Angiotensin (Ang)-(1-7) ameliorates vascular injury by increasing nitric oxide (NO) bioavailability. Evidence that Ang-(1-7) attenuates the development of atherosclerosis through a NO-dependent mechanism is still missing. Moreover, it has been postulated that Ang-(1-7) may mediate its effects by other mechanisms than Mas receptor activation. To investigate Ang-(1-7)-dependent Mas receptor function, we treated apoE-KO and apoE/Mas-KO mice chronically with Ang-(1-7) (82 μg/kg per hour) or saline for 6 weeks...

Despite advances in anti-hypertensive therapeutics, at least 15-20% of hypertensive patients have resistant hypertension through mechanisms that remain poorly understood. In this study, we provide a new mechanism for regulation of blood pressure (BP) in the central nervous system (CNS) by the (pro)renin receptor (PRR), a recently identified component of the renin-angiotensin system (RAS) that mediates angiotensin II (Ang II) formation in the CNS. Although the PRR also mediates Ang II-independent signaling, the importance of these pathways in BP regulation is unknown...

The present study was designed to determine the effects of senescence and angiotensin II (Ang II) on expression and processing of amyloid precursor protein (APP) in human brain microvascular endothelial cells (BMECs). Senescence caused a decrease in APP expression thereby resulting in reduced secretion of soluble APPα (sAPPα). In contrast, β-site APP cleaving enzyme (BACE1) expression and production of amyloid β (Aβ)40 were increased in senescent endothelium. Importantly, in senescent human BMECs, treatment with BACE1 inhibitor IV inhibited Aβ generation and increased sAPPα production by enhancing a disintegrin and metalloprotease (ADAM)10 expression...

BACKGROUND: The local inflammatory tissue response after acute myocardial infarction (MI) determines subsequent healing. Systemic interaction may induce neuroinflammation as a precursor to neurodegeneration. OBJECTIVES: This study sought to assess the influence of MI on cardiac and brain inflammation using noninvasive positron emission tomography (PET) of the heart-brain axis. METHODS: After coronary artery ligation or sham surgery, mice (n = 49) underwent serial whole-body PET imaging of the mitochondrial translocator protein (TSPO) as a marker of activated macrophages and microglia...

The aim of this work is to explore angiotensin I-converting enzyme (ACE) inhibitory peptides from Chlorella vulgaris (C. vulgaris) and discover the inhibitory mechanism of the peptides. After C. vulgaris proteins were gastrointestinal digested in silico, several ACE inhibitory peptides with C-terminal tryptophan were screened. Among them, two novel non-competitive ACE inhibitors, Thr-Thr-Trp (TTW) and Val-His-Trp (VHW), exhibited the highest inhibitory activity indicated by IC50 values, 0.61 ± 0.12 and 0.91 ± 0...

Introduction The metabolic syndrome includes a constellation of several well-established risk factors, which need to be aggressively treated in order to prevent overt type 2 diabetes and cardiovascular disease. While recent guidelines for the treatment of individual components of the metabolic syndrome focus on cardiovascular benefits as resulted from clinical trials, specific recent recommendations on the pharmacological management of metabolic syndrome are lacking. The objective of present paper was to review the therapeutic options for metabolic syndrome and its components, the available evidence related to their cardiovascular benefits, and to evaluate the extent to which they should influence the guidelines for clinical practice...

As a family of hormones with pleiotropic effects, natriuretic peptide (NP) system includes atrial NP (ANP), B-type NP (BNP), C-type NP (CNP), dendroaspis NP and urodilatin, with NP receptor-A (guanylate cyclase-A), NP receptor-B (guanylate cyclase-B) and NP receptor-C (clearance receptor). These peptides are genetically distinct, but structurally and functionally related for regulating circulatory homeostasis in vertebrates. In humans, ANP and BNP are encoded by NP precursor A (NPPA) and NPPB genes on chromosome 1, whereas CNP is encoded by NPPC on chromosome 2...

REVIEW
Margarita SaizSatjes, Francisco Javier Martinez-Martin
Antihypertensive treatment of patients with diabetes should include those drugs with a positive effect on metabolic parameters. Most patients with diabetes require at least two antihypertensive agents. Combining a dihydropyridine calcium channel blocker with a renin-angiotensin-aldosterone system inhibitor is a rational approach. However, not all dihydropyridines are equal with respect to their effects on metabolic parameters. Thus, manidipine exerts a positive effect on insulin resistance. However, this effect has not been observed with amlodipine...

Background: Recently we reported that angiotensin II (Ang II)-induced hypertension is mediated by group IV cytosolic phospholipase A2α (cPLA2α) via production of pro-hypertensive eicosanoids. Since Ang II increases blood pressure via its action in the subfornical organ (SFO), it led us to investigate the expression and possible contribution of cPLA2α to oxidative stress and development of hypertension in this brain area. Methods: Adenovirus (Ad)-green fluorescence protein (GFP) cPLA2α short hairpin (sh) RNA (Ad-cPLA2α shRNA) and its control Ad-scrambled shRNA (Ad-Scr shRNA) or Ad-enhanced cyan fluorescence protein cPLA2α DNA (Ad-cPLA2α DNA) and its control Ad-GFP DNA were transduced into SFO of cPLA2α+/+ and cPLA2α-/- male mice, respectively...

AIMS: Although clinical guidelines advocate the use of the highest tolerated dose of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers after acute myocardial infarction (MI), the optimal dosing or the risk-benefit profile of different doses have not been fully identified. METHODS AND RESULTS: In this multicentre trial, 495 Korean patients with acute ST segment elevation MI and subnormal left ventricular (LV) ejection fraction (<50%) were randomly allocated (2:1) to receive maximal tolerated dose of valsartan (titrated up to 320 mg/day, n = 333) or low-dose valsartan (80 mg/day, n = 162) treatment...

Use of protective angiotensin converting enzyme inhibitors (ACE-I) in patients with cardiovascular diseases (CVD) is sometimes limited by incident coughing. In clinical trials cough occurred also on placebo. We performed a meta-analysis including randomized, placebo-controlled trials reporting cough on ACE-I in patients with CVD. We evaluated the attributable fraction of cough on ACE-I accounting rate on placebo: placebo-adjusted ACE-I (%) = (ACE-I (%) - Placebo (%))/ACE-I (%). 65,054 patients from 22 included studies were analyzed...

BACKGROUND: Hyperkalaemia is a common co-morbidity in patients with heart failure with reduced ejection fraction (HFrEF). Whether it affects the use of renin-angiotensin-aldosterone system inhibitors and thereby negatively impacts outcome is unknown. Therefore, we investigated the association between potassium and uptitration of angiotensin-converting enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARB) and its association with outcome. METHODS AND RESULTS: Out of 2516 patients from the BIOSTAT-CHF study, potassium levels were available in 1666 patients with HFrEF...
