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).

For the analysis of miRNA expression changes after ET-1 stimulation, single-end small RNA sequencing was performed using the Ion Torrent Personal Genome Machine (PGMTM) sequencing platform.

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:Human induced pluripotent stem cell (iPSC)-derived cardiomyocytes cultured in 3-dimensional suspension culture were treated with AS1842856 FOXO-inhibitor (n=3 independent wells) or DMSO vehicle control (n=3 independent wells). Total RNA was isolated from each well and utilized for RNA sequencing.

Project description:Analysis of human iPS-derived cardiomyocytes exposed to glucose, endothelin-1 and cortisol in vitro. Treatment produces a surrogate diabetic cardiomyopathic phenotype. Results provide insight into the pathways regulated by the treatment in the cardiomyocyte. The RNA for each vehicle-control treated and glucose endothelin cortisol treated iPS derived cardiomyocytes from 4 replicate samples, were extracted and hybridized to 8 individual human HG-U133 Plus2.0 Affymetrix microarray gene chips, whereby each chip represented the expression profile for one cell culture at 2 days.

Project description:This study aimed to simulate chronic CCB treatment and to examine both the functional and transcriptomic changes in human cardiomyocytes. We differentiated cardiomyocytes from three human induced pluripotent stem cell (iPSC) lines and exposed them to four different CCBs—nifedipine, amlodipine, diltiazem, and verapamil—at their physiological serum concentrations for two weeks. Without inducing cell death and damage to myofilament structure, CCBs elicited line specific inhibition on calcium kinetics and contractility. While all four CCBs exerted similar inhibition on calcium kinetics, verapamil applied the strongest inhibition on cardiomyocyte contractile function. By profiling cardiomyocyte transcriptome after CCB treatment, we identified little overlap in their transcriptome signatures. Verapamil is the only inhibitor that reduced the expression of contraction related genes, such as myosin heavy chain and troponin I, consistent with its depressive effects on contractile function. This is the first study to identify the transcriptome signatures of different CCBs in human cardiomyocytes. The distinct gene expression patterns suggest that although the four inhibitors act on the same target, they may have distinct effects on normal cardiac cell physiology.

Project description:Dilated cardiomyopathy (DCM) is the leading cause of heart failure and transplantation worldwide. We used iPSCs to model this disease and compared gene expression change before and after gene therapy of cardiomyocytes derived from DCM-specific iPSCs. We used microarrays to detail the global gene expression of patient specific iPSCs, iPSC-derived cardiomyocytes and its response to gene therapy. Skin fibroblasts and iPSCs derived from a family exhibiting familial dilated cardiomyopathy and H7 human ESCs were subjected to RNA extraction and hybridization on Affymetrix microarrays.Global gene expression pattern were compared and analyzed. Cardiomyocytes derived from iPSCs generated from this DCM family were treated with or without adenoriral Serca2a and subjected to RNA extraction and hybridization on Affymetrix microarrays. Global gene expression pattern were compared and analyzed.
