Angiotensin II mediates angiotensin converting enzyme type 2 internalization and degradation through an angiotensin II type I receptor-dependent mechanism.
Angiotensin-converting enzyme type 2 (ACE2) is a pivotal component of the renin-angiotensin system, promoting the conversion of angiotensin II (Ang-II) to Ang-(1-7). We previously reported that decreased ACE2 expression and activity contributes to the development of Ang-II-mediated hypertension in mice. The present study aimed to investigate the mechanisms involved in ACE2 downregulation during...
متن کاملAngiotensin II type 1 receptor blockers.
In the 1970s, a series of observations demonstrated that angiotensin II has deleterious effects on the heart and kidney and that patients with high levels of plasma renin activity are at a higher risk of developing stroke or myocardial infarction than those with low plasma renin activity.1,2 Thereafter, the development of pharmacological probes that block the renin-angiotensin system helped def...
متن کاملLow-dose angiotensin II increases free isoprostane levels in plasma.
Chronic intravenous infusion of subpressor doses of angiotensin II causes blood pressure to increase progressively over the course of several days. The mechanisms underlying this response, however, are poorly understood. Because high-dose angiotensin II increases oxidative stress, and some compounds that result from the increased oxidative stress (eg, isoprostanes) produce vasoconstriction and ...
متن کاملAngiotensin II type 2 receptor gene transfer elicits cardioprotective effects in an angiotensin II infusion rat model of hypertension.
The role of the angiotensin II type 2 receptor (AT2R) in cardiovascular physiology remains elusive. We have developed an in vivo lentiviral vector-mediated gene transfer system to study the physiological functions of the AT2R. Our objectives in this study were to determine whether the AT2R influences cardiac hypertrophy and myocardial and perivascular fibrosis in a nongenetic rat model of hyper...
متن کاملAngiotensin II type 1 receptor-mediated augmentation of urinary excretion of endogenous angiotensin II in Val5-angiotensin II-infused rats.
Rats infused chronically with Val(5)-Angiotensin (Ang) II exhibit increased urinary excretion of endogenous Ile(5)-Ang II by the 12th day of infusion, suggesting the stimulation of endogenous Ang II formation by Val(5)-Ang II infusion. The present study determined the time course of increased urinary Ang II excretion and the effects of Ang II type 1 receptor blockade (candesartan, 2 mg/kg per d...
