The intrinsic in vitro production of prostaglandins (PGs) E2, F2 alpha, 6-keto-F1 alpha, and thromboxane B2 (TxB2) and the conversion of exogenous substrate to PGs and TxB2 by isolated human glomeruli was demonstrated, 6-keto-PGF1 alpha was the major product. This was observed under basal conditions and following incubation with exogenous substrate. Indomethacin (Indo; 10(-4 M) inhibited the conversion of arachidonic acid to PGs and the release of [1-14C]-labeled products from human glomeruli by about 80%. The addition of angiotensin II (AII) to the isolated glomeruli produced, under basal conditions, an almost selective stimulation of 6-keto-PGF1 alpha. Following the prelabeling of glomeruli with 1-14C-arachidonic acid, the increase of glomerular PG formation after AII was added was also only significant for 6-keto-PGF1 alpha. When glomeruli were preincubated with large amounts of non-radiolabeled substrate. AII stimulated PGE2 and 6-keto-PGF1 alpha formation significantly. The data demonstrate PG formation in isolated human glomeruli and show an interaction between AII and the prostaglandin system in this tissue. This interrelationship might have physiologic consequences in the regulation of glomerular hemodynamics.
