Stimulation of the synthesis of 15-hydroxyeicosatetraenoic acid (15-HETE) and 6-keto-prostaglandin F/sub 1. cap alpha. / (6-keto-PGF/sub 1. cap alpha. /) by cultured human umbilical veins

These studies were designed to investigate the synthesis of 6-keto-PGF/sub 1..cap alpha../ and 15-HETE in cultured human endothelial cells. The identification of the 15-HETE in these cells was made by UV absorption and gas chromatography/mass spectrometry. Specific radioimmunoassays were developed to quantify the synthesized 6-keto-PGF/sub 1..cap alpha../ and 15-HETE. The release of 15-HETE and 6-keto-PGF/sub 1..cap alpha../ was stimulated by arachidonic acid, histamine or the calcium ionophore A23187. The release of 15-HETE paralleled the release of 6-keto-PGF/sub 1..cap alpha../ and was both concentration-related and time-dependent. Aspirin, ibuprofen and indomethacin inhibited both the formation of 6-keto-PGF/sub 1..cap alpha../ and 15-HETE in similar concentrations. These data indicate that agents which stimulate PGI/sub 2/ synthesis also stimulate the synthesis of 15-HETE. Also, they implicate the cyclooxygenase pathway in the synthesis of 6-keto PGF/sub 1..cap alpha../ and 15-HETE in human endothelial cells.
