    ABSTRACT: Identification and treatment of abdominal aortic aneurysm (AAA) remain among the most prominent challenges in vascular medicine. MicroRNAs (miRNAs) are crucial regulators of cardiovascular pathology and represent intriguing targets to limit AAA expansion. Here we show, by using two established murine models of AAA disease along with human aortic tissue and plasma analysis, that miR-24 is a key regulator of vascular inflammation and AAA pathology. In vivo and in vitro studies reveal chitinase 3-like 1 (Chi3l1) to be a major target and effector under the control of miR-24, regulating cytokine synthesis in macrophages as well as their survival, promoting aortic smooth muscle cell migration and cytokine production, and stimulating adhesion molecule expression in vascular endothelial cells. We further show that modulation of miR-24 alters AAA progression in animal models, and that miR-24 and CHI3L1 represent novel plasma biomarkers of AAA disease progression in humans.

    ABSTRACT: Exploiting genotyping, DNA sequencing, imputation, and trans-ancestral mapping, we used Bayesian and frequentist approaches to model the IRF5-TNPO3 locus association, now implicated in two immunotherapies and seven autoimmune diseases. Specifically, in systemic lupus erythematosus (SLE) we resolved separate associations in the IRF5 promoter (all ancestries) and with an extended European haplotype. We captured 3,230 IRF5-TNPO3 high quality, common variants across five ethnicities in 8,395 SLE cases and 7,367 controls. The genetic effect from the IRF5 promoter can be explained by any one of four variants in 5.7 kb (p-valuemeta=6x10(-49); OR=1.38-1.97). The second genetic effect spanned an 85.5 kb, 24 variant haplotype that included the genes IRF5 and TNPO3 (p-valuesEU=10(-27)-10(-32), OR=1.7-1.81). Many variants at the IRF5 locus with previously assigned biological function are not members of either final credible set of potential causal variants identified herein. In addition to the known biologically functional variants, we demonstrated that the risk allele of rs4728142, a variant in the promoter among the lowest frequentist probability and highest Bayesian posterior probability, was correlated with IRF5 expression and differentially binds the transcription factor ZBTB3. Our analytical strategy provides a novel framework for future studies aimed at dissecting etiological genetic effects. Finally, both SLE elements of the statistical model appear to operate in Sjögren's syndrome and systemic sclerosis while only the IRF5-TNPO3 gene-spanning haplotype is associated in primary biliary cirrhosis, demonstrating the nuance of similarity and difference in autoimmune disease risk mechanisms at IRF5-TNPO3.

    ABSTRACT: Differences in clinical presentation between patients with tricuspid aortic valves (TAVs) or bicuspid aortic valves (BAVs) and aortic valve disease are evident. Whether these differences can be attributed to differences in cardiovascular risks remains uncertain.

    ABSTRACT: Objective To use the rs1229984 variant in the alcohol dehydrogenase 1B gene (ADH1B) as an instrument to investigate the causal role of alcohol in cardiovascular disease. Design Mendelian randomisation meta-analysis of 56 epidemiological studies. Participants 261 991 individuals of European descent, including 20 259 coronary heart disease cases and 10 164 stroke events. Data were available on ADH1B rs1229984 variant, alcohol phenotypes, and cardiovascular biomarkers. Main outcome measures Odds ratio for coronary heart disease and stroke associated with the ADH1B variant in all individuals and by categories of alcohol consumption. Results Carriers of the A-allele of ADH1B rs1229984 consumed 17.2% fewer units of alcohol per week (95% confidence interval 15.6% to 18.9%), had a lower prevalence of binge drinking (odds ratio 0.78 (95% CI 0.73 to 0.84)), and had higher abstention (odds ratio 1.27 (1.21 to 1.34)) than non-carriers. Rs1229984 A-allele carriers had lower systolic blood pressure (−0.88 (−1.19 to −0.56) mm Hg), interleukin-6 levels (−5.2% (−7.8 to −2.4%)), waist circumference (−0.3 (−0.6 to −0.1) cm), and body mass index (−0.17 (−0.24 to −0.10) kg/m2). Rs1229984 A-allele carriers had lower odds of coronary heart disease (odds ratio 0.90 (0.84 to 0.96)). The protective association of the ADH1B rs1229984 A-allele variant remained the same across all categories of alcohol consumption (P=0.83 for heterogeneity). Although no association of rs1229984 was identified with the combined subtypes of stroke, carriers of the A-allele had lower odds of ischaemic stroke (odds ratio 0.83 (0.72 to 0.95)). Conclusions Individuals with a genetic variant associated with non-drinking and lower alcohol consumption had a more favourable cardiovascular profile and a reduced risk of coronary heart disease than those without the genetic variant. This suggests that reduction of alcohol consumption, even for light to moderate drinkers, is beneficial for cardiovascular health.

