(Submitter supplied) 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.

Analysis of DCM iPSC-derived cardiomyocytes treated with sarcoplasmic reticulum Ca2+ adenosine triphosphatase (Serca2a). Serca2a treatment improved the function of these cardiomyocytes. Results provide insight into the molecular basis of Serca2a-mediated repair of DCM iPSC-derived cardiomyocytes.

(Submitter supplied) iPSC-derived cardiomyocytes (iPSC-CMs) have enormous potential for the study of human cardiac disorders. However, their physiological immaturity severely limits their utility as a model system and their adoption for drug discovery. In this study, we describe a maturation media (MM) designed to provide oxidative substrates adapted to the metabolic needs of hiPSC-CMs as compared to standard RPMI/B27 media. more...

(Submitter supplied) To investigate the physiological characteristics of cardiomyocytes (CM) in restrictive cardiomyopathy (RCM), we established RCM(heterozygous)-iPSC and produced RCM(homozygous)-iPSC and corrected Isogenic-iPSC using CRISPER-CAS9 technology. Then, we used the RNA-seq data obtained from these three iPSCs and three different healthy iPSC-derived CMs for gene expression profiling analysis.

(Submitter supplied) Purpose: LMNA-DCM accounts for 5-10% of DCM cases and has an age-related penetrance whose onset typically appears between the ages of 30 and 40. However, the precise mechanisms linking the LMNA mutation to increased arrhythmogenicity are still unknown. Methods: We utilized human iPSC-CMs RNA-seq, ChIP-seq, and ATAC-seq technologies. Results: The electrophysiological studies of iPSC-CMs identify the LMNA mutation as a cause of increased arrhythmogenicity in mutant iPSC-CMs through abnormal calcium homeostasis. more...

(Submitter supplied) Mutations in RNA binding motif protein 20 (RBM20) are a common cause of dilated cardiomyopathy (DCM). Many RBM20 mutations cluster within an arginine/serine rich (RS-rich) domain, resulting in mis-localization of RBM20 to ribonucleoprotein granules within the cytoplasm, abnormal splicing of cardiac genes, and cardiomyocyte dysfunction. We used adenine base editing (ABE) and prime editing to correct pathogenic p.R634Q and p.R636S mutations in the RS-rich domain in human isogenic induced pluripotent stem cell-derived cardiomyocytes. more...

(Submitter supplied) Titintruncating variants(TTNtv) have been identified as the single largestgenetic cause of dilated cardiomyopathy(DCM). In this studywe modeled the disease phenotypes of TTNtv-induced DCM in hiPSC-CMsusing CRISPR/Cas9 genome editing and tissue engineering technologies. Transcriptomic, cellular and micro-tissue studies revealed that TTNtv hiPSC-CMs displayed pathogenic proteinopathy, sarcomere defects, aberrant Na+channel activities and, most importantly, contractile dysfunction. more...

(Submitter supplied) Different single mutations on the same sarcomeric gene often cause distinct cardiomyopathy phenotypes as dilated (DCM) or hypertrophic cardiomyopathy (HCM). The key factors involved in this disease divergence is unknown and could be key for disease intervention.We generated isogenic familial DCM and HCM disease-specific human embryonic stem cells (hESCs) carrying the cTnT-DK210 and -DE160 mutation, respectively. more...

(Submitter supplied) The cTnT-DK210 DCM mice showed ABRA protein deficiency, sarcomeric disruption, and compromised heart contractility. Heart-specific expression of ABRA in cTnT-DK210 mice restored sarcomeric structures, reversed the disease progress, and rescued the DCM phenotypes. ABRA deficiency and compromised downstream serum response factor-regulated muscle gene expression play a key role in familial DCM caused by the cTnT-DK210 mutation. more...

(Submitter supplied) Dilated cardiomyopathy (DCM) is the most common form of cardiomyopathy and main indication for heart transplantation in children. Therapies specific to pediatric DCM remains limited due to lack of a disease model. Our previous study showed that treatment of neonatal rat ventricular myocytes (NRVMs) with non-failing or DCM pediatric patient serum activates the fetal gene program (FGP). Here we show that serum treatment with Proteinase K prevents activation of the FGP, whereas RNase treatment exacerbates it, suggesting that circulating proteins, but not circulating microRNAs, promote these pathological changes. more...
