Angiotensin II Type 1 Receptor–associated Protein

Regulation of angiotensin II type 1 receptor mRNA and protein in angiotensin II-induced hypertension.

Chronic elevations of circulating angiotensin II (Ang II) cause sustained hypertension and enhanced accumulation of intrarenal Ang II by an AT1 receptor-dependent process. The present study tested the hypothesis that chronic elevations in circulating Ang II regulate AT1 mRNA and protein expression in a tissue-specific manner. Sprague-Dawley rats were infused with Ang II (80 ng/min) or vehicle s...

Angiotensin 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...

Angiotensin II Type 1 Receptor‐Associated Protein Regulates Kidney Aging and Lifespan Independent of Angiotensin

BACKGROUND The kidney is easily affected by aging-associated changes, including glomerulosclerosis, tubular atrophy, and interstitial fibrosis. Particularly, renal tubulointerstitial fibrosis is a final common pathway in most forms of progressive renal disease. Angiotensin II type 1 receptor (AT1R)-associated protein (ATRAP), which was originally identified as a molecule that binds to AT1R, is ...

Angiopoietin-like protein 2 expression is suppressed by angiotensin II via the angiotensin II type 1 receptor in rat cardiomyocytes

The present study aimed to determine the inhibitory effects of angiotensin II (AngII) on angiopoietin‑like protein 2 (Angptl2) in rat primary cardiomyocytes, and to investigate the potential association between angiotensin II type 1 receptor (AT1R) and these effects. Cardiomyocytes were isolated from 3-day-old Wistar rats, and were cultured and identified. Subsequently, the expression levels of...