    ABSTRACT: Atherosclerosis is an inflammatory disease associated with the activation of complex innate immune Toll-like receptors and cytoplasmic nucleotide-binding oligomerization domain-containing protein (NOD)-like receptor (NLR) pathways. However, the function of most innate immune receptors in atherosclerosis remains unclear. Here we show that NOD2 is a crucial innate immune receptor influencing vascular inflammation and atherosclerosis severity. A 10-week stimulation with muramyl dipeptide (MDP), the NOD2 cognate ligand, showed aggravated atherosclerosis, as indicated by the augmented lesion burden, increased vascular inflammation and enlarged lipid-rich necrotic cores in Ldlr−/− mice. Myeloid-specific ablation of NOD2, but not its downstream kinase receptor-interacting serine/threonine-protein kinase 2, restrained the expansion of the lipid-rich necrotic core in Ldlr−/− chimeric mice. In vitro stimulation of macrophages with MDP enhanced the uptake of oxidized LDL and impaired cholesterol efflux in concordance with upregulation of scavenger receptor A1/2 and downregulation of ATP-binding cassette transporter A1. Ex vivo stimulation of human carotid plaques with MDP led to increased activation of inflammatory signaling pathways, and p38 MAPK and NF-κB-mediated release of pro-inflammatory cytokines. Altogether, this study suggests that NOD2 contributes to the expansion of the lipid-rich necrotic core and promotes vascular inflammation in hyperlipidemic mice.This article is protected by copyright.

    ABSTRACT: Genome-wide association studies have identified a locus on chromosome 19 associated with plasma triglyceride (TG) concentration and nonalcoholic fatty liver disease. However, the identity and functional role of the gene(s) responsible for these associations remain unknown. Of 19 expressed genes contained in this locus, none has previously been implicated in lipid metabolism. We performed gene expression studies and expression quantitative trait locus analysis in 206 human liver samples to identify the putative causal gene. Transmembrane 6 superfamily member 2 (TM6SF2), a gene with hitherto unknown function, expressed predominantly in liver and intestine, was identified as the putative causal gene. TM6SF2 encodes a protein of 351 amino acids with 7-10 predicted transmembrane domains. Otherwise, no other protein features were identified which could help to elucidate the function of TM6SF2. Protein subcellular localization studies with confocal microscopy demonstrated that TM6SF2 is localized in the endoplasmic reticulum and the ER-Golgi intermediate compartment of human liver cells. Functional studies for secretion of TG-rich lipoproteins (TRLs) and lipid droplet content were performed in human hepatoma Huh7 and HepG2 cells using confocal microscopy and siRNA inhibition and overexpression techniques. In agreement with the genome-wide association data, it was found that TM6SF2 siRNA inhibition was associated with reduced secretion of TRLs and increased cellular TG concentration and lipid droplet content, whereas TM6SF2 overexpression reduced liver cell steatosis. We conclude that TM6SF2 is a regulator of liver fat metabolism with opposing effects on the secretion of TRLs and hepatic lipid droplet content.

    ABSTRACT: The prevalence for thoracic aortic aneurysms (TAAs) is significantly increased in patients with a bicuspid aortic valve (BAV) compared with patients who have a normal tricuspid aortic valve (TAV). TAA rupture is a life-threatening event, and biomechanics-based simulations of the aorta may help to disentangle the molecular mechanism behind its development and progression. The present study used polarized microscopy and macroscopic in vitro tensile testing to explore collagen organization and mechanical properties of TAA wall specimens from BAV and TAV patients.

