NGS-based miRNome profile in cardiac muscle tissue of congenital heart disease patients

ABSTRACT: The goal of this study was to explore the miRNome profile in three frequently occurring Congenital Heart Disease (CHD) types, namely Atrial Septal Defect (ASD), Ventricular Septal Defect (VSD) and Tetralogy of Fallot (TOF). For this purpose, we extracted total RNA from the cardiac tissues of patients with CHD and non-CHD, which was subjected to high-throughput sequencing technology to profile the miRNAs. The small RNA sequencing data was analyzed using the nf-core bioinformatic analysis pipeline. There were 40 up-regulated and 8 down-regulated miRNAs identified to be differentially expressed. These miRNAs are predicted to target several genes involved in regulatory pathways such as cell proliferation, differentiation, cell survival, etc. The results from this study are expected to expand the existing knowledge on molecular basis of CHD. Functional validation can throw insights on molecular epidemiology and therapy for heart diseases.

Comparative DNA methylation and gene expression analysis identifies novel genes for structural congenital heart diseases

Project description:The most common congenital heart disease (CHD) is the ventricular septal defect (VSD), which is also a subfeature of Tetralogy of Fallot (TOF) representing the most common form of cyanotic CHD. The underlying causes for the majority of CHDs are still unclear and most probably consist of combinations of genetic, epigenetic and environmental factors. DNA methylation is the most widely studied epigenetic modification and several cardiac regulators have already been shown to be differentially methylated in CHD patients. Here, we present the first analysis of genome-wide DNA methylation data obtained from cardiac biopsies of TOF and VSD patients. We applied affinity-based enrichment of methylated DNA sequences with methyl-CpG-binding domain proteins followed by next-generation sequencing (MBD-Seq).

Circulating MicroRNA: Myocardium-Derived Prenatal Biomarker of Ventricular Septal Defects

Project description:MicroRNAs (miRNAs) regulate transcription factors and relate to ventricular septal defect (VSD) occurrence, progression and outcome. Recently, circulating miRNAs from maternal blood and amniotic fluid have been used as biomarkers for congenital heart defect (CHD) diagnosis. However, whether circulating miRNAs are associated with foetal heart tissue remains unknown. Dimethadione (DMO) induced a VSD rat model and the miRNA expression profiles of the myocardium, amniotic fluid and maternal serum were analysed. MiRNAs were differentially expressed in the myocardium, amniotic fluid or maternal serum of VSD foetal rats and might be involved in cardiomyocyte differentiation and apoptosis.

Whole genome microarray gene expression profiling of right ventricular heart specimens from pediatric patients with Tetralogy of Fallot (TOF)

Project description:Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect with a world-wide prevalence of 3 to 4 cases per 10,000 life births. TOF is a congenital heart disease with four major cardiac defects, i.e., ventricular septal defect, overriding aortic root, infundibular stenosis of the pulmonary artery, and right ventricular hypertrophy. Treatment relies on correction surgery in early infancy. This study performed whole genome microarray gene expression profiling of cardiac specimens of the right ventricular outflow tract (RVOT), which were recovered during correction surgery of TOF from 11 pediatric patients diagnosed with TOF cardiac defects.

Analysis of Amniotic Fluid-derived lncRNAs and mRNAs in Fetuses with ventricular septal defect

Project description:Ventricular septal defect (VSD) is one of the most prevalent birth defects. The pathogenesis of VSD remains unknown. to analyze the expression of AF-derived lncRNAs and their roles in VSD development, Arraystar Human LncRNA Microarray V5.0 is employed for the global profiling of human lncRNAs and protein-coding transcripts.

Analysis of Amniotic Fluid-Derived Exosomal miRNAs in Fetuses with Tetralogy of Fallot

Project description:Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease (CHD). Amniotic fluid (AF) contains a higher abundance of biological compounds which could direct reflect the information of fetal health. AF-derived exosomal miRNAs have been investigated as etiological factors in the pathogenesis of TOF. The purpose of this study was to analyze the expression of AF-derived exosomal miRNAs and their roles in TOF development. In this study, we identified differentially expressed (DE)-miRNAs between TOF group and control group. A total of 257 miRNAs were differentially expressed (DE) between TOF and control groups. KEGG pathway enrichment demonstrated that these target genes of DE-miRNAs were involved in Wnt and Notch signaling pathway. Twenty five of 257 DE-miRNAs were overlapped with Notch-regulated and Wnt-regulated miRNAs simultaneously.

Integrated multiomic characterization of congenital heart disease [RNA-Seq]

Project description:The heart, the first organ to develop, undergoes complex morphogenesis that when defective results in congenital heart disease (CHD). With current therapies, more than 90% of CHD patients survive into adulthood but often suffer premature death from heart failure (HF) and non-cardiac causes 1. To gain insight into poorly understood disease progression, we performed single nuclear RNA sequencing (snRNA-seq) and analyzed more than 157,000 nuclei from donors and CHD patients, including hypoplastic left heart syndrome (HLHS) and Tetralogy of Fallot (TOF), two common forms of cyanotic CHD lesions, as well as, dilated (DCM) and hypertrophic (HCM) cardiomyopathies. We observed CHD specific cell states in cardiomyocytes (CMs) which had evidence of insulin resistance and increased FOXO and CRIM1 expression. Cardiac fibroblasts (CFs) in HLHS had enrichment for a low HIPPO and high YAP cell state characteristic of activated CFs. Imaging Mass Cytometry (IMC) uncovered the spatially resolved perivascular microenvironment consistent with an immunodeficient state in CHD. Peripheral immune cell profiling suggested deficient monocytic immunity in CHD in agreement with CHD predilection to infection and cancer 2. Our comprehensive CHD phenotyping provides a roadmap for future personalized medicine in CHD.

Deregulation of miRNAs in Infant Outflow Tract Myocardium of Non-syndromic Tetralogy of Fallot

Project description:Tetralogy of Fallot (TOF) is one of the most common heart defects in children and the underlying mechanisms remain elusive. miRNAs are a recently discovered class of regulators of gene expression and are becoming increasingly recognized as important regulators of heart development and function. The objective of the present study was to identify miRNAs that are abnormally expressed in clinical infant outflow tract myocardium tissues of TOFs.
