Project description:Arrhythmogenic cardiomyopathy (AC) is an inherited cardiomyopathy characterized by fibrofatty replacement predominantly involved in right ventricle and clinically by ventricular arrhythmias.In this study, we set out to characterize the cardiac novel long-noncoding RNAs using deep RNA sequencing data from human heart tissues. Particularly, we identified AC specific novel lncRNAs that contribute to AC pathophysiology by comparing the lncRNAs transcripts of nine AC explanted hearts (RV), five non-diseased donor hearts (RV), four non-AC failing hearts (dilated cardiomyopathy, RV). To dissect the roles of novel lncRNAs in ARVC from LV, we also include six non-diseased donor hearts (LV) and six ARVC explanted hearts (LV) in the analysis. In the identified novel AC lncRNAs, a large part of them are derived from enhancer regions and acting as cis- elements to potentially regulate lipogenesis or lipid metabolism related genes. Finally, we validated several of these AC specific novel lncRNAs and their potential targets in independent patient samples. Collectively, we identified high-confidence AC specific novel lncRNAs from human samples and suggest their potential roles as cis- elements in AC pathology. Further study of these novel AC lncRNAs could provide new opportunities for diagnosis and therapeutic intervention.

Project description:Background: Right ventricular (RV) and left ventricular (LV) myocardium differ in their response to pressure-overload hypertrophy (POH). In this report we use microarray and proteomic analyses to identify pathways modulated by LV-, and RV-POH in the immature heart. Methods: Newborn New Zealand White rabbits underwent banding of the descending thoracic aorta (LV-POH; n=6). RV-POH was achieved by banding the pulmonary artery (n=6). Sham–control animals (SC; n=6 each) were sham-manipulated. Following 4 (LV-POH) and 6 weeks (RV-POH) recovery, the hearts were removed and matched sample RNA and proteins were isolated for microarray and proteomic analysis. Results: There was no difference in body weight in RV-, LV-POH vs. SC but there was a significant increase vs. SC in RV (3.2±0.8g vs. 1.2±0.3g; P<0.01) and LV weight (7.08±0.6g vs. 4.02±0.2g; P<0.01). Fractional area change (RV-POH) and shortening fraction (LV-POH) decreased significantly (23±6 vs. 47±6 and 21±4 vs.44±2, respectively, P<0.01). Microarray analysis demonstrated that LV-POH enriched pathways for oxidative phosphorylation, mitochondria energy pathways, actin, ILK, hypoxia, calcium and protein kinase-A signalling. RV-POH enriched pathways for cardiac oxidative phosphorylation. Proteomic analysis revealed 19 proteins were uniquely expressed in LV-POH vs. SC. Functional annotation clustering analysis indicated significant enrichment for the mitochondrion, cellular macromolecular complex assembly and oxidative phosphorylation. RV-POH had 15 uniquely expressed proteins vs. SC. Functional annotation clustering analysis indicated significant enrichment in structural constituents of muscle, cardiac muscle tissue development and calcium handling. Conclusion: Our results identify unique transcript and protein expression profiles in LV, RV-POH and provide new insight into the biological basis of ventricular specific hypertrophy. 3 different conditions: PAB-RV vs. Sham-control RV, PAB-RV [test] vs. PAB-LV [control], AOB-LV vs. Sham-control LV.

Project description:Background: Lamins A/C (encoded by the LMNA gene) can lead to dilated cardiomyopathy (DCM). Objectives: This study sought to undertake proteomic analysis of myocardial tissue to explore the postgenomic phenotype of end-stage lamin heart disease. Methods: Consecutive patients with end-stage lamin heart disease (LMNA-group, n=7) and ischaemic DCM (ICM-group, n=7) undergoing heart transplantation were enrolled. Samples were obtained from left atrium(LA), left ventricle(LV), right atrium(RA), right ventricle(RV) and interventricular septum(IVS). Liquid chromatography combined with mass-spectrometry was used for protein quantification. We compared protein concentrations in cardiac samples between LMNA and ICM groups. Proteins were considered differentially abundant if the quantitative difference was 1.5-fold and corrected p-value <0.05 at a false discovery rate of 0.01. Gene ontology(GO) enrichment analysis explored the related biological processes. Results: 4,247 proteins were identified in LMNA and ICM samples, of which 633 were differentially abundant in LA, 39 in LV, 181 in RA, 52 in RV, and 85 in IVS. Abundance of lamin A/C was reduced but lamin B (LMNB) increased in LMNA LA/RA tissue compared to ICM, but not in LV/RV. Transthyretin was more abundant in the LV/RV of LMNA compared to ICM while sarcomeric proteins such as titin and cardiac myosin heavy chain were generally reduced in RA/LA of LMNA. Protein expression profiling and GO enrichment analysis revealed sarcopenia, extracellular matrix(ECM) remodeling, deficient myocardial energetics, redox imbalances, and abnormal calcium handling in LMNA samples. Conclusion: Lamin heart disease is a biventricular and biatrial disease, characterized by sarcopenia, aberrant metabolism, and ECM remodeling. LMNB and transthyretin were unexpectedly abundant in the atria and ventricles respectively of patients with end-stage lamin heart disease potentially hinting to the possibility of compensatory responses.