    ABSTRACT: IntroductionAortic valve calcification (AVC) may predict poor outcome. Bicuspid aortic valve (BAV) leads to several haemodynamic changes accelerating the progress of aortic valve (AV) disease.AimsTo compare the diagnostic accuracy of transoesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) in the assessment of aortic valve phenotype and degree of AVC, with intra-operative evaluation as a reference.Methods We examined 169 patients (median age 65 years, 51 women) without significant coronary artery disease undergoing AV and/or aortic root surgery. TTE was performed within a week prior to surgery and TEE at the time of surgery.ResultsCompared with surgical AVC assessment, visual evaluation using a 5-grade scoring system and real-time images showed a higher correlation (TTE r = 0·83 and TEE r = 0·82) than visual (TTE r = 0·64 and TEE 0·63) or grey scale mean (GSMn) (TTE r = 0·63 and TEE r = 0·52) assessment of end-diastolic still frames. AVC assessment using real-time images showed high intraclass correlation coefficients (TTE 0·94 and TEE 0·93). With regard to BAV, TEE was superior to TTE with a higher interobserver agreement, sensitivity and specificity (0·86, 92% and 94% versus 0·57, 77% and 82%, respectively).Conclusion Semi-quantitative AVC assessment of real-time cine loops from both TEE and TTE correlated well with intra-operative evaluation of AVC. Applying a predefined scoring system for AVC evaluation assures a high interobserver correlation. TEE was superior to TTE for evaluation of valve phenotype and should be considered when a diagnosis of BAV is clinically important.

    ABSTRACT: The findings of studies investigating whether or not low serum 25-hydroxyvitamin D [25(OH)D] concentration promotes development of atherosclerosis have been contradictory. The present study employed a Mendelian randomisation approach and carotid artery intima-media thickness (cIMT), a surrogate marker of coronary artery disease, to address this question. The multicentre, longitudinal Carotid Intima-Media Thickness and IMT-Progression as Predictors of Vascular Events in a High-Risk European Population (IMPROVE) cohort study, which enrolled individuals with at least three cardiovascular risk factors and no history or symptoms of cardiovascular disease, was used for the present investigation. Participants underwent carotid ultrasound examination at baseline and at months 15 and 30. Six single nucleotide polymorphisms (SNPs) associated with serum 25(OH)D concentration in genome-wide association studies were identified and genotyped in 3,418 individuals, of whom 929 had type 2 diabetes. SNPs in the genes encoding vitamin D binding protein (GC; rs2282679 and rs7041) and 7-dehydrocholesterol reductase/NAD synthetase-1 (DHCR7; rs12785878 and rs3829251) were negatively associated with 25(OH)D levels. Effect sizes and significance of associations between SNPs and 25(OH)D levels differed between individuals with and without type 2 diabetes, although no significant interactions were observed. A SNP in DHCR7 interacted with type 2 diabetes to significantly influence progression of cIMT measures independent of 25(OH)D levels and established risk factors. Expression analysis demonstrated that this SNP modulates DHCR7 mRNA levels in aortic adventitia. SNPs in GC and DHCR7 were associated with serum levels of 25(OH)D, but only rs3829251 (DHCR7) influenced progression of subclinical atherosclerosis, as measured by cIMT, in a manner dependent on type 2 diabetes status but independent of 25(OH)D levels.

