Inhibitors of the angiotensin-converting enzyme (ACE) decrease angiotensin II production and activate an intracellular signaling cascade that affects gene expression in endothelial cells. Because ACE inhibitors have been reported to delay the onset of type 2 diabetes, we determined ACE signaling-modulated gene expression in endothelial cells and adipocytes. Using differential gene expression an...
Aminopeptidase P (AP-P, EC 3.4.1 1.9) was first identified in pig kidney as an cxopeptidase capable of cleaving the Nterminal amino acid residue from peptides with a penultimate proline. Peptidcs of the X-Pro-Y type were cleaved most readily, and a synthetic substrate, glycyl-prolyl-hydroxyproline (Gly-Pro-Hyp), was originally used to monitor AP-P activity [ I ] . The enzyme has sincc been show...
Evidence for enhanced eNOS function in coronary microvessels during the second window of protection.
Nitric oxide (NO) derived from endothelial NO synthase (NOS) (eNOS) has been identified as a trigger for the second window of protection (SWOP), but its role as a mediator during the SWOP is a matter of debate. Eighteen mongrel dogs were chronically instrumented to measure left ventricular function, coronary blood flow, and wall thickening. Myocardial preconditioning was induced by 10 min coron...
Multiple data suggest that the renin-angiotensin system contributes to the pathogenesis of atherosclerosis. The atherogenic effect of the renin-angiotensin system can only in part be explained by the influence of its effector angiotensin II on blood pressure, smooth muscle cell (SMC) growth, or antifibrinolytic activity. Because chronic inflammation of the vessel wall is a hallmark of atheroscl...
To understand how rapid changes in blood pressure can regulate Na-K-ATPase in the kidney cortex, we tested the hypothesis that a short-term (5 min) decrease in renal perfusion pressure will increase the amount of Na-K-ATPase in the plasma membranes by an angiotensin II-dependent mechanism. The abdominal aorta of anesthetized Sprague-Dawley rats was constricted with a ligature between the renal ...
Angiotensin 1-7 (Ang 1-7) has been reported to induce relaxation which is partially blocked by a kinin receptor antagonist. We investigated the relationship between kinins and angiotensin peptides with use of preconstricted isolated pig coronary arteries. Ang 1-7 alone (up to 10(-5) M) had no relaxant effect. Bradykinin (BK) (10(-10)-10(-7) M) induced transient relaxation, returning to basal to...
The monitoring of the plasmatic concentrations of cardiovascular drugs is crucial for understanding their pharmacokinetics and pharmacodynamics. A simple, sensitive, specific, and high-throughput liquid chromatography/tandem mass spectrometry (LC-MS/MS) method was developed and validated for the simultaneous estimation and pharmacokinetic study of losartan (LOS), losartan carboxylic acid (LCA),...
