SARS-CoV-2 Infection Induces Ferroptosis of Human Pluripotent Stem Cell-Derived Sinoatrial Nodal like Pacemaker Cells [single-cell RNA-seq]

ABSTRACT: We established an efficient strategy to derive functional human SAN like pacemaker cells for disease modeling and drug screening. We used a dual-reporter cell line(SHOX2-GFP+MYH6-mcherry) to indicate the sinoatrial nodal like pacemaker cells. We sorted out the double positive cell population after Day20 and prepared the sample for single cell RNA seq analysis.

Single-cell transcriptome analysis reveals CD34 as a marker of human sinoatrial node pacemaker cardiomyocytes [hPSC_SAN]

Project description:The sinoatrial node regulates the heart rate throughout life. Failure of this primary pacemaker results in life-threatening, slow heart rhythm. Despite its important function, the cellular and molecular composition of the human sinoatrial node is not resolved. Particularly, no cell surface marker to identify and isolate sinoatrial node pacemaker cells has been reported. Here we use single-nuclei/cell RNA sequencing of fetal and human pluripotent stem cell-derived sinoatrial node cells and show that they consist of three subtypes of pacemaker cells, including Core Pacemaker, Sinus Venosus, and Transitional Cells. Our study identifies a host of sinoatrial node pacemaker markers including MYH11, BMP4, and the cell surface antigen CD34. We demonstrate that sorting for CD34+ cells from stem cell differentiation cultures enriches for sinoatrial node cells with a functional pacemaker phenotype. This sinoatrial node pacemaker cell surface marker is highly valuable for stem cell-based disease modelling, drug discovery, cell replacement therapies, as well as the delivery of therapeutics to sinoatrial node cells in vivo using antibody-drug conjugates.

Pharmacogenetics and Drug Discovery for Anthracycline-Induced Cardiotoxicity Enabled by Sinoatrial Node-like Cells Derived from Human Pluripotent Stem Cells [SNP array]

Project description:The sinoatrial node (SAN) is the primary pacemaker of the heart. The human SAN is poorly understood due to limited primary tissue access and lack of robust in vitro derivation methods. We developed an efficient strategy, using a dual SHOX2:GFP; MYH6:mCherry knock-in reporter line, to generate and purify human pluripotent stem cell-derived SAN cells (hPSC-SAN), displaying molecular and electrophysiological characteristics of bona-fide nodal cells. We modeled cell type specific toxicity upon treatment with doxorubicin (DOXO) using hPSC-SAN generated from a library of induced pluripotent stem cells (iPSCs). We discovered 3 new genetic loci associated with increased sensitivity to DOXO-induced hPSC-SAN death. Genetic variants in these loci were associated with significantly higher early arrhythmia risk in patients receiving DOXO, confirmed by an unbiased PheWAS analysis. Finally, the in vitro DOXO assay enabled an unbiased drug screening platform and identification of physcion as a candidate therapeutic that can partially block DOXO-mediated cardiac toxicity.

SARS-CoV-2 Infection Induces Ferroptosis of Human Pluripotent Stem Cell-Derived Sinoatrial Nodal like Pacemaker Cells [bulk RNA-seq]

Project description:We established an efficient strategy to derive functional human SAN like pacemaker cells for disease modeling and drug screening. And we found SARS-CoV-2 infection causes dysfunction of human SAN like pacemaker cells and induces ferroptosis. And we also found that Deferoxamine and imatinib can block SARS-CoV-2 infection and infection-associated ferroptosis. Our study using functional human SAN like pacemaker cells demonstrates a potential mechanism for some COVID-19 cardiac abnormalities and identifies candidate drugs to protect the SAN like pacemaker from SARS-CoV-2 infection.

Mouse sinoatrial node transcriptome

Project description:RNA Sequencing of Mouse Sinoatrial Node Reveals an Upstream Regulatory Role for Islet-1 in Cardiac Pacemaker Cells Rationale: Treatment of sinus node disease with regenerative or cell-based therapies will require a detailed understanding of gene regulatory networks in cardiac pacemaker cells (PCs). Objective: To characterize the transcriptome of PCs using RNA sequencing, and to identify transcriptional networks responsible for PC gene expression. Methods and Results: We used laser capture micro-dissection (LCM) on a sinus node reporter mouse line to isolate RNA from PCs for RNA sequencing (RNA-Seq). Differential expression and network analysis identified novel SAN-enriched genes, and predicted that the transcription factor Islet-1 (Isl1) is active in developing pacemaker cells. RNA-Seq on SAN tissue lacking Isl1 established that Isl1 is an important transcriptional regulator within the developing SAN. Conclusions: (1) The PC transcriptome diverges sharply from other cardiomyocytes; (2) Isl1 is a positive transcriptional regulator of the PC gene expression program. There are 25 RNA-Sequencing Samples
