Arresting angiotensin type 1 receptors
Trends in Endocrinology and Metabolism, 2003The type 1 angiotensin (AT(1)) receptor mediates the homeostatic and pathological actions of the peptide hormone, angiotensin II. With regard to the processes that activate and deactivate seven-transmembrane-spanning, G-protein-coupled receptors (GPCRs), AT(1) receptors are among the most widely studied, serving as prototypes for GPCRs that bind and ...

Angiotensin (1???7) is an antagonist at the type 1 angiotensin II receptor
Journal of Hypertension, 1994The present study investigated the antagonism of the amino-terminal heptapeptide fragment of angiotensin II ([des-Phe8]-angiotensin II; Ang(1-7)) to angiotensin II (Ang II) both in vitro in rabbit aortae and in vivo in rats.In rabbit isolated endothelium intact aortic rings Ang(1-7) caused a concentration-related rightward displacement of the Ang II ...

Regulation of Vascular Type 1 Angiotensin Receptors by Cytokines
Hypertension, 1997AbstractAlthough various cytokines are known to be expressed in atherosclerotic lesions, it is not known how these cytokines affect receptors for the peptide hormone angiotensin II (Ang II). We therefore examined the effects of interleukin-1α (220 U/mL [10 ng/mL]), tumor necrosis factor-α (280 U/mL [100 ng/mL]), and interferon gamma (100 U/mL) on Ang ...

Inhibiting angiotensin type 1 receptors as a target for diabetes
Expert Opinion on Therapeutic Targets, 2008Angiotensin type 1 (AT1) receptor blockers (ARBs) are used to treat hypertension and related end-organ damage. ARBs have been recognised as regulators of glucose- and lipid metabolism. Clinical trials demonstrated that AT1 receptor antagonism lowers the risk for type 2 diabetes compared with other antihypertensive therapies.

Biased Agonism of the Angiotensin II Type 1 Receptor
Mini-Reviews in Medicinal Chemistry, 2012G protein-coupled receptors (GPCRs) can be activated by multiple ligands and exhibit the capacity to couple to numerous intracellular signal transduction pathways. This property allows GPCRs to be modulated by biased agonists that selectively activate specific subsets of GPCR-regulated cellular signaling proteins.

Type 1 angiotensin II receptors of adrenal tumors
Steroids, 1995The present study was designed to clarify the transcriptional regulation of the human type 1 angiotensin II receptor (AT1) gene and its pathophysiological roles in steroidogenesis by adrenal tumors. A cDNA encoding type 1 angiotensin II receptor (AT1) was isolated from a human liver cDNA library encoding a protein of 359 amino acids with seven ...

Angiotensin type-1 receptor blockers in heart failure
Progress in Cardiovascular Diseases, 2002Chronic heart failure is a common condition with a poor prognosis, usually associated with poor exercise tolerance and debilitating symptoms despite optimal modern therapy. Standard therapy includes diuretics, digoxin, angiotensin-converting enzyme inhibitors (ACEIs) and beta-blockers.

Endocytosis and signaling of angiotensin II type 1 receptor
2023A vasoactive octapeptide angiotensin II (Ang II) hormone is the key regulator of the renin-angiotensin system (RAS). It binds with the two different plasma membrane receptors like angiotensin II type 1 (AT1) and type 2 (AT2) and consequence various biological responses occur. Further, AT1 has two subtypes such as AT1A and AT1B.

Expression of type 1 angiotensin II receptors in human aldosteronomas
Endocrine Research, 1995Type 1 angiotensin II (AII) receptors (AT1 receptors), besides stimulation of aldosterone secretion, seem to transduce the growth factor-like activity of AII on glomerulosa cells. Although a local renin-angiotensin system and AII synthesis have been found in human adrenals and aldosteronomas, it is unclear whether aldosteronomas express AT1 receptors ...

Stimulation of ANP by angiotensin-(1-9) via the angiotensin type 2 receptor
Life Sciences, 2013Angiotensin-(1-9) [Ang-(1-9)] and Ang-(1-7) are cleaved by Ang converting enzyme 2 forming Ang I and Ang II, respectively, and the truncated Angs play a role in regulating atrial natriuretic peptide (ANP) secretion. Previously, we found that Ang-(1-7) stimulates ANP secretion via the Mas receptor.
