Impact of myeloid cell specific deletion of EGFR on cardiac Cd11b+ non-myocyte gene expression

ABSTRACT: Epidermal Growth Factor Receptor (EGFR) is a critical factor regulating numerous aspects of cell biology. Though it is widely recognized as an oncogene, EGFR has been implicated in cardiovascular health, and has been shown to have unique cell specific roles in the heart. Macrophages and other myeloid cells play key roles in normal cardiac physiology and post injury pathological outcomes. Myeloid cell EGFR has been implicated in disease, though its role in the normal or failing heart has yet to be established. Here, we crossed EGFR floxed mice with LysM Cre transgenics to specifically delete EGFR in Cd11b+ myeloid cells. We then isolated non-cardiomyocytes and subject them to Cd11b microbeads and subsequent column concentration to obtain cardiac Cd11b+ non-myocyte myeloid cells. We used samples from floxed EGFR controls, and EGFR specific myeloid knockouts. In comparisson to control, myeloid EGFR knockouts had 763 differential transcripts when consdering p adjusted less than 0.05 and log2foldchange greater than absolute value 1.5.

Gene expression in the embryonic Lrrc10 knockout heart

Project description:LRRC10 is a heart-specific gene required for proper cardiac function. The effects of Lrrc10 deletion on gene expression in the embryonic mouse heart was investigated. Pregnant heterozygous Lrrc10 knockout mice (Lrrc10+/-) mated to male heterozygous knockouts (Lrrc10+/-), housed in 12 hour light:12 dark, ad lib feeding and drinking conditions, were sacrificed at embryonic day 15.5 (E15.5) and embryonic hearts were dissected for cardiac gene expression analysis. A two color, reference design experiment in which heart RNA from 2 Lrrc10 homozygous knockout embryos (Lrrc10-/-) were pooled and labeled with Cy5 and hybridized according to Agilent protocols against a reference pool of RNA madeup from respective tissue taken from littermate E15.5 wildtype (Lrrc10+/+) hearts and labeled with Cy3.

Cellular plasticity and diversity during heart valve epithelial-to-mesenchymal transitions revealed using single-cell RNA-seq

Project description:We have generated scRNA-seq data from embryonic day (E)10.5 and E12.5 atrioventricular canals (primitive heart valves) to assess cellular diversity during the distinct epithelial-to-mesenchymal transitions (EMTs) from endocardium and epicardium that guide the formation of valve mesenchyme. Alongside, wildtype atrioventricular canals, we generated scRNA-seq data from Sox9 conditional knockouts (Sox9fl/fl;Tie2-cre) to explore the role of SOX9 in EMT. Atrioventricular canals were microdissected from cardiac chambers and outflow tract, enriching for heart valve progenitor lineages.

Muscleblind-like compound knockout models for myotonic dystrophy

Project description:Myotonic dystrophy (DM) is a multi-systemic disease that severely impacts cardiac and skeletal muscle functions as well as the central nervous system. DM is unusual because it is RNA-mediated disease due to the expression of C(C)UG expansion RNAs that inhibit the activities of the muscleblind-like (MBNL) proteins. In mice, studies using Mbnl1 and Mbnl2 single knockouts have revealed that Mbnl1 plays a predominant role in skeletal and heart muscle alternative splicing regulation while Mbnl2 performs an analogous splicing function in the brain. However, Mbnl single knockout models fail to recapitulate the full-range of adult-onset DM muscle symptoms. Here, we report that Mbnl1; Mbnl2 double knockouts are embryonic lethal while Mbnl1-/-; Mbnl2+/- mice, which express no Mbnl1 and reduced levels of Mbnl2, are viable but develop cardinal features of adult-onset DM cardiac and skeletal muscle disease including reduced lifespan, heart conduction block, severe myotonia and progressive skeletal muscle weakness. Mbnl2 protein levels are elevated in both Mbnl1-/- and Mbnl1-/-; Mbnl2+/- knockouts where Mbnl2 targets Mbnl1-regulated exons. These findings support the MBNL loss-of-function model for DM and provide novel Mbnl compound knockout models to investigate the molecular pathways disrupted by RNA-mediated disease. Mbnl2 protein-RNA interactions were assessed in 4-month-old WT and Mbnl1-/- quadriceps muscles in triplicates by HITS-CLIP.

