The relationship of the renin--angiotensin--aldosterone axis with renal prostaglandin E is complex. Although studies have suggested that these two hormonal systems respond to experimental manipulations in a parallel manner, their interdependence has not been assessed fully during volume expansion. Since studies have demonstrated that in normal man the central hypervolaemia induced by water imme...
Cardiac prostaglandin release was studied in closed-chest dogs during acute coronary occlusion. Aortic and coronary sinus blood was obtained before, and at intervals after, balloon occlusion of the left anterior descending artery in seven dogs. Samples were assayed for prostaglandins F, E, and A by randioimmunoassay. All dogs demonstrated prostaglandin F release, Mean +/- SE postocclusion aorti...
Amounts of prostaglandin E and prostaglandin F have been measured by radioimmunoassay in extracts of renal cortical carcinoma and benign and malignant breast tumours after solvent extraction and column chromatography. 2. Substantial amounts of prostaglandin E were found in extracts of benign and malignant breast tumours and in renal tumours. Much lower amounts of prostaglandin F were present in...
OBJECTIVE Prostaglandin E synthases (PGESs) are being explored as antiinflammatory drug targets as alternatives to cyclooxygenase (COX)-2. Located downstream of the cyclooxygenases, PGESs catalyze PGE(2) formation, and deletion of microsomal (m)-PGES-1 abrogates inflammation. We sought to characterize the developmental expression of COX and PGES in zebrafish. METHODS AND RESULTS We cloned zeb...
Three prostaglandin-metabolizing enzymes were detected in human serum. One enzyme was a dehydrase that converted prostaglandin E to prostaglandin A, the second was a prostaglandin A isomerase that converted prostaglandin A to prostaglandin C and the third was a prostaglandin C isomerase that converted prostaglandin C to prostaglandin B. All three were inactivated by sulfhydryl blocking agents. ...
Prostaglandin E(2) plays an important role in the maintenance of gastric mucosal integrity. The level of biologically active prostaglandin E(2) in the tissue is regulated by the balanced expression of its synthetic enzymes, such as cyclooxygenase, and its catabolic enzyme, 15-hydroxyprostaglandin dehydrogenase. We examined the effect of rebamipide, a mucoprotective drug, on prostaglandin E(2) p...
