Angiotensin II type 2 receptor mediates programmed cell death.
The function of the recently discovered angiotensin II type 2 (AT2) receptor remains elusive. This receptor is expressed abundantly in fetus, but scantily in adult tissues except brain, adrenal medulla, and atretic ovary. In this study, we demonstrated that this receptor mediates programmed cell death (apoptosis). We observed this effect in PC12W cells (rat pheochromocytoma cell line) and R3T3 ...
متن کاملAngiotensin 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 1a receptor mediates doxorubicin-induced cardiomyopathy.
Although the serious cardiotoxicity of doxorubicin (DOX), a useful chemotherapeutic agent, limits the use of this agent, the mechanism of DOX-induced cardiomyopathy remains unclear. Since accumulating evidence suggests that activation of the renin-angiotensin system is involved in the development of various types of cardiovascular remodeling, we examined the role of angiotensin II (Ang II) in D...
متن کاملAngiotensin II type 1 receptor-dependent oxidative stress mediates endothelial dysfunction in type 2 diabetic mice.
The mechanisms underlying the effect of the renin-angiotensin-aldosterone system (RAAS) inhibition on endothelial dysfunction in type 2 diabetes are incompletely understood. This study explored a causal relationship between RAAS activation and oxidative stress involved in diabetes-associated endothelial dysfunction. Daily oral administration of valsartan or enalapril at 10 mg/kg/day to db/db mi...
متن کاملThe angiotensin II receptor 2 is expressed and mediates angiotensin II signaling in lung fibrosis.
Idiopathic pulmonary fibrosis (IPF) is a severe interstitial lung disease unresponsive to currently available therapies. In IPF, initial alveolar epithelial cell damage leads to activation of fibroblast-(myo)fibroblasts, which deposit an increased amount of a collagen-rich extracellular matrix. Angiotensin II (ANGII) signaling, mediated via angiotensin II receptor type 1 (AGTR1) or type 2 (AGTR...
