Overexpression of angiotensin II type I receptor in cardiomyocytes induces cardiac hypertrophy and remodeling.
Angiotensin II (AII) is a major determinant of arterial pressure and volume homeostasis, mainly because of its vascular action via the AII type 1 receptor (AT1R). AII has also been implicated in the development of cardiac hypertrophy because angiotensin I-converting enzyme inhibitors and AT1R antagonists prevent or regress ventricular hypertrophy in animal models and in human. However, because ...
متن کاملP-218: Investigation of Association between Angiotensin II Type 1 and 2 Receptor (AT1R & AT2R) Gene Polymorphisms and Susceptibility to Pre-Eclampsia (PE) in Iranian Women
Background: Hypertension during pregnancy period along with the presence of protein in the urine, after the 20th weeks of gestation is called preeclampsia (PE). About five percent of all pregnancies are manifested with PE and its exact etiology has still remained unknown. The renin-angiotensin system (RAS) has an important role in the regulation of blood pressure during pregnancy and so pathoph...
متن کاملAngiotensin type 2-receptor (AT2R) activation induces hypotension in apolipoprotein E-deficient mice by activating peroxisome proliferator-activated receptor-γ.
Angiotensin II (Ang II) modulates blood pressure and atherosclerosis development through its vascular type-1 (AT1R) and type-2 (AT2R) receptors, which have opposing effects. AT2R activation produces hypotension, and is anti-atherogenic. Targeted overexpression of AT2Rs in vascular smooth muscle cells (VSMCs) indicates that these effects are due to increased nitric oxide (NO) generation. However...
متن کاملAngiotensin II type 1 receptor overexpression in podocytes induces glomerulosclerosis in transgenic rats.
Angiotensin II (AngII) is a critical determinant of glomerular function involving both hemodynamic and pressure-independent effects that are insufficiently understood. A novel transgenic rat (TGR) model with overexpression of the human AngII type 1 receptor (hAT1) in podocytes was developed to study the consequences of an increased AT1 signaling on the structure and function of the glomerular f...
متن کاملType 2 angiotensin II receptor is downregulated in cardiomyocytes of patients with heart failure.
BACKGROUND The human heart expresses type 2 angiotensin (AT(2)) receptor, but the function is poorly defined. METHODS In the present study, we investigated (1) the cellular localization of the AT(2) receptor and (2) the relationship between the AT(2) receptor protein expression and the cardiac function of patients with ischemic heart disease. The receptor localization was assessed by immunohi...