Transcription profiling of mouse Fog2flox/delta; MHCaCre vs. Fog2flox/deltaFog2 to investigate Fog2 regulation of gene expression in the adult heart

Project description:MHCaCre induced knockout of Fog2flox. Aberrant transcriptional regulation contributes to the pathogenesis of both congenital and adult forms of heart disease. While the transcriptional regulator FOG2 is known to be essential for heart morphogenesis and coronary development, its tissue specific function has not been previously investigated. Additionally, little is known about the role of FOG2 in the adult heart. Here we use spatiotemporally regulated inactivation of Fog2 to delineate its function both in embryo and adult heart. Early cardiomyocyte-restricted loss of Fog2 recapitulated the cardiac and coronary defects of the Fog2 germline knockouts. Later cardiomyocyte-restricted loss of Fog2 (Fog2MC) did not result in defects in cardiac structure or coronary vessel formation. However, Fog2MC adult mice had severely depressed ventricular function and died at 8-14 weeks. Fog2MC adult hearts displayed a paucity of coronary vessels. This was associated with myocardial hypoxia, increased cardiomyocyte apoptosis, and cardiac fibrosis. Induced inactivation of Fog2 in adult heart resulted in similar phenotype, as did ablation of FOG2 interaction with the transcription factor GATA4. Loss of FOG2 or FOG2-GATA4 interaction altered expression of a panel of angiogenesis-related genes. Collectively, our data indicated that FOG2 regulates adult heart function and coronary angiogenesis. Experiment Overall Design: Fog2flox/delta; MHCaCre (3) compared to Fog2flox/delta; no Cre (3). One heart per sample.

RNA-Sequencing of heart tissue obtained from cardiac specific-Dsg2-/- and wild-type (Dsg2+/+) mice at 2-weeks and 10-weeks of age

Project description:We studied how loss of the desmosome associated protein, desmoglein-2 (Dsg2), in the heart leads to Arrhythmogenic Cardiomyopathy with particular interest in the early stages of disease progression. Mice expressing the cardiac αMHC-Cre promoter were crossed with Dsg2 floxed mice in which exon 4-5 of the Dsg2 gene was flanked by loxP sites, resulting in Cre-mediated excision of Dsg2 in cardiac myocytes. Wild type Dsg2+/+ (Cre-, Dsg2flx/flx) and knockout Dsg2-/- (Cre+, Dsg2flx/flx) mice were generated. RNA-seq was performed on heart tissue obtained from wild-type and Dsg2-/- mice at 2-weeks and 10-weeks of age.

Transcriptome profiling of control and Zmynd8-cKO mouse cardiomyocyte

Project description:Appropriate gene expression within cardiomyocytes is coordinated by chromatin factors and is essential for heart function. We investigated the role of the chromatin reader ZMYND8 in the mouse heart using null and conditional knockouts (Zmynd8-cKO). While full-length Zmynd8 is not required for cardiomyocyte development, Zmynd8-cKO mice develop cardiomegaly, decreased cardiac function, and premature death compared to controls. Transcriptome analysis of Zmynd8-cKO cardiomyocytes reveals illegitimate expression of transcripts and proteins normally limited to skeletal muscle and integration of TNNI2 skeletal troponin into cardiac sarcomeres of mutant mice. We conclude that ZMYND8 is necessary to maintain appropriate cardiomyocyte homeostasis and gene expression.

Global gene expression profiling of cardiac dendritic cells subsets

Project description:Innate and adaptive immune cells modulate heart failure pathogenesis during viral myocarditis, yet their identity and functions remain poorly defined. In this study we characterized the phenotype, life-cycle and function of different conventional dendritic cells (cDC) populations in the heart, with focus on the 2 major subsets (CD103+ and CD11b+), which differentially rely on local proliferation and precursor recruitment to maintain tissue residency. Following viral infection of the myocardium, cDCs accumulate in the heart coincident with monocyte infiltration and loss of resident reparative embryonic-derived cardiac macrophages. cDC depletion abrogates antigen-specific CD8+ T cell proliferative expansion, transforming subclinical cardiac injury to overt heart failure. Importantly, these effects are mediated by BATF3-dependent CD103+ cDCs. Collectively, our findings definitively identify resident cardiac cDC subsets, define their origins, and implicate an essential role for CD103+ cDCs in antigen-specific T cell responses during viral myocarditis.
