We studied the effects of four products of arachidonate cyclo-oxygenation on a phospholipase C-dependent signal transduction system in cultured rat glomerular mesangial cells. PGF2α, PGE2and the thromboxane A2/endoperoxide analogue U-46619 rapidly increased cytosolic free Ca2+, measured in monolayers loaded with the fluorescent intracellular probe fura-2. Peak responses were dose-dependent and unaffected by chelation of extracellular Ca2+, indicating release from internal stores. The thromboxane A2-receptor antagonist SQ 27,427 selectively inhibited responses to U-46619. The PGI2analogue Iloprost had no effect on cytosolic Ca2+. PGF2α, PGE2and U-46619 also stimulated accumulation of total inositol phosphates during 15 min incubations. We conclude that phospholipase C activation mediates the effects of certain eicosanoids on the glomerular mesangium.
