Project description:GATA4 occupancy on the mouse genome of satellite cell-derived primary myoblasts. Proliferating myoblasts cultured in growth medium were immunoprecipitated with anti-GATA4 antibody or control IgG. Precipitated genomic DNAs were subjected to next generation sequencing. Paired-end 150 bp sequence reads of GATA4-ChIP and IgG-ChIP using mouse skeletal muscle myoblasts.

Project description:Identfification of MEF2A target genes using ChIP-exo in skeletla muscle and primary cardiomyocytes. Identfification of MEF2A target genes using ChIP-exo and RNA-seq in skeletal muscle and primary cardiomyocytes. MEF2 plays a profound role in the regulation of transcription in cardiac and skeletal muscle lineages. To define the overlapping and unique MEF2A genomic targets, we utilized ChIP-exo analysis of cardiomyocytes and skeletal myoblasts. Of the 2783 and 1648 MEF2A binding peaks in skeletal myoblasts and cardiomyocytes, respectively, 294 common binding sites were identified. Genomic targets were compared to differentially expressed genes in RNA-seq analysis of MEF2A depleted myogenic cells. MEF2A target genes were identified in 48 hr DM C2C12 myoblasts cells and primary cardiomyocytes using ChIP-exo. Binding profiles on MEF2A in each cell type were compared. Cross sectional-analysis between ChIP-exo identified targets and RNA-seq analysis of MEF2A deplted myoblasts was also done.

The effect of MEF2A gene silencing on gene expression in myoblasts was assessed at 48 hr DM. Up and downregulated genes were then compared to MEF2A target genes identified in ChIP-exo analysis of 48 hr DM C2C12 myoblasts cells and primary cardiomyocytes.

Project description:The histone 3 lysine 9 (H3K9)-specific methyltransferase (KMT) Setdb1 is essential for both stem cell pluripotency and terminal differentiation of different cell types. To shed light on Setdb1 role(s) in these mutually exclusive processes, we used mouse skeletal myoblasts as a model of terminal differentiation. Ex vivo studies on isolated single myofibres showed that Setdb1 is required for muscle adult stem cells expansion following activation and in vitro studies on skeletal myoblasts confirmed that Setdb1 suppresses terminal myoblast differentiation. We used genome-wide analyses to identify Setdb1 direct target genes in myoblasts and observed a release of Setdb1 from the promoter of selected target genes upon myoblast terminal differentiation, concomitant to a nuclear export of Setdb1 to the cytoplasm. We demonstrated that both genomic release and cytoplasmic Setdb1 relocalisation during differentiation were dependent on canonical Wnt signalling. Taken together, our findings uncover a functional link between Setdb1 and canonical Wnt signalling in skeletal muscle cells, which affects the expression of a subset of Setdb1 target genes. We revealed Wnt-dependent subcellular relocalisation of Setdb1 as a novel mechanism regulating Setdb1 functions. ChIP-seq of Setdb1 and H3K9me3 in Myoblast cells (C2C12)
