BACKGROUND Atrial natriuretic peptide (ANP) has antihypertrophic and antifibrotic properties that are relevant to AF substrates. The -G664C and rs5065 ANP single nucleotide polymorphisms (SNP) have been described in association with clinical phenotypes, including hypertension and left ventricular hypertrophy. A recent study assessed the association of early(More)
The stroke-prone spontaneously hypertensive rat (SHRsp) represents an animal model of increased susceptibility to high-salt diet-induced cerebral and renal vascular injuries. High blood pressure and genetic factors are viewed as major contributing factors. In high-salt-loaded SHRsp and stroke-resistant SHR animals, we determined blood pressure levels,(More)
BACKGROUND Abnormalities of vascular smooth muscle cells (VSMCs) contribute to development of vascular disease. Atrial natriuretic peptide (ANP) exerts important effects on VSMCs. A common ANP molecular variant (T2238C/αANP) has recently emerged as a novel vascular risk factor. OBJECTIVES We aimed at identifying effects of CC2238/αANP on viability,(More)
RATIONALE C2238 atrial natriuretic peptide (ANP) minor allele (substitution of thymidine with cytosine in position 2238) associates with increased risk of cardiovascular events. OBJECTIVE We investigated the mechanisms underlying the vascular effects of C2238-αANP. METHODS AND RESULTS In vitro, human umbilical vein endothelial cell were exposed to(More)
Subjects carrying the T2238C ANP gene variant have a higher risk to suffer a stroke or myocardial infarction. The mechanisms through which T2238C/αANP exerts detrimental vascular effects need to be fully clarified. In the present work we aimed at exploring the impact of C2238/αANP (mutant form) on atherosclerosis-related pathways. As a first step, an(More)
BACKGROUND NPR3, located on human chromosome 5 (5p14-p13), encodes the natriuretic peptide receptor type C (NPR-C) that is mainly known as the natriuretic peptide clearance receptor. Involvement of NPR3 in susceptibility to cardiovascular diseases, i.e. hypertension, has been previously shown. With regard to stroke predisposition, evidence for a potential(More)
OBJECTIVES The aim of this study was to investigate the impact of rs5065 atrial natriuretic peptide (ANP) gene variant on coronary artery disease (CAD) and its outcomes and to gain potential mechanistic insights on the association with CAD. BACKGROUND Either modified ANP plasma levels or peptide structural alterations have been involved in development of(More)
A vaccination cycle cannot always be completed with the same type of vaccine with which it was initiated because the same type of vaccine is not always available at the vaccination centers. For this reason we have verified the possibility of substituting one of two anti hepatitis B DNA-recombinant vaccines [Engerix B (SK&F); Recombivax HB (MSD)] both(More)
