Negative Regulation of Human Fibrinogen Gene Expression by Peroxisome Proliferator-activated Receptor alpha Agonists via Inhibition of CCAAT Box/Enhancer-binding Protein beta

Fibrinogen is a coagulation factor and an acute phase reactant up-regulated by inflammatory cytokines, such as interleukin 6 (IL-6). Elevated plasma fibrinogen levels are associated with coronary heart diseases. Fibrates are clinically used hypolipidemic drugs that act via the nuclear receptor peroxisome proliferator-activated receptor alpha ...

Relationship between visceral fat and PAI-1 in overweight men and women before and after weight loss

This study was aimed at evaluating the relationship between visceral fat accumulation and plasma plasminogen activator inhibitor-1 (PAI-1) levels in healthy, obese men and women undergoing weight loss therapy. The subjects, 25 men and 25 premenopausal women, aged between 26 and 49 years, with an initial body mass index between 28 and 38 kg/m2,...

Atherosclerosis in APOE(*)3-Leiden transgenic mice from proliferative to atheromatous stage

Background - This study documents (1) the progression of atherosclerosis along the entire arterial tree in APOE(*)3-Leiden mice after 1, 4, 6, 9, and 12 months of a high-fat/high-cholesterol (HFC) diet and (2) the amount and phenotype of DNA-synthesizing and apoptotic cells in different lesion types after 6 months of HFC diet. Methods and...

Fibrates suppress fibrinogen gene expression in rodents via activation of the peroxisome proliferator-activated receptor-α

Plasma fibrinogen levels have been identified as an important risk factor for cardiovascular diseases. Among the few compounds known to lower circulating fibrinogen levels in humans are certain fibrates. We have studied the regulation of fibrinogen gene expression by fibrates in rodents. Treatment of adult male rats with fenofibrate (0.5% [wt/wt...

Regulatory aspects of fibrinogen and plasminogen activator inhibitor-1 gene regulation: role of the peroxisome proliferator-activated receptor

Fibrate-modulated expression of fibrinogen, plasminogen activator inhibitor-1 and apolipoprotein A-I in cultured cynomolgus monkey hepatocytes. Role of the peroxisome proliferator-activated receptor-α

Fibrates are used to lower plasma triglycerides and cholesterol levels in hyperlipidemic patients. In addition, fibrates have been found to alter the plasma concentrations of fibrinogen, plasminogen activator inhibitor-1 (PAI-1) and apolipoprotein A-I (apo A-I). We have investigated the in vitro effects of fibrates on fibrinogen, PAI-1 and apo A...

Role of the peroxisome proliferator-activated receptor-a in the down regulation of fibrinogen gene expression in rodents

Effects of gemfibrozil and ciprofibrate on plasma levels of tissue-type plasminogen activator, plasminogen activator inhibitor-1 and fibrinogen in hyperlipidaemic patients

Evaluation of fibrate treatment in humans has focused primarily on its anti-lipidaemic effects. A potentially favourable haemostasis-modulating activity of fibrates has also been recognized but the data are not consistent. We sought to learn more about this variability by examining the effects of gemfibrozil and ciprofibrate on plasma levels of...

Studies on the role of PPAR in the fibrate-modulated gene expression of apolipoprotein A-I, plasminogen activator inhibitor 1, and fibrinogen in primary hepatocyte cultures from cynomolgus monkey
