Project description:We performed time-series single-cell RNA-seq analysis of blood CD11b+ cells and of the inflammatory infiltrate in the heart of C57BL/6J male mice in a model of permanent myocardial infarction.

Project description:RNA-sequencing of mouse heart post myocardial infarction
Project description:To analyze early transcriptional events in cardiac tissue after infarction and evaluate the genetic expression profile of post-infarction mesenchymal cells of the heart, we induced myocardial infarction in rats by ligation of the left coronary artery. 24 hours after surgery, the affected area was harvested for RNA isolation and cell culture. We then performed a gene expression profile analysis using data obtained from RNA sequencing of 3 different postinfarction tissues and cells. Healthy tissues and cells of the left ventricle of the heart of sham-operated rats were used as controls.
Project description:To define the cellular landscape of human myocardial infarction and heart failure, we performed Cellular Indexing of Transcriptomes and Epitomes by sequencing (CITE-seq) in 22 explanted human hearts from healthy donors, acute myocardial infarction (MI),and chronic ischemic and non-ischemic cardiomyopathy patients.
Project description:Many different cell types constitute the heterogenous group of non-cardiomyocytes (NCM) of the heart. We used single cell RNA sequencing (scRNA-seq) to analyze the diversity of NCM and especially how the absence of TRPM4 affects the inflammatory response post myocardial infarction.
Project description:Myocardial infarction (MI) is a leading cause of heart failure (HF), which is associated with morbidity and mortality worldwide. Understanding the molecular characteristics of of MI is of significance for treating post-MI HF. In this study, RNA-seq was performed on heart tissue from mouse models at multiple time points (sham, 7d and 28d) to explore genetic features that influence MI progression.
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.
