Oxidative stress (OS) plays an important role in atherogenesis and since glutathione S-transferases (GSTs) provide protection against OS, we have tested the hypothesis that deletion polymorphisms in two GSTs (GSTM1 and GSTT1) may affect the risk of developing atherosclerosis. A total of 382 individuals (200 patients with atherosclerosis and 182 healthy controls) were included in this association study. Genomic DNA was isolated from peripheral blood cells or from buccal epithelial cells and genotyping was performed using multiplex-PCR or real-time PCR methods...

Thromboxane A synthase 1 (TBXAS1) catalyses the synthesis of thromboxane A2 (TXA2), which plays an important role in the pathogenesis of ischemic stroke. Thus, the TBXAS1 gene was investigated as a candidate gene involved in the formation of atherosclerosis. This case-control study collected peripheral blood specimens and clinical data of 370 ischemic stroke patients and 340 healthy controls in the Northern Chinese Han population from October 2010 to May 2011. Two TBXAS1 single-nucleotide polymorphisms, rs2267682 and rs10487667, were analyzed using a SNaPshot Multiplex sequencing assay to explore the relationships between the single-nucleotide polymorphisms in TBXAS1 and ischemic stroke...

Cardiovascular diseases (CVDs) remain the leading cause of death worldwide, while coronary artery disease (CAD) account for a large part of CVDs. Vascular CXCR4 could limit atherosclerosis by maintaining arterial integrity. Here, we conducted a population-based, case-control study to evaluate the associations of common genetic variation within the CXCR4 gene (rs2228014, rs117600832, rs2471859, and rs2322864) with CAD risk in a Chinese population. We found that CXCR4 rs2228014 was significantly associated with 1...

We evaluated whether CETP and LCAT gene polymorphisms are statistically associated with the high-density lipoprotein (HDL) size distribution, the cholesterol level of HDL subclasses, and the acute coronary syndrome (ACS) susceptibility. Two CETP gene polymorphisms (rs4783961 and rs708272) and one LCAT polymorphism (rs2292318) were genotyped by 5' exonuclease TaqMan assays in 619 patients with ACS and 607 control individuals. For HDL analysis, a subgroup of 100 healthy individuals was recruited; the HDL subclasses were separated via ultracentrifugation and polyacrylamide gradient gel electrophoresis under native conditions...

Objective Vitamin D deficiency is known as an important risk factor in pathogenesis of atherosclerosis, which contributes to stroke development. Genetic variations including single nucleotide polymorphisms (SNPs) in enzymes involved in vitamin D metabolism can affect susceptibility to the development of stroke. Therefore, the objective of this study was to investigate the association between polymorphisms of vitamin D metabolizing enzymes (rs927650 SNP in CYP24A1, and rs10741657 SNP in CYP2R1 genes,) and ischemic stroke risk in Turkish population...

Carotid Intima-media thickness (CIMT) and plaque are well established markers of subclinical atherosclerosis and are widely used for identifying subclinical atherosclerotic disease. We performed association analyses using Metabochip array to identify genetic variants that influence variation in CIMT and plaque, measured using B-mode ultrasonography, in rheumatoid arthritis (RA) patients. Data on genetic associations of common variants associated with both CIMT and plaque in RA subjects involving Mexican Americans (MA) and European Americans (EA) populations are presented in this article...

LPP3 is an integral membrane protein belonging to a family of enzymes (LPPs) that display broad substrate specificity and catalyse dephosphorylation of several lipid substrates, including lysophosphatidic acid and sphingosine-1-phosphate. In mammals, the LPP family consists of three enzymes named LPP1, LPP2 and LPP3, which are encoded by three independent genes, PLPP1, PLPP2 and PLPP3, respectively (formerly known as PPAP2A, PPAP2C, PPAP2B). These three enzymes, in vitro, do not seem to differ for catalytic activities and substrate preferences...

Atherosclerosis is a chronic, progressive, and multifactorial disease modulated by genetic and environmental factors. In recent years, the paradigm that explained atherosclerosis as resulting from a complex interaction between factors not accessible to medical intervention, and modifiable risk factors has changed. In this paradigm, alterations in lipid metabolism were the pivotal concept of atherosclerosis as a chronic degenerative disease. In the last years, an increasing number of observations have shown that the innate and adaptive immune responses to lipoprotein deposition and oxidation in the arterial wall significantly influence atherosclerosis...

