Plasma concentrations of angiopoietin-1, angiopoietin-2 and Tie-2 in colon cancer.
BACKGROUND/AIM despite the rapidly accumulating histopathological data reporting differences in the expression of members of the angiopoietin family on the surface of various normal and tumour cells, data for these growth factors in plasma from cancer patients, including colon cancer, are scarce. The aims of the present study were to measure the plasma concentrations of Ang-1, Ang-2 and Tie-2 i...
متن کاملAngiopoietin-1, angiopoietin-2 and Tie-2 expression in eutopic endometrium in advanced endometriosis.
Endometriosis is one of the most common gynaecological disorders, but its aetiology and pathogenesis remain obscure. The refluxed menstrual debris in women with endometriosis may be more prone to implantation, invasion and growth in the peritoneum or ovary through the actions of extracellular proteolysis and angiogenesis. It has been hypothesized that the endometrium from women with endometrios...
متن کاملPlasma angiopoietin-1, angiopoietin-2, and angiopoietin receptor tie-2 levels in congestive heart failure.
OBJECTIVES The goal of this research was to test the hypothesis that plasma angiopoietin (Ang-1), its soluble receptor tie-2, and Ang-2 levels would be abnormal in patients with acute and chronic congestive heart failure (CHF) when compared with healthy controls. BACKGROUND Increased plasma vascular endothelial growth factor (VEGF) in CHF is suggestive of excess angiogenesis-possibly driven b...
متن کاملSonic hedgehog inversely regulates the expression of angiopoietin-1 and angiopoietin-2 in fibroblasts.
Nerves and blood vessels have similar branching patterns and use common morphogenic molecules during development. Recent studies show that sonic hedgehog (Shh), a traditional neurogenic morphogen, is required for embryonic arterial differentiation and can induce angiogenesis. We investigated whether Shh regulates the expression of angiogenic factors. Using NIH3T3 embryonic fibroblast cells, we ...
متن کاملBiologic significance of angiopoietin-2 expression in human hepatocellular carcinoma.
Human hepatocellular carcinoma (HCC) is generally a highly vascular tumor, but the mechanisms of neovascularization that permit rapid growth have not been defined. Angiopoietins (Ang) recently have been identified as ligands for vascular endothelial-specific Tie2 receptor tyrosine kinase and may be important growth factors in the generation of new blood vessels. We investigated Ang expression i...
