BACKGROUND: It was recently reported Lipoxins (LXs) had protective effects on fibrous diseases, and renin-angiotensin-aldosterone system (RAAS) had played vital and bidirectional roles in hepatic fibrosis. In this paper, a hepatic fibrosis model, induced by carbon tetrachloride (CCL4) in rats, was used to observe the relations between RAAS and LXs, as well as to further explore the alternative anti-fibrosis mechanisms of LXs. METHODS: The model was evaluated by morphological observations and biochemical assays...

The effects of angiotensin-converting enzyme (ACE) inhibition by an antihypertensive drug, captopril, and milk casein-derived ACE-inhibiting bioactive tripeptide isoleucine-proline-proline (Ile-Pro-Pro), on local renin-angiotensin system (RAS) and glucocorticoid production in the intestine were studied in the dextran sodium sulfate induced colitis in mice. Mice received water or 3% dextran sodium sulfate with or without either 15.7 mg/l captopril or 833 mg/l Ile-Pro-Pro for 7 days. Captopril and Ile-Pro-Pro were found to have distinct effects on local renin-angiotensin system and mRNA expression of glucocorticoid synthesis components in colon in vitro...

Left ventricular aneurysms and pseudoaneurysms are complications of myocardial infarction. With advances in percutaneous coronary intervention, development of thrombolytic agents, and early initiation of treatment with angiotensin-converting enzyme inhibitors to decrease afterload and inhibit left ventricular remodeling, these complications have become much less common. Here, we report an incidental finding of a giant aneurysm of the left ventricle with associated thrombus and mural calcifications in an elderly male patient who presented to his primary care physician for abdominal pain and denied any prior coronary artery disease...

Mas receptor (MasR) is a G protein-coupled receptor proposed as a candidate for mediating the angiotensin (Ang)-converting enzyme 2-Ang (1-7) protective axis of renin-angiotensin system. Because the role of this receptor is not definitively clarified, determination of MasR tissue distribution and expression levels constitutes a critical knowledge to fully understanding its function. Commercially available antibodies have been widely employed for MasR protein localization and quantification, but they have not been adequately validated...

The vasoactive proline-rich oligopeptide termed BPP-BrachyNH2 (H-WPPPKVSP-NH2) induces in vitro inhibitory activity of angiotensin I-converting enzyme (ACE) in rat blood serum. In the present study, the removal of N-terminal tryptophan or C-terminal proline from BPP-BrachyNH2 was investigated in order to predict which structural components are important or required for interaction with ACE. Furthermore, the toxicological profile was assessed by in silico prediction and in vitro MTT assay. Two BPP-BrachyNH2 analogues (des-Trp(1)-BPP-BrachyNH2 and des-Pro(8)-BPP-BrachyNH2) were synthesized, and in vitro and in silico ACE inhibitory activity and toxicological profile were assessed...

Angiotensin-converting enzyme-2 (ACE2) is downregulated in hypertensive nephropathy. The present study investigated the mechanisms whereby loss of ACE2 promoted angiotensin II-induced hypertensive nephropathy in ACE2 gene knockout mice. We found that compared with wild-type animals, mice lacking ACE2 developed much more severe hypertensive nephropathy in response to chronic angiotensin II infusion, including higher levels of blood pressure, urinary protein excretion, serum creatinine, and progressive renal fibrosis and inflammation...

Crescentic glomerulonephritis (GN) is a devastating disease with rapidly progressive deterioration in kidney function, which, histologically, manifests as crescent formation in most glomeruli. We previously found that crescents derive from the aberrant proliferation and migration of parietal epithelial cells (PECs)/progenitor cells, and that the angiotensin (ang) II/ang II type-1 (AT1) receptor pathway may participate, together with the stromal cell-derived factor-1 (SDF-1)/CXCR4 axis, in the development of those lesions...
