporters 1, 2, 3 and 4 was evaluated in human oocytes and polyploid preimplantation embryos. Only glucose transporter 1 (GLUT-1) isoform was detected in oocytes and in 2-12-cell stage embryos. Glucose uptake was markedly increased in embryos as compared to oocytes (19.7 +/- 3.4 pmol/min/embryo and 2.3 +/- 0.3 pmol/min/oocyte), and GLUT-1 was inhibited by cytochalas...

Starvation (48 h) decreased the concentration of mRNA of the insulin-responsive glucose transporter isoform (GLUT 4) in interscapular brown adipose tissue (IBAT) (56%) and tibialis anterior (10%). Despite dramatic [7-fold (tibialis anterior) and 40-fold (IBAT)] increases in glucose utilization after 2 and 4 h of chow re-feeding, no significant changes in GLUT 4 mRNA concentration were observed ...
