Project description:Recent studies in non-human model systems have shown therapeutic potential of modified mRNA (modRNA) treatments for lysosomal storage diseases. Here, we assessed the efficacy of a modRNA treatment to restore the expression of the α-galactosidase (GLA) gene in a human cardiac model generated from induced-pluripotent stem cell-derived from two patients with Fabry disease. In line with the clinical phenotype, cardiomyocytes from Fabry patient’s induced pluripotent stem cells show accumulation of the glycosphinolipid Globotriaosylceramide (GB3), which is an α-galactosidase substrate. Further, the patient-specific cardiomyocytes have significant upregulation of lysosomal associated proteins. Upon modRNA treatment, a subset of lysosomal proteins were partially restored to wildtype levels, implying the rescue of the molecular phenotype associated with the Fabry genotype. Importantly, a significant reduction of GB3 levels was observed in GLA modRNA treated cardiomyocytes demonstrating that α-galactosidase enzymatic activity was restored. Together, our results validate the utility of patient IPSC-derived cardiomyocytes as a model to study disease processes in Fabry disease and the therapeutic potential of GLA modRNA treatment to reduce GB3 accumulation in the heart.

Project description:To gain insight into the molecular regulation of human heart development, a detailed comparison of the mRNA and miRNA transcriptomes across differentiating human-induced pluripotent stem cell (hiPSC)–derived cardiomyocytes and biopsies from fetal, adult, and hypertensive human hearts was performed. Gene ontology analysis of the mRNA expression levels of the hiPSCs differentiating into cardiomyocytes revealed 3 distinct groups of genes: pluripotent specific, transitional cardiac specification, and mature cardiomyocyte specific. Hierarchical clustering of the mRNA data revealed that the transcriptome of hiPSC cardiomyocytes largely stabilizes 20 days after initiation of differentiation. Nevertheless, analysis of cells continuously cultured for 120 days indicated that the cardiomyocytes continued to mature toward a more adult-like gene expression pattern. Analysis of cardiomyocyte-specific miRNAs (miR-1, miR-133a/b, and miR-208a/b) revealed a miRNA pattern indicative of stem cell to cardiomyocyte specification. A biostatistitical approach integrated the miRNA and mRNA expression profiles revealing a cardiomyocyte differentiation miRNA network and identified putative mRNAs targeted by multiple miRNAs. Together, these data reveal the miRNA network in human heart development and support the notion that overlapping miRNA networks re-enforce transcriptional control during developmental specification.

Project description:Pluripotent stem cells are defined by their self-renewal capacity, which is the ability of the stem cells to proliferate indefinitely while maintaining the pluripotent identity essential for their ability to differentiate into any somatic cell lineage. However, understanding the mechanisms that control stem cell fitness versus the pluripotent cell identity is challenging. To investigate the interplay between these two aspects of pluripotency, we performed four parallel genome-scale CRISPR-Cas9 loss-of-function screens interrogating stem cell fitness in hPSC self-renewal conditions, and the dissolution of the primed pluripotency identity during early differentiation. Comparative analyses led to the discovery of genes with distinct roles in pluripotency regulation, including mitochondrial and metabolism regulators crucial for stem cell fitness, and chromatin regulators that control pluripotent identity during early differentiation. We further discovered a core set of factors that control both stem cell fitness and pluripotent identity, including a network of chromatin factors that safeguard pluripotency. Our unbiased and systematic screening and comparative analyses disentangle two interconnected aspects of pluripotency, provide rich datasets for exploring pluripotent cell identity versus cell fitness, and offer a valuable model for categorizing gene function in broad biological contexts.

Project description:To define molecular markers of tyrosine kinase inhibitor-induced cardiotoxicity, we measured transcriptome changes in human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) treated with one of four tyrosine kinase inhibitors (Erlotinib, Lapatinib, Sorafenib, or Sunitinib) displaying a range of mild to severe cardiotoxicity or a vehicle-only control (DMSO). Gene expression changes were assessed at the cell population level using total RNA-seq, which measured levels of both mRNAs and non-coding RNAs. hiPSC-CMs used in this study were the Cor.4U cells purchased from Ncardia.
