title: Regional differences in prostacyclin formation by the kidney. Prostacyclin is a major prostaglandin of renal cortex.
abstract: Microsomes prepared from rabbit renal cortex were found to synthesize substantial amounts of 6-ketoprostaglandin F1alpha from prostaglandin G2 or arachidonic acid during an incubation. In contrast, no 6-ketoprostaglandin F1alpha was formed by renal medullary microsomes which synthesize predominantly prostaglandin E2. Mass spectral confirmation of the structure of 6-ketoprostaglandin F1alpha from these incubations demonstrates the ability of the renal cortex to synthesize prostacyclin.
