BACKGROUND The delta-5 and delta-6 desaturases, encoded by FADS1 and FADS2 genes, are key enzymes in polyunsaturated fatty acid (PUFA) metabolism that catalyze the conversion of linoleic acid (LA) into arachidonic acid (AA) and that of alpha-linolenic acid (ALA) into eicosapentaenoic acid (EPA). Single-nucleotide polymorphisms (SNPs) in FADS1 and FADS2 have(More)
In this study, we investigate the influence of three factor VII (FVII) gene polymorphisms on activated FVII levels (FVIIa), and also on the risk of myocardial infarction (MI) in patients with advanced coronary atherosclerotic disease (CAD). The -323A2 allele in the promoter is known to be associated with low FVII levels, and has been suggested to protect(More)
BACKGROUND Apolipoprotein C-III (apo C-III) is a marker of cardiovascular disease risk associated with triglyceride (TG)-rich lipoproteins. The T-455C polymorphism in the insulin-responsive element of the APOC3 gene influences TG and apo C-III concentrations. Long-chain n-3 polyunsaturated fatty acids (PUFAs) contained in fish have well-known apo(More)
BACKGROUND Increased oxidative stress is thought to play a role in the pathogenesis of the atherothrombotic process. Paraoxonases (PONs) are closely related antioxidant enzymes encoded by clustered genes on chromosome 7q. We evaluated three PON polymorphisms (PON1 Leu55Met and Gln192Arg; PON2 Ser311Cys) as possible risk factors for coronary atherosclerotic(More)
BACKGROUND Lower activity of 11 beta-hydroxysteroid dehydrogenase 2 (11beta-HSD2) classically induces hypertension by leading to an altered tetrahydrocortisol- versus tetrahydrocortisone-metabolites (THFs/THE) shuttle. Recent cell culture and animal studies suggest a role for promoter methylation, a major epigenetic feature of DNA, in regulation of HSD11B2(More)
BACKGROUND Exosomes are cytoplasm containing vesicles released by many cells that can be found in several biological fluids including urine. Urinary exosomes are released from every segment of the nephron, are detectable in urine, constitutively contain RNA (small RNAs and mRNAs) and harbor unique subset of proteins, reflecting their cellular source.

1 T he metabolic syndrome, clinically defined by the Adult Treatment Panel III (ATPIII) (1), affects ϳ25% of western adults (2). The metabolic syndrome is closely linked to insulin resist a n c e a n d i m p l i e s a n i n c r e a s e d cardiovascular risk (3,4). Accumulating evidence suggests a link between body iron excess and insulin metabolism (5).(More)
BACKGROUND Low concentrations of pyridoxal-5'-phosphate (PLP), the active metabolite of vitamin B-6, are associated with high C-reactive protein (CRP) concentrations. Both low PLP and elevated inflammatory markers, such as high-sensitivity CRP (hs-CRP) and fibrinogen, are related to higher risk of coronary artery disease (CAD). OBJECTIVES The objectives(More)
Apolipoprotein C-III (apoC-III) is a marker of triglyceride (TG)-rich lipoproteins, which are often increased in metabolic syndrome (MS). The T-455C polymorphism in the insulin-responsive element of the APOC3 gene influences TG and apoC-III levels. To evaluate the contribution of apoC-III levels and T-455C polymorphisms in the coronary artery disease (CAD)(More)
BACKGROUND G20210A prothrombin mutation has been associated with high prothrombin levels and an increased risk of venous thrombosis. The role of this common polymorphism, as well as that of prothrombin levels, in determining the risk of arterial disease is still somewhat controversial. METHODS AND RESULTS We determined the prevalence of the G20210A(More)
