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 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)
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 Relative little attention has been devoted until now to the combined effects of gene polymorphisms of the hemostatic pathway as risk factors for Myocardial Infarction (MI), the main thrombotic complication of Coronary Artery Disease (CAD). The aim of this study was to evaluate the combined effect of ten common prothrombotic polymorphisms as a(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 Plasma factor VII concentrations (FVIIa), a marker of coronary artery disease (CAD) risk, are influenced by genetic markers at the promoter site: the A2 allele, due to a 10bp insertion at position -323, is a determinant of lower FVIIa concentrations and reduced CAD risk, while the -402A allele, due to a G>A substitution, confers increased(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.

OBJECTIVE Molecular variants of the angiotensinogen (AGT) and the angiotensin II type 1 receptor (ATR) genes have been associated with the risk of coronary artery disease (CAD) and myocardial infarction (MI), but data so far available are conflicting. The primary object of the paper is to verify this possible association by a rigorous, angiographically(More)
