Factor VII Activating Protease Expression in Human Platelets and Accumulation in Symptomatic Carotid Plaque.

Background Factor VII activating protease (FSAP) is of interest as a marker for vascular inflammation and plaque destabilization. The aim of this study was to analyze the expression profile of FSAP in endarterectomy specimens that were taken from patients with asymptomatic and symptomatic carotid atherosclerotic plaques and to compare them with circulating FSAP levels. Methods and Results Plasma FSAP concentration, activity, and mRNA expression were measured in endarterectomy specimens and in monocytes and platelets.

Expression of the Marburg I Single Nucleotide Polymorphism (MI-SNP) and the Marburg II Single Nucleotide Polymorphism (MII-SNP) of the Factor VII-Activating Protease (FSAP) Gene and Risk of Coronary Artery Disease (CAD): A Pilot Study in a Single Population.

BACKGROUND Factor VII-activating protease (FSAP) has a role in vascular inflammation and may have a role coronary artery disease (CAD). The aim of this study was to investigate the association between two naturally occurring single nucleotide polymorphisms (SNPs) in the FSAP gene and the risk of coronary artery disease (CAD). MATERIAL AND METHODS Of 733 patients, 173 patients had symptoms of angina, and 560 patients had CAD confirmed by coronary angiography.

MicroRNA expression profile of human advanced coronary atherosclerotic plaques.

MicroRNA (miR) is reported to be involved in vascular inflammation and may represent a novel class of diagnostic biomarkers in cardiovascular disease. We aimed to identify the miR expression profile in human advanced coronary atherosclerotic plaques (CAP) and to connect this expression to the processes in atherosclerosis. Microarray techniques and TaqMan polymerase chain reaction were used to analyse the global expression of 352 miRs in CAP obtained during ACS MULTI-LINK study.

Identification of microRNAs as potential cellular monocytic biomarkers in the early phase of myocardial infarction: a pilot study.

MicroRNA has been increasingly suggested to be involved in vascular inflammation. The aim of this study was to assess the expression profile of miRs as possible novel cellular biomarkers in circulating monocytes in patients with ST-segment elevation myocardial infarction (STEMI). Microarray techniques and TaqMan polymerase chain reaction were used to analyse the global expression of 352 miRNAs in peripheral blood monocytes from healthy donors (n = 20) and patients (n = 24) with acute STEMI.

Differential Expression of MicroRNAs in Endarterectomy Specimens Taken from Patients with Asymptomatic and Symptomatic Carotid Plaques.

Objective: Stroke and transient ischemic attacks are considered as clinical manifestations of atherosclerotic disease due to on-going vascular inflammation and finally atherothrombosis of the carotid arteries. MicroRNAs (miRNA/miR) are known to be involved in vascular inflammation and plaque destabilization. The aim of this study was to analyze the expression profile of selected miRNAs in endarterectomy specimen from carotid arteries that were taken from patients with asymptomatic and symptomatic atherosclerotic plaques.

Monocyte CD40 expression in young healthy female smokers and/or oral contraceptives users without additional risk factors for atherosclerosis.

Objective: Atherosclerosis, as an inflammatory disease, is characterized by pathologically altered levels of cytokines. We investigated whether smoking and/or oral contraceptives (OCs) affect the CD40/CD40L plasma levels and expression in young females without other risk factors for atherosclerosis.

Patients And Methods: A case-control single-center design was used.

Regulation of monocyte/macrophage function by factor VII activating protease (FSAP).

Objective: Factor VII activating protease (FSAP) is a novel regulator of vascular inflammation and hemostasis. However, the molecular mechanism by which circulating FSAP influences inflammatory events and progression of atherosclerosis is not yet entirely understood. Here we have investigated the influence of FSAP on monocyte/macrophage functions.

Association of circulating factor seven activating protease (FSAP) and of oral Omega-3 fatty acids supplements with clinical outcome in patients with atrial fibrillation: the OMEGA-AF study.

Factor VII Activating Protease (FSAP) activates factor VII (FVII) as well as pro-urokinase (uPA). Our goal was to evaluate the relation between plasma levels of FSAP and clinical instability in atrial fibrillation (AF) and possible effects of oral omega-3 fatty acids (FA) supplements. 101 patients with persistent AF were analyzed in the OMEGA-AF Study.

Factor seven activating protease (FSAP) expression in human placenta and its role in trophoblast migration.

Objectives: Factor seven activating protease (FSAP) is a plasma serine protease known to play a critical role in hemostasis and remodeling processes: FSAP levels increase markedly during normal pregnancy. In order to define the role of FSAP in vascular pathophysiology in pregnant women and particularly in the placenta, we performed this study (i) to evaluate the FSAP expression in human placenta and (ii) to identify the role of FSAP in human trophoblast migration.

Study Design: FSAP expression in placental tissues was analyzed by using immunohistochemistry and reverse transcriptase-polymerase chain reaction (RT-PCR).

Nicotine modulation of factor VII activating protease (FSAP) expression in human monocytes.

Aim: Factor VII activating protease (FSAP) is a plasma serine protease involved in hemostasis and remodeling processes. Increased levels of circulating FSAP during pregnancy and in women using oral contraceptives (OCs) indicate that the hormonal status critically influences FSAP expression. In this respect, the aim of this study was to quantify nicotine modulation of FSAP expression in human monocytes/macrophages isolated from healthy female smokers and non-smokers, and from women who use OCs and smoke.

Circulating factor VII activating protease (FSAP) is associated with clinical outcome in acute coronary syndrome.

Background: Factor VII activating protease (FSAP) is a circulating serine protease strongly expressed in unstable plaques and may serve as a marker of plaque destabilization. The aim of this study was to examine the relation between plasma concentrations of FSAP and clinical instability and outcome in coronary artery disease (CAD).

Methods And Results: Circulating FSAP concentration and activity, as well as FSAP mRNA expression in monocytes, were measured in 231 sequential patients who underwent coronary angiography because of stable angina pectoris (n=50), unstable angina pectoris (n=43), or acute myocardial infarction (n=87).

Factor seven ativating potease (FSAP) levels during normal pregnancy and in women using oral contraceptives.

Introduction: Factor seven activating protease (FSAP) is a plasma serine protease involved in haemostasis and remodeling processes. We have investigated whether pregnancy or the use of oral contraceptives (OCs) influences circulating FSAP levels. The effect of female sex hormones on FSAP expression in cultured cells was also determined.

Factor Seven Activating Protease (FSAP) expression in human monocytes and accumulation in unstable coronary atherosclerotic plaques.

Objective: The Factor Seven Activating Protease (FSAP) is known to influence fibrinolysis and to play a critical role in the inhibition of vascular smooth muscle cell (VSMC) proliferation and migration as well as neointima formation. In order to define the role of FSAP in vascular pathophysiology we have investigated the expression of FSAP protein and mRNA in human vascular cells and coronary atherosclerotic plaques with defined clinical features.

Methods And Results: Directional coronary atherectomy (DCA) specimens from 40 lesions were analyzed for FSAP antigen and mRNA expression.

Statins prevent NF-kappaB transactivation independently of the IKK-pathway in human endothelial cells.

Statins have been linked to a wide range of vascular benefits, many of them are likely to be due to attenuation of chronic vascular inflammation. Nuclear factor kappaB (NF-kappaB) is one of the key regulators of transcription of a variety of genes involved in immune and inflammatory responses. Therefore, we investigated the effect of statins on TNF-alpha-induced NF-kappaB signaling in human endothelial cells (EC).
