Project description: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.
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.
Project description:The aim of the study was to investigate whether the trefoil peptide genes, in concerted action with a miRNA regulatory network, were contributing to nutritional maintrenance. Using a Tff2 knock-out mouse model, 48 specific miRNAs were noted to be significantly deregulated when compared to the wild type strain.
Project description:The aim of the study was to investigate whether the trefoil peptide genes, in concerted action with a miRNA regulatory network, were contributing to nutritional maintrenance. Using a Tff3 knock-out mouse model, 21 specific miRNAs were noted to be significantly deregulated when compared to the wild type strain.
