Project description:The study aims to develop an in vitro model of cardiac hypertrophy using human induced pluripotent stem cells (hPSCs). Human stem cell based disease models are important for reducing the number of animals used in research and to get data the is more relevant to humans. We stimulated hiPSCs derived cardiomyocytes with endothelin-1 for up to 96 hours and investigated to the hypertrophic response. We measured gene expression using RNA-seq, ANP and proBNP protein, lactate and cell size.

Project description:Cardiac hypertrophy is an independent risk factor for cardiovascular disease and heart failure. There is increasing evidence that microRNAs (miRNAs) play an important role in the regulation of messenger RNA (mRNA) and the pathogenesis of various cardiovascular diseases. However, the ability to comprehensively study cardiac hypertrophy on a gene regulatory level is impacted by the limited availability of human cardiomyocytes. Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) offer the opportunity for disease modeling. We utilized a previously established in vitro model of cardiac hypertrophy to interrogate the regulatory mechanism associated with the cardiac disease process. We performed miRNA sequencing and mRNA expression analysis on endothelin 1 (ET-1) stimulated hiPSC-CMs to describe associated RNA expression profiles. MicroRNA sequencing revealed over 250 known and 34 predicted novel miRNAs to be differentially expressed between ET-1stimulated and unstimulated control hiPSC-CMs. Messenger RNA expression analysis identified 731 probe sets with significant differential expression. Computational target prediction on significant differentially expressed miRNAs and mRNAs identified nearly 2000 target pairs. To characterize miRNA and mRNA expression patterns we utilized iCell Cardiomyocytes derived from human iPSCs (hiPSC-CMs). Based on preliminary dose-response and time-course studies, we stimulated these cells with ET-1 at 10-8M for 18h. We used unstimulated control (control-CM) and ET-1 stimulated (ET1-CM) hiPSCs from 3 separate experiments as triplicate data for this study. mRNA expression for the control-CM and ET1-CM samples was analyzed using GeneChip 3M-bM-^@M-^YIVT express arrays (Affymetrix).

Project description:Cardiac hypertrophy consists in the enlargement of cardiomyocytes and alteration of the extracellular matrix organization in response to physiological or pathological stress. In pathological hypertrophy ocuurs myocardial damage, loss of cardiomyocytes, fibrosis, inflammation, sarcomere disorganization and metabolic impairment, leading to cardiac dysfunction.The rodent model treated with isoproterenol induces cardiac hypertrophy due the constant activation of β-adrenergic receptors. We conducted a quantitative label-free proteomic analysis of cardiomyocytes isolated from hearts of mice treated or not with isoproterenol to better understand the molecular bases of cellular response due to isoproterenol-induced injury.

Project description:Pathological cardiac hypertrophy can lead to heart failure and is one of the leading causes of death globally. Understanding the molecular mechanism of pathological cardiac hypertrophy will contribute to the treatment of heart failure. Deubiquitinating enzymes (DUBs) are essential to cardiac pathophysiology by precisely controlling protein function, localization, and degradation.This study set out to investigate the role of a DUB, USP25, in pathological cardiac hypertrophy, reveal its molecular mechanism, and hopefully provide a new therapeutic target for heart failure.We revealed increased protein level of USP25 expression in the cardiomyocytes in response to Ang II stimulation. USP25 deficiency aggravated cardiac hypertrophy and cardiac dysfunction under Ang II and TAC treatment. Mechanistically, LC-MS/MS analysis combined with Co-IP was used to identify SERCA2a, an anti-hypertrophy protein, as an interacting protein of USP25. Also, our data showed that USP25 bound to SERCA2a directly via its USP domain and cysteine at position 178 of USP25 exerts deubiquitination to maintain the stability of the SERCA2a protein by removing the K48 ubiquitin chain and preventing proteasomal pathway degradation, thereby maintaining calcium content in cardiomyocytes. Moreover, restoration of USP25 expression via with AAV9 vectors in USP25-/- mice attenuated Ang II-induced cardiac hypertrophy and cardiac dysfunction, whereas SERCA2a myocardial overexpression could offset the effect of USP25.

Project description:Cardiac hypertrophy is an important and independent risk factor for the development of cardiac myopathy that may lead to heart failure. Cardiac hypertrophy manifests as an enlargement of the individual cardiomyocytes, which impairs the function of the heart. The only way to cure end-stage cardiac myopathy is by heart transplantation, a possibility limited due to lack of donor hearts. Therefore, early diagnosis of cardiac hypertrophy is needed in order to be able to initiate interventions that may prevent further progression of the disease. The mechanisms underlying the development of cardiac hypertrophy are yet not well understood. To increase the knowledge about mechanisms and regulatory pathways involved in the progression of cardiac hypertrophy, we have developed a human induced pluripotent stem cell (hiPSC)-based in vitro model of cardiac hypertrophy and performed extensive characterization of the model using multi-omics analyses. In a series of experiments, hiPSC-derived cardiomyocytes were stimulated with Endothelin-1 for 8, 24, 48 and 72 hours and their transcriptome and secreted proteome were analyzed thoroughly. The transcriptomic data show many enriched canonical pathways related to cardiac hypertrophy already at the earliest time point, e.g., cardiac hypertrophy signaling, actin cytoskeleton signaling and PI3K/AKT signaling. Cluster analysis of the differentially expressed genes showed that there are numerous clusters of genes that are dysregulated over the time period of 8 to 72h. An integrated transcriptome-secretome analysis enabled the identification of multimodal biomarkers of high relevance for monitoring early cardiac hypertrophy progression. Taken together, the results from this study demonstrate that our in vitro model displays a hypertrophic response on transcriptomic- and secreted proteomic level. The results also provide novel insight into the underlying mechanisms of cardiac hypertrophy and novel putative early cardiac hypertrophy biomarkers have been identified that will be further validated to assess their clinical relevance.