    ABSTRACT: Tissue plasminogen activator (tPA), a serine protease, catalyzes the conversion of plasminogen to plasmin, the major enzyme responsible for endogenous fibrinolysis. In some populations, elevated plasma levels of tPA have been associated with myocardial infarction and other cardiovascular diseases. We conducted a meta-analysis of genome-wide association studies to identify novel correlates of circulating levels of tPA. Fourteen cohort studies with tPA measures (N=26 929) contributed to the meta-analysis. Three loci were significantly associated with circulating tPA levels (P<5.0×10(-8)). The first locus is on 6q24.3, with the lead single nucleotide polymorphism (SNP; rs9399599; P=2.9×10(-14)) within STXBP5. The second locus is on 8p11.21. The lead SNP (rs3136739; P=1.3×10(-9)) is intronic to POLB and <200 kb away from the tPA encoding the gene PLAT. We identified a nonsynonymous SNP (rs2020921) in modest linkage disequilibrium with rs3136739 (r(2)=0.50) within exon 5 of PLAT (P=2.0×10(-8)). The third locus is on 12q24.33, with the lead SNP (rs7301826; P=1.0×10(-9)) within intron 7 of STX2. We further found evidence for the association of lead SNPs in STXBP5 and STX2 with expression levels of the respective transcripts. In in vitro cell studies, silencing STXBP5 decreased the release of tPA from vascular endothelial cells, whereas silencing STX2 increased the tPA release. Through an in silico lookup, we found no associations of the 3 lead SNPs with coronary artery disease or stroke. We identified 3 loci associated with circulating tPA levels, the PLAT region, STXBP5, and STX2. Our functional studies implicate a novel role for STXBP5 and STX2 in regulating tPA release.

    ABSTRACT: -Secretory phospholipase A2 (sPLA2) enzymes are considered to play a role in atherosclerosis. sPLA2 activity encompasses several sPLA2 isoenzymes, including sPLA2-V. While observational studies show strong association between elevated sPLA2 activity and CHD, no assay to measure sPLA2-V levels exists and the only evidence linking the sPLA2-V isoform to atherosclerosis progression comes from animal studies. In the absence of an assay that directly quantifies sPLA2-V levels, we used PLA2G5 mRNA levels in a novel, modified Mendelian randomization approach to investigate the hypothesized causal role of sPLA2-V in coronary heart disease (CHD) pathogenesis. -Using data from the Advanced Study of Aortic Pathology, we identified the single nucleotide polymorphism (SNP) in PLA2G5 showing strongest association with PLA2G5 mRNA expression levels, as a proxy for sPLA2-V levels. We tested the association of this SNP with sPLA2 activity and CHD events in four prospective and 14 case-control studies with 27,230 events and 70,500 controls. rs525380C>A showed the strongest association with PLA2G5 mRNA expression (P=5.1x10(-6)). There was no association of rs525380C>A with plasma sPLA2 activity (difference in geometric mean of sPLA2 activity per rs525380 A-allele 0.4% (95%CI: -0.9%, 1.6%), P=0.56). In meta-analyses, the odds ratio for CHD per A allele was 1.02 (95% CI: 0.99, 1.04; P=0.20). -This novel approach for SNP selection for this modified Mendelian randomization analysis showed no association between rs525380 (the lead SNP for PLA2G5 expression, a surrogate for sPLA2-V levels) and CHD events. The evidence does not support a causal role for sPLA2-V in CHD.

    ABSTRACT: Chronic obstructive pulmonary disease (COPD) independently associates with an increased risk of coronary artery disease (CAD), but it has not been fully investigated whether this co-morbidity involves shared pathophysiological mechanisms. To identify potential common pathways across the two diseases, we tested all recently published single nucleotide polymorphisms (SNPs) associated with human lung function (spirometry) for association with carotid intima-media thickness (cIMT) in 3,378 subjects with multiple CAD risk factors, and for association with CAD in a case-control study of 5,775 CAD cases and 7,265 controls. SNPs rs2865531, located in the CFDP1 gene, and rs9978142, located in the KCNE2 gene, were significantly associated with CAD. In addition, SNP rs9978142 and SNP rs3995090 located in the HTR4 gene, were associated with average and maximal cIMT measures. Genetic risk scores combining the most robustly spirometry-associated SNPs from the literature were modestly associated with CAD, (odds ratio (OR) (95% confidence interval (CI95) = 1.06 (1.03, 1.09); P-value = 1.5×10-4, per allele). In conclusion, our study suggests that some genetic loci implicated in determining human lung function also influence cIMT and susceptibility to CAD. The present results should help elucidate the molecular underpinnings of the co-morbidity observed across COPD and CAD.

