An oral formulation of angiotensin-(1-7) produces cardioprotective effects in infarcted and isoproterenol-treated rats.

In this study we evaluated the cardiac effects of a pharmaceutical formulation developed by including angiotensin (Ang)-(1-7) in hydroxypropyl β-cyclodextrin (HPβCD), in normal, infarcted, and isoproterenol-treated rats. Myocardial infarction was produced by left coronary artery occlusion. Isoproterenol (2 mg/kg, IP) was administered daily for 7 days.

Time-dependent migration of systemically delivered bone marrow mesenchymal stem cells to the infarcted heart.

In this study the time course of homing and the body distribution of systemically delivered bone marrow mesenchymal stem cells (BM-MSCs) after myocardial infarction (MI) were evaluated. BM-MSCs were isolated from Wistar rats, expanded in vitro, and their phenotypical characterization was performed by flow cytometer. Rats were randomly divided into three groups: control, sham MI, and MI.

The nonpeptide angiotensin-(1-7) receptor Mas agonist AVE-0991 attenuates heart failure induced by myocardial infarction.

The nonpeptide AVE-0991, which has been reported as a selective ligand for the angiotensin-(1-7) [ANG-(1-7)] receptor Mas, has actions similar to those attributed to the cardioprotective product of the renin-angiotensin system, ANG-(1-7). In this study, we evaluated the cardiac effects of AVE-0991 in normal and infarcted male Wistar rats. Myocardial infarction was induced by left coronary artery ligation.
