Angiotensin II type 1 receptor-mediated peroxide production in human macrophages.
Our previous experiments demonstrated upregulation of the renin-angiotensin system in macrophages, including angiotensin II type 1 (AT1) and type 2 (AT2) receptors, during transformation from monocytes. We investigated the role of angiotensin II in oxidative stress of monocytes/macrophages, which plays a role in the advance of atherosclerosis. THP1, a human monocytic leukemia cell line, was dif...
متن کاملAngiotensin II promotes melanogenesis via angiotensin II type 1 receptors in human melanocytes.
Angiotensin II (AngII) is a hormone with long-established cardiovascular actions. Previous studies have revealed an additional role for AngII in the regulation of cutaneous wound healing. To evaluate the association between AngII and abnormal pigmentation of cutaneous wound healing, the present study used human melanocytes to investigate the effects of AngII on melanogenesis, and to elucidate t...
متن کاملEpidermal growth factor-enhanced human angiotensin II type 1 receptor.
The human angiotensin II type 1 (AT1) receptor gene was isolated and its promoter function analyzed by deletion mutant promoter/luciferase constructs in transfected Cos 7 cells. We found that epidermal growth factor enhanced the human AT1 promoter activity twofold to threefold. The region between -227 and -366 bp from the 5' end of the cDNA was mapped for a base sequence responsive to the epide...
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 کاملAngiotensin II type 1 receptor A1166C gene polymorphism is associated with an increased response to angiotensin II in human arteries.
An adenine/cytosine (A/C) base substitution at position 1166 in the angiotensin II type 1 receptor (AT(1)R) gene is associated with the incidence of essential hypertension and increased coronary artery vasoconstriction. However, it is still unknown whether this polymorphism is associated with a difference in angiotensin II responsiveness. Therefore, we assessed whether the AT(1)R polymorphism i...
