Prostaglandin E2 production by glomeruli and collecting tubules isolated from rat kidney.
The effects of vasopressin, angiotensin II, and calcium ionophore A23187 were examined and compared on endogenous prostaglandin E2 (PGE2) production, in the absence of exogenous arachidonate, by glomeruli and cortical and medullary collecting tubules freshly prepared from rat kidney. Angiotensin II stimulated PGE2 production in the glomeruli but not in the collecting tubules. Vasopressin at con...
متن کاملLipoxygenase Activity in Rat Cells , and Cortical Tubules * Kidney Glomeruli , Glomerular Epithelial
We examined the possibility that renal glomerular and cortical tubular tissue has lipoxygenase activity in addition to the well established cyclo-oxygenase pathway of arachidonic acid metabolism. Homogenized rat kidney glomeruli, in the presence of meclofenamate (33 PM) and divalent cation ionophore A23187 (3 PM), metabolized octatritiated arachidonic acid to 12-hydroxyeicosatetraenoic acid and...
متن کاملKidney Cortex Tubules
Triacylglycerol metabolism has been studied in kidney cortex tubules from starved rats, prepared by collagenase treatment. Triacylglycerol was determined by a newly developed fully enzymic method. Incubation of tubules in the absence of fatty acids led to a decrease of endogenous triacylglycerol by about 50% in 1 h. Addition of albuminbound oleate or palmitate resulted in a steady increase of t...
متن کاملKidney Proximal Tubules
The aim of this study was to evaluate the role of the kidney in mediating the signals involved in adaptive changes in luminal Na+/H+ exchange and basolateral Na+:HCOcotransport systems in metabolic acidosis. Proximal tubular suspensions were prepared from rabbit kidney cortex and incubated in acidic (A) or control (C) media (pH 6.9 vs 7.4, 5% C02) for 2 h. Brush border membrane (BBM) and basola...
متن کاملSegmental expression of somatostatin receptor subtypes sst(1) and sst(2) in tubules and glomeruli of human kidney.
Somatostatin is known to modulate mesangial and tubular cell function and growth, but the somatostatin receptor (sst) subtypes responsible for these effects have not been defined. There are at least five different sst receptor subtypes (sst(1)-sst(5)). We used RT-PCR to demonstrate that normal human kidney consistently expresses mRNA for sst(1) and sst(2) (9 of 9 donors). Some donors expressed ...
