NHLBI TOPMed: Cleveland Clinic Atrial Fibrillation (CCAF) Study

ABSTRACT:

The Cleveland Clinic Atrial Fibrillation Study consists of clinical and genetic data of patients with atrial fibrillation and control cohorts from the Cleveland Clinic CV/Arrhythmia Biobank, including the Cleveland Clinic Lone Atrial Fibrillation GeneBank. The Cleveland Clinic Lone AF GeneBank Study has enrolled patients with lone AF, defined as AF in the absence of significant structural heart disease. The CV/Arrhythmia Biobank has also enrolled participants with non-lone atrial fibrillation. All patients provided written informed consent.

Changes of ubiquitylated proteins in atrial fibrillation associated with heart valve disease: proteomics in human in left appendage tissue

Project description:Atrial fibrillation (AF) is the most common persistent arrhythmia that affect 1–2% of the general population. People with AF display an array of complications cardiogenic stroke and systemic embolism caused by hemodynamic instability and blood hypercoagulability in clinical practice. However, it’s still unclear whether and how ubiquitylated proteins react to AF in the left atrial appendage of patients with AF and valvular heart disease. This theory focuses on the changes of ubiquitylated proteins in atrial fibrillation associated with heart valve disease. We firstly widely analysis the proteins ubiquitination in patients with atrial fibrillation.

Comparison of atrial appendage tissues of patients with Valvular Heart Disease and patients with Valvular Heart Disease-Atrial Fibrillation

Project description:Atrial fibrillation (AF) is the most common heart arrhythmia disease. The greatest risk of atrial fibrillation is stroke, and stroke caused by valvular heart disease with atrial fibrillation (AF-VHD) is more serious. the development mechanism from VHD to AF-VHD is not yet clear. The research on expression profiles of lncRNA and mRNA is helpful to explore molecular mechanism in patients with valvular heart disease who develop atrial fibrillation.

Integrated Analysis of Dysregulated lncRNA and mRNA Expression profiles of myocardial sleevesof pulmonary veins in atrial fibrillation

Project description:Atrial fibrillation (AF) is currently the most prevalent arrhythmia worldwide.Recent clinical data implicate the additional contribution of non-coding RNAs in the pathogenesis of AFï¼which include microRNAs(miRNAs), endogenous small interfering RNAs, PIWIinteracting RNAs, and lncRNA. Notably, a growing number of lncRNAs have been implicated in disease etiology, although an association with AF has not been reported. In the present study, we conducted an integrated analysis of dysregulated lncRNA and mRNA expression profiles in myocardial sleevesof pulmonary veins between the patients who develop AF and the patients who were in normal sinus rhythm, which was performed using a second generation lncRNA microarrayï¼focusing specifically on the identification and characterization of lncRNAs and mRNA potentially involving in maintaining atrial fibrillation. We conducted an integrated analysis of myocardial sleeves of pulmonary veinsï¼PVsï¼from 12 patients (6 non-AF and 6AF) in our center, of which hypertension, diabetes, smoking and alcohol abuse were excluded, using a second generation lncRNA microarray

Genome-wide DNA methylation analysis in permanent atrial fibrillation

Project description:Atrial fibrillation (AF) is the most common sustained arrhythmia with increased risk of stroke and congestive heart failure. AF is a highly genetic heterogeneous disease, but a large proportion of AF cannot be explained by genetic variants only. Some risk factors of AF, tendentious heritable phenomenon, potentially reversible conditions and some subtypes without DNA sequence variation all indicate the participation of DNA methylation in the pathogenesis of AF. Bisulphite converted DNA from the 11 left atrium samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip GPL13534

Single-cell profile of atrial human fibroblasts in cardiac arrhythmia atrial fibrillation (AF) - 10x

Project description:Atrial fibrillation (AF), the most common cardiac arrhythmia, is a major contributor to population mortality and morbidity. The goal of this study is to explore molecular mechanisms of the AF-induced profibrotic remodelling in human atrial fibroblasts (ACFs). Specifically, we assessed single-cell transcriptome of cultured human ACFs treated with calcitonin(CT) or vehicle (from 6 individual patients) and of freshly-isolated ACFs from patients with AF (4 individual patients) vs controls (4 individual patients). We found that ACF transcriptome was unaltered by CT in cultured ACFs, and identified 5 transcriptional clusters with 23 differentially expressed transcripts in AF in freshly-ioslated ACFs.

Sequencing in Over 50,000 Cases Identifies Coding and Structural Variation Underlying Atrial Fibrillation Risk

Project description:Atrial fibrillation (AF) is a prevalent and morbid abnormality of the heart rhythm with a strong genetic component Here, we meta-analyzed genome and exome sequencing data from 36 studies that included 52,416 AF cases and 277,762 controls In burden tests of rare coding variation, we identified novel associations between AF and the genes MYBPC3, LMNA, PKP2, FAM189A2 and KDM5B We further identified associations between AF and rare structural variants due to deletions in CTNNA3 and duplications of GATA4 We broadly replicated our findings in independent samples from MyCode, deCODE and UK Biobank Finally, we found that CRISPR-knockout of KDM5B in stem cell derived atrial cardiomyocytes led to a shortening of the action potential duration and widespread transcriptomic dysregulation of genes relevant to atrial homeostasis and conduction Our results highlight the contribution of rare coding and structural variants to AF, the genetic link between AF and cardiomyopathies, and expand our understanding of the rare variant architecture for this common arrhythmia

The goal of this study is to explore molecular mechanisms of the AF-induced profibrotic remodelling in human atrial fibroblasts (ACFs). Specifically, we assessed single-cell transcriptome of cultured human ACFs treated with calcitonin(CT) or vehicle (from 6 individual patients) and of freshly-isolated ACFs from patients with AF (4 individual patients) vs controls (4 individual patients) (SR). We found that ACF transcriptome was unaltered by CT in cultured ACFs, and identified 5 transcriptional clusters with 23 differentially expressed transcripts in AF in freshly-ioslated ACFs.