Atherosclerosis and its cardiovascular complications are the main cause of death in diabetic patients. Patients with diabetes mellitus have a greater than 10-fold risk of cardiovascular disease in their lifetime. The carotid intima-media thickness (cIMT), a surrogate marker for the presence and progression of atherosclerosis, predicts future cardiovascular events in asymptomatic subjects with type 2 diabetes mellitus (T2DM). This review focuses on genetic variants that contribute to the pathobiology of subclinical atherosclerosis in the setting of T2DM...

Several studies suggest an important role of Acyl-CoA: cholesterol acyltransferase-1(ACAT-1) in the development of atherosclerosis. The aim of present study was to investigate whether there exists a possible correlation between genetic variations in ACAT-1 genes and coronary artery disease (CAD) risk. Four polymorphisms (rs1044925, rs11545566, rs12121758 and rs10913733) were finally selected and genotyped in 750 CAD patients and 580 health controls, using the improved multiplex ligation detection reaction (iMLDR) method...

BACKGROUND: The SstI polymorphism in the apolipoprotein 3 gene (apoC3) has been identified in many ethnic groups. In addition, the S2 allele of the SstI polymorphism is shown to be associated with increased plasma triglyceride (TG) levels. Plasma apoCIII is an important atherogenic factor, which interrupts lipid metabolism and is positively associated with plasma TG levels. However, the existence of the SstI polymorphism in the Li ethnic group in China remains to be confirmed. The relationship between the S2 allele of the SstI polymorphism and plasma apoCIII or TG and their roles in atherosclerosis are also unknown...

The burden of atherosclerosis is heritable and associated with elevated risk of developing CVDs. Here, we evaluated genetic variants of adiponectin (ADIPOQ) gene, which has important role in anti- atherosclerosis, with risk of atherosclerosis among a large Chinese population. Our results show that rs74577862 was significantly associated with risk of atherosclerosis (OR=2.08; 95%CI=1.48-2.91; P=2.2×10-5 ). When stratified by atherosclerosis site, rs74577862 was associated with increased risk of both carotid atherosclerosis (OR=2...

The internal thoracic artery (ITA) that differs from coronary artery (CA), rarely develops atherosclerosis. Understanding the mechanism underlying such a difference will help to pave a new way to the prevention and treatment of the disease. We hypothesize herein that the difference in susceptibility to atherosclerosis between CA and ITA is attributable to the heterogeneity of perivascular adipose tissues (PVATs) surrounding these two kinds of arteries, i.e. PVAT-CA and PVAT-ITA. We isolated PVAT from eight patients of coronary heart disease (CHD) and four non-CHD patients...

Over the past few years, an increasing number of studies have identified rare variants that contribute to trait heritability. Due to the extreme rarity of some individual variants, gene-based association tests have been proposed to aggregate the genetic variants within a gene, pathway, or specific genomic region as opposed to a one-at-a-time single variant analysis. In addition, in longitudinal studies, statistical power to detect disease susceptibility rare variants can be improved through jointly testing repeatedly measured outcomes, which better describes the temporal development of the trait of interest...

Ischemic stroke (IS), the leading neurology cause of death and disability worldwide, is influenced by gene polymorphisms. To explore the association between IS and Apolipoprotein E ( APOE ) gene polymorphisms, a case-control study containing 513 IS patients and 514 controls without IS was conducted in a Northwest China Han population. MassARRAY iPLEX system was applied to determine the APOE polymorphisms according to the alleles of two single nucleotide polymorphisms (SNPs) of APOE , rs429358, and rs7412. The results showed that rs429358 and rs7412 were in Hardy-Weinberg equilibrium (HWE) in both cases and controls groups...

Cardiovascular dysfunction and heart failure associated with aging not only impairs the cardiac function but also the quality of life eventually decreasing the life expectancy of the elderly. Notably, cardiac tissue can prematurely age under certain conditions such as genetic mutation, persistent redox stress and overload, aberrant molecular signaling, DNA damage, telomere attrition, and other pathological insults. While cardiovascular-related morbidity and mortality is on the rise and remains a global health threat, there has been only little to moderate improvements in its medical management...