    ABSTRACT: The study hypothesis was that thoracic aortic disease (TAD) is associated with a higher-than-expected prevalence of inguinal hernia. Such an association has been reported for abdominal aortic aneurysm (AAA) and hernia. Unlike AAA, TAD is not necessarily detectable with clinical examination or ultrasound, and there are no population-based screening programs for TAD. Therefore, conditions associated with TAD, such as inguinal hernia, are of particular clinical relevance.

    ABSTRACT: Cardiac left ventricle hypertrophy (LVH) constitutes a major risk factor for heart failure. Although LVH is most commonly caused by chronic elevation in arterial blood pressure, reduction of blood pressure to normal levels does not always result in regression of LVH, suggesting that additional factors contribute to the development of this pathology. We tested whether genetic preconditions associated with the imbalance in sodium homeostasis could trigger the development of LVH without concomitant increases in blood pressure. The results showed that the presence of a hypertensive variant of α-adducin gene in Milan rats (before they become hypertensive) resulted in elevated expression of genes associated with LVH, and of salt-inducible kinase 2 (SIK2) in the left ventricle (LV). Moreover, the mRNA expression levels of SIK2, α-adducin, and several markers of cardiac hypertrophy were positively correlated in tissue biopsies obtained from human hearts. In addition, we found in cardiac myocytes that α-adducin regulates the expression of SIK2, which in turn mediates the effects of adducin on hypertrophy markers gene activation. Furthermore, evidence that SIK2 is critical for the development of LVH in response to chronic high salt diet (HS) was obtained in mice with ablation of the sik2 gene. Increases in the expression of genes associated with LVH, as well as increases in LV wall thickness upon HS, occurred only in sik2+/+ but not in sik2-/- mice. Thus LVH triggered by HS or the presence of a genetic variant of α-adducin requires SIK2 and is independent of elevated blood pressure. Inhibitors of SIK2 may constitute part of a novel therapeutic regimen aimed at prevention/regression of LVH.

    ABSTRACT: Background The aim of this study was to explore possible differences in aortic strain, distensibility, and stiffness in the descending thoracic aorta between patients with bicuspid aortic valves (BAVs) and those with tricuspid aortic valves (TAVs) in relation to type of aortic valve disease and known cardiovascular risk factors. Methods Transesophageal echocardiography was used to examine 288 patients (mean age, 64 ± 13 years) in the operating room before surgery. The transesophageal echocardiographic images were analyzed offline using Velocity Vector Imaging software. One hundred forty patients had isolated severe aortic stenosis (AS) (89 of those with BAVs, 51 of those with TAVs), and 52 patients had isolated severe aortic regurgitation (AR) (24 of those with BAVs, 28 of those with TAVs). Results In patients with AS, stiffness in the descending aorta was 10 (range, 7.3–16) in those with BAVs and 13 (range, 11–18) in those with TAVs (P < .001). Distensibility was 19 kPa−1 10−3 (range, 13–27 kPa−1 10−3) in patients with BAVs and 15 kPa−1 10−3 (range, 11–19 kPa−1 10−3) in those with TAVs (P < .01). In patients with AR, stiffness was 6.9 (range, 5.5–7.8) in those with BAVs and 8.0 (range, 6.6–11) in those with TAVs (P < .05). After correction for age, dimension of the ascending aorta, cholesterol, and stroke volume in a multivariate regression model, BAV was associated with lower strain and distensibility of the descending aorta in the AR group and higher distensibility in the AS group, whereas stiffness was no longer related to aortic valve morphology in either of the two groups. Conclusions The presence of BAVs in patients with severe AR is associated with lower strain and distensibility, suggesting that impairment of the elastic aortic properties may extend to the descending aorta. In patients with AS, BAVs correlate weakly with higher distensibility.

