Single-cell RNA sequencing data from murine hearts after infarction with endothelial tracing

ABSTRACT: Data set contains samples from isolated cells of murine hearts after myocardial infarction (LAD surgery). We used an endothelial tracing system to mark endothelial cells with EGFP prior to infarct. In brief, Cdh5-ERT2+/-;mT/mG mice, which were used at an age of 10-12 weeks. Cre expression was induced by daily intraperitoneal injections of 2 mg tamoxifen for 1 week in all mice. One week after tamoxifen injection, left anterior descending coronary artery ligation surgery was performed, inducing myocardial infarction. We collected samples at homeostasis, days(d) 1, 3, 7, 14 and 28 after infarction and isolated the non-cardiomyocyte fraction for single cell sequencing. Murine scRNA-seq libraries were prepared using Chromium Single Cell 3′ v3 Reagent Kit (10X Genomics), according to manufacturer’s protocols. Raw reads were mapped against a customized version of mm10 (GRCm38.p4) containing sequences of EGFP and tdTomato.

Single-cell RNA sequencing data from murine hearts after infarction with Collagen-2 tracing

Project description:Data set contains samples from isolated cells of murine hearts after myocardial infarction (LAD surgery). We used Col1a2 tracing system to mark Collagen expressing cells within d3 to d7 post infarct. In brief, adult Col1a2-ERT2+/-;mT/mG mice, at an age of 12 weeks (n=4) as well as aged animals with 88-91 weeks (n=4) were used. Left anterior descending coronary artery ligation surgery was performed, inducing myocardial infarction. Homeostasis animals were not operated. For Cre induction we injected 2mg Tamoxifen from d3 to d7 post surgery. All animals were sacrificed 28d post injury. Murine scRNA-seq libraries were prepared using Chromium Single Cell 3′ v3 Reagent Kit (10X Genomics), according to manufacturer’s protocols. Raw reads were mapped against a customized version of mm10 (GRCm38.p4) containing sequences of EGFP and tdTomato.

Coupled single-cell RNA, TCR, and barcoded pMHC multimer sequencing, from virus-specific PBMC T-cells

Project description:Virus-specific CD8 T cells from PBMCs of healthy donors and hepatitis patients were enriched for recognition of a panel of feature barcode-labeled pMHC multimers. The phenotypic description was made using gene expression and TCRseq. Samples were pooled and sequenced on the same 10x Genomics sequencing chip and deconvoluted using ADT HashTag antibodies,

Effects of Post-Myocardial Infarction Heart Failure on the Bone Vascular Niche (Mouse Data)

Project description:We demonstrate an age-independent loss of type H bone endothelium in heart failure after myocardial infarction in both mice and in humans. Using single-cell RNA sequencing, we delineate the transcriptional heterogeneity of human bone marrow endothelium showing increased expression of inflammatory genes, including IL1B and MYC, in ischemic heart failure. Endothelial-specific overexpression of MYC was sufficient to induce type H bone endothelial cells, whereas inhibition of NLRP3-dependent IL-1 production partially prevents the post-myocardial infarction loss of type H vasculature in mice.

Single cell RNA sequencing of three IDHwt glioblastoma patient tumors

Project description:Single cell RNA sequencing was performed to allow expression-based identification of tumor versus normal cells from glioblastoma patient specimens. Identified tumor cells were then analyzed to assess the expression tumor-cell specific expression of TRIM26, WWP2, and SOX2.

Single nuclei RNA-seq and snATAC-seq multiome performed in WT and Dhx36 conditional KO hearts at postnatal day 7 (PD7)

Project description:In these experiments, we aimed to investigate the role of cardiomyocyte-specific deletion of the G-quadruplex resolvase Dhx36 in heart development and cardiomyocyte differentiation. To achieve this, we conducted multi-omics analysis using single-nuclei RNA sequencing (RNA-seq) and ATAC sequencing (ATAC-seq) on hearts from postnatal day 7 (PD7) wild-type (WT) and Dhx36 conditional knockout (cKO) mice. Our findings reveal that Dhx36 plays a critical role in the development of the cardiac conduction system (CCS) and in the differentiation of both CCS and working cardiomyocytes

Single-cell RNA-seq of mouse cardiac interstitial cells 3 & 7 days after sham or myocardial infarction injury

Project description:The aims of the experiment were to profile the cell types in the adult mouse cardiac interstitium (non-myocyte cells) and how they respond to myocardial infarction injury. Adult, male, Pdgfra +/GFP mice were subject to either a myocardial infarction or sham injury, with cells isolated from cardiac ventricles 3 or 7 days following surgery. We obtained scRNA-seq profiles of two cell fractions: total interstitial (non-myocyte) cell population (TIP) and FACS-sorted GFP+/Cd31- cells (GFP).

Single Nuclei Sequencing of old and young mice hearts under senolytica (Ageing impairs the neuro-vascular interface in the heart)

Project description:Aging is a major risk factor for impaired cardiovascular health. The aging myocardium is characterized by microcirculatory and diastolic dysfunction and increased susceptibility to arrhythmias. Nerves align with vessels during development. However, the impact of aging on the cardiac neuro-vascular interface is entirely unknown. Here, we report that aging reduces nerve density specifically in the left ventricle and dysregulates vascular-derived neuro-regulatory genes. Aging leads to a down-regulation of miR-145 and de-repression of the neuro-repulsive factor Semaphorin-3A. miR-145 deletion, which increased Sema3a expression, or endothelial Sema3a overexpression reduced axon density, thus mimicking the observed aged heart phenotype. Removal of senescent cells, which accumulated with chronological age in parallel to the decline in nerve density, rescued age-induced denervation, reduced Sema3a expression, preserved heart rate variability and reduced electrical instability. These data suggest that senescence-associated regulation of neuro-regulatory genes is associated with reduced nerve density and, thereby, contributes to age-associated cardiac dysfunction.

Bone morphogenic protein-4 availability in the cardiac microenvironment controls myocardial inflammation and fibrosis - Single nucleus RNA sequencing data from healthy and inflamed murine hearts

Project description:Myocarditis is a heart condition that causes inflammation and results in the loss of heart muscle cells, often leading to fibrosis (scarring) of the heart tissue and heart failure. However, the molecular mechanisms underlying immune cell control and maintenance of tissue integrity in the inflamed cardiac microenvironment remain elusive. Based on our finding that bone morphogenic protein-4 (BMP4) serum concentration was reduced in myocarditis patients in combination with comprehensive single cell and single nucleus RNA sequencing analyses of inflamed murine and human myocardial tissue indicated that BMP4 gradients maintain cardiac tissue homeostasis. Indeed, restoration of BMP signaling through antibody-mediated neutralization of the BMP-inhibitors GREM1 and GREM2 reduced CD4+ T cell-mediated myocardial inflammation and blocked disease progression by reduction of adverse fibrotic remodelling. These results unveil a key function of the BMP4-GREM1/2 axis as promising approach for treating myocardial inflammation and the serious complications of cardiac fibrosis and heart failure.
