Previous results from our laboratory have shown that in the isolated perfused juxtaglomerular apparatus, nonselective inhibitors of cyclooxygenase (COX) activity prevent the stimulation of renin secretion by a reduction in luminal NaCl concentration at the macula densa. The present studies were performed to examine which COX isoform is involved in NaCl-dependent renin secretion. In the absence of COX inhibitors, a reduction in luminal NaCl (from Na 141/Cl 120 mM to Na 26/Cl 7 mM) caused an…

Physiology and pathophysiology of the renal Na-K-2Cl cotransporter (NKCC2).

An overview of the current knowledge with respect to the general functions ofNKCC2, the modulation of its transport activity by different regulatory mechanisms, and new developments in the pathophysiology of NKCC2-dependent renal NaCl transport is provided.

Regulation of Cyclooxygenase- and Cytochrome P450-Derived Eicosanoids by Heme Oxygenase in the Rat Kidney

It is concluded that HO isoform expression is segmented within the kidney and along the nephron and that treatment with an HO-1 inducer suppressed the levels of CYP4A and COX-2 proteins in a tissue-specific manner with concomitant effects on their activity.

Epithelial COX-2 Expression Is Not Regulated By Nitric Oxide in Rodent Renal Cortex

It is concluded that alterations of distal tubular NaCl concentration and presumably NaCl transport induce changes in epithelial COX-2 expression that does not depend on presence of co-expressed NOS1, and it seems unlikely that NO is part of a signal transduction chain between tubular chloride sensing and the modulating effects of prostaglandins in tubulo-vascular information transfer.

The isolated perfused rat kidney was used to study the role of PG as a mediator of renin secretion when extracellular calcium was decreased and after activation of each of the intrarenal receptors.

Effect of prostanoids on renin release from rabbit afferent arterioles with and without macula densa.

The hypothesis that prostaglandin (PG) I2 and/or its metabolite(s), which are synthesized in the afferent arteriole (AF), stimulate renin release by acting directly on the AF while PGE2 stimulates reninRelease indirectly via the macula densa is tested.

Direct demonstration of macula densa-mediated renin secretion.

In this preparation, influences from renal nerves and local hemodynamic effects are eliminated, a decrease in the tubular sodium chloride concentration at the macula densa results in a prompt stimulation of the renin release rate.

Coordinate expression of cyclooxygenase-2 and renin in the rat kidney in renovascular hypertension.

Data from the kidneys of rats with two-kidney, one-clip renovascular hypertension or sham operation are consistent with a role for macula densa cyclooxygenase-2 in the regulation of renin in renov vascular hypertension.

The coordinated regulation of NOS I and COX-2 expression in MD cells and of renin expression in granular cells suggests that control of juxtaglomerular regulation of gene transcription or mRNA metabolism may be another consequence of a chronic alteration in MD NaCl concentration.

Cyclooxygenase-2 is associated with the macula densa of rat kidney and increases with salt restriction.

The intrarenal distribution of COX-2 and its increased expression in response to sodium restriction suggest that in addition to its proposed role in inflammatory and growth responses, this enzyme may play an important role in the regulation of salt, volume, and blood pressure homeostasis.

Cyclooxygenase-2 mediates increased renal renin content induced by low-sodium diet.

Increased renal renin content in response to dietary sodium restriction appears to require the induction of cyclooxygenase-2, while neuronal nitric oxide synthase appears to affect basal but not stimulated renal renIn content.

Prostaglandin stimulation of renin release: independence of beta-adrenergic receptor activity and possible mechanism of action.

These experiments show that PGE2 causes stimulation of renin release by a direct effect on the JG cell, and the renin-releasing effect of P GE2 does not depend upon the beta-adrenergic receptors but may be mediated through cAMP.

Prostaglandin in renin release during sodium deprivation.

It is concluded that the increase in PRA, possibly resulting from macula densa receptor stimulation, during dietary Na deprivation is dependent on prostaglandin synthesis.
