Bovine Aortic Endothelial Cells
As bstract. We examined the effect of bovine aortic endothelial cell culture supernatants upon the generation of procoagulant activity by human blood monocytes. Confluent endothelial monolayers were cultured for up to 96 h. At timed intervals, culture supernatants were collected and incubated for 5 h with lipopolysaccharide-stimulated human peripheral blood mononuclear cells. The procoagulant a...
متن کاملBovine aortic endothelial cells contain an angiotensin-(1-7) receptor.
Angiotensin-(1-7) is a novel peptide of the renin-angiotensin system that counteracts the pressor and proliferative responses to angiotensin II. We now report that cultured bovine aortic endothelial cells contain a saturable, high-affinity [125I]angiotensin-(1-7) binding site with an affinity of 19.3 +/- 10.7 nmol/L and a density of 1351 +/- 710 fmol/mg protein. Angiotensin-(1-7) competed at a ...
متن کاملProstacyclin production by perturbed bovine aortic endothelial cells in culture.
This study reports that endotoxin (Escherichia coli serotype 026:B6) and 12-O-tetradecanoyl-phorbol-13-acetate stimulate cultured bovine aortic endothelial cells to generate prostacyclin. The prostacyclin concentration of the culture medium was measured indirectly by radioimmunoassay for 6-keto-PGF1 alpha. The amount of prostacyclin generated depended on the concentration of endotoxin or phorbo...
متن کاملRenin - Angiotensin Components in Cultured Bovine Aortic Endothelial Cells
Cultured bovine aortic endothelial cells were examined for renin activity by biochemical, immunological, and immunohistochemical techniques. When cell sonicates were incubated with renin substrate, linear generation of angiotensin I was observed (1.12 ± 0.2 ng angiotensin I/10 cells per hr). The effect of pH on this activity was similar to that of bovine renal renin, and renin antibodies inhibi...
متن کاملEthanolamine metabolism in cultured bovine aortic endothelial cells.
The role of extracellular ethanolamine in phospholipid synthesis was examined in cultured bovine aortic endothelial cells. Serine and ethanolamine were both readily accumulated by these cells and incorporated into phospholipid. Exposing cells to extracellular ethanolamine for 4-6 weeks had no effect on cell growth, yet increased the phosphatidylethanolamine content of these cells by 31% as comp...
