title: Production of prostaglandins and HETE-compounds by isolated-cultivated bovine aortic endothelial cells.
abstract: The main product of AA conversion by BAEC is PGI2. Other PGs were synthesized by confluent cells only in traces with exception of a HHT-like compound which has still to be characterized in more details. A significant release of HETE was only detected when BAEC were destroyed. Under these conditions about 1 pmole/10(5) cells 15- and 12 HETE were released by BAEC. Taken into account the amounts of HETE produced by endothelial cells as well as the partially contradictory activities of 12- and 15-HETE we suggest that an acclerated lipoxygenase activity reflects a lesion of endothelium, but is of minor physiological relevance as compared to the generation of HETE and other eicosanoids by blood cells.