    ABSTRACT: Ceramides are poorly characterized in human adipose tissue. The aim of this study was to investigate concentrations of different ceramide species in human subcutaneous and visceral adipose tissue depots and to determine associations between ceramides and global gene expression profiles. Concentrations of six ceramide species were determined in plasma and in subcutaneous and mediastinal adipose tissue from 10 overweight subjects (BMI 29.4 ± 4.9 kg/m(2)). In the adipose tissue biopsies gene expression arrays were performed and relationships between ceramides and gene expression analyzed. Immunostaining of the two adipose tissue depots was performed in an independent group of 10 patients. Mediastinal adipose tissue contained significantly higher concentrations (p < 0.05) of all six ceramide species than the subcutaneous depot. Of the six ceramides in plasma, concentrations of only two (Cer d18:1/18:0 and Cer d18:1/22:0) correlated significantly (p < 0.05) with the corresponding species in mediastinal adipose tissue, but there were no significant correlations between ceramides in plasma and subcutaneous adipose tissue. Multivariate analysis identified significant correlations between the total ceramide concentration and global gene expression within mediastinal, but not subcutaneous adipose tissue, according to cross-validation. Gene ontology analysis of genes related to ceramides in the mediastinal depot revealed that genes positively correlated with ceramides were associated mainly with immune and inflammatory categories, while genes negatively correlated with ceramides were associated mainly with lipid and carbohydrate metabolism. Ceramides in human mediastinal adipose tissue may be involved in inflammation and lipid and carbohydrate metabolism.

    ABSTRACT: Sjögren's syndrome is a common autoimmune disease (affecting ∼0.7% of European Americans) that typically presents as keratoconjunctivitis sicca and xerostomia. Here we report results of a large-scale association study of Sjögren's syndrome. In addition to strong association within the human leukocyte antigen (HLA) region at 6p21 (Pmeta = 7.65 × 10(-114)), we establish associations with IRF5-TNPO3 (Pmeta = 2.73 × 10(-19)), STAT4 (Pmeta = 6.80 × 10(-15)), IL12A (Pmeta = 1.17 × 10(-10)), FAM167A-BLK (Pmeta = 4.97 × 10(-10)), DDX6-CXCR5 (Pmeta = 1.10 × 10(-8)) and TNIP1 (Pmeta = 3.30 × 10(-8)). We also observed suggestive associations (Pmeta < 5 × 10(-5)) with variants in 29 other regions, including TNFAIP3, PTTG1, PRDM1, DGKQ, FCGR2A, IRAK1BP1, ITSN2 and PHIP, among others. These results highlight the importance of genes that are involved in both innate and adaptive immunity in Sjögren's syndrome.

    ABSTRACT: -Abdominal aortic aneurysm (AAA) is a common cardiovascular disease among older people and demonstrates significant heritability. In contrast to similar complex diseases, relatively few genetic associations with AAA have been confirmed. We reanalysed our genome-wide study and carried through to replication suggestive discovery associations at a lower level of significance. -A genome-wide association study was conducted using 1,830 cases from the UK, New Zealand and Australia with infra-renal aorta diameter ≥30mm or ruptured AAA and 5,435 unscreened controls from the 1958 Birth Cohort and National Blood Service cohort from the Wellcome Trust Case Control Consortium. Eight suggestive associations with P<1x10(-4) were carried through to in silico replication in 1,292 AAA cases and 30,503 controls. One SNP associated with P<0.05 after Bonferroni correction in the in silico study underwent further replication (706 AAA cases and 1,063 controls from the UK, 507 AAA cases and 199 controls from Denmark and 885 AAA cases and 1,000 controls from New Zealand). Low density lipoprotein receptor (LDLR) rs6511720 A, was significantly associated overall and in three of five individual replication studies. The full study showed an association that reached genome-wide significance (odds ratio 0.76; 95% confidence interval 0.70 to 0.83; P=2.08x10(-10)). -LDLR rs6511720 is associated with abdominal aortic aneurysm. This finding is consistent with established effects of this variant on coronary artery disease. Shared aetiological pathways with other cardiovascular diseases may present novel opportunities for preventative and therapeutic strategies for AAA.
