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.

Project description:We generated maps of H3K4me1, H3K27ac (enhancers), H3K4me3, Pol II (promoters) and H3K27me3 (repressed chromatin) in the genome of human iPSC-derived cardiomyocytes Differentiation of cardiomyocytes from iPSC followed by ChIP-seq of H3K27ac, H34me1, H327me3, H3K4me3 and PolII
Project description:We generated an interaction map using capture in situ Hi-C in human iPSC-derived cardiomyocytes Differentiation of cardiomyocytes from iPSC followed by capture in situ Hi-C
Project description:Analysis of human iPSC-derived cardiomyocytes unstimulated or stimulated with endothelin-1 in the presence of either vehicle (DMSO), Ivermectin, Importazole, IPA-3, or verapamil. Results provide insight into the pathways regulated by the treatments.
Project description:Chemical warfare nerve agents (CWNA) are potent cholinesterase inhibitors that may also have non-cholinesterase effects. Several in vivo studies have shown that exposure to CWNA compounds induces damage in the brain and heart. Underlying mechanisms of this damage are a critical area of research for the development of medical countermeasures. This study utilized microRNA (miRNA) analysis to evaluate potential direct cellular effects of the nerve agent VX (o-ethyl-s-[2 (diisopropylamino) ethyl]) on human (iPSC)-derived neurons and iPSC-derived cardiomyocytes. iPSC-derived cardiomyocytes were treated with VX at concentrations of 0µM (saline control), 0.1µM or 100µM for either 1 hour or 6 hours. Total RNA was then isolated and processed for miRNA microarray analysis using Affymetrix miRNA 2.0 GeneChips
