(Submitter supplied) Satellite cells are myogenic precursor cells in adult skeletal muscle and play a crucial role in skeletal muscle repair, remodeling, and maintenance. Like myoblasts, satellite cells have the ability to proliferate, differentiate, and fuse to form multinucleated myofibers. In this study we aimed to identify the enhancers and the transcription factors binding to these enhancers that control gene expression in proliferating and differentiating bovine satellite cells. more...

(Submitter supplied) In this study we isolated satellite cells from skeletal muscle from two Angus-crossbred steers, initially cultured them in growth medium for proliferation, and then in differentiation medium to induce them to differentiate and fuse into myotubes. We used ChIP-seq to identify enhancers marked with H3K27ac, i.e., active enhancers, from these cells immediately before and two days after induction of differentiation. more...

(Submitter supplied) Skeletal muscle differentiation (myogenesis) is a complex and highly coordinated biological process regulated by a series of myogenic marker genes. Chromatin interactions between gene’s promoters and their enhancers have an important role in transcriptional control. However, the high-resolution chromatin interactions of myogenic genes and their functional enhancers during myogenesis remain largely unclear. more...

(Submitter supplied) The acquisition of a proliferating cell status from a quiescent state as well as the shift between proliferation and differentiation are key developmental steps in skeletal-muscle stem cells (satellite cells) to provide proper muscle regeneration. However, how satellite-cell proliferation is regulated, though, is not fully understood. Here, we report that the c-isoform of the transcription factor Pitx2 increases cell proliferation in myoblasts by down-regulating the miRNAs miR-15b, miR-23b, miR-106b, and miR-503. more...

(Submitter supplied) Cellular differentiation involves widespread epigenetic reprogramming, including modulation of DNA methylation patterns. We have investigated DNA genome-wide methylation dynamics in embryonic stem cells, primary myoblasts, terminal differentiated myotubes and mature myofibers. About 1.000 differentially methylated regions (DMRs) have been indentified during muscle-lineage determination and terminal differentiation. more...

(Submitter supplied) We performed ATAC-seq for microdissected lens epithelium and fiber from E14.5 and P0.5 mouse lenses.Through investigating dynamics of chromatin changes during mouse lens fiber and epithelium differentiation, we identified spatial-temporal differential accessible regions and the enriched known and novel motifs. We also discovered some novel and known enhancers for the transcription factors and structural genes that are important in lens development. more...

(Submitter supplied) Defining the function of TEAD transcription factors in myogenic differentiation has proved elusive due to overlapping expression and functional redundancy. Here, we show that siRNA silencing of either Tead1, Tead2 or Tead4 did not effect differentiation of primary myoblasts (PMs) while their simultaneous knockdown strongly impaired differentiation. In contrast in C2C12 cells, silencing of Tead1 or Tead4 impaired differentiation showing a differential requirement for these factors in PMs and C2C12 cells that involved both differential regulation of their expression and intracellular localisation. more...

(Submitter supplied) Skeletal muscle contains long multinucleated and contractile structures known as muscle fibers, which arise from the fusion of myoblasts into nucleated myotubes during myogenesis. The myogenic regulatory factor (MRF) MYF5 is the earliest to be expressed during myogenesis and functions as a transcription factor in muscle progenitor cells (satellite cells) and myocytes. In mouse C2C12 myocytes, MYF5 is implicated in the initial steps of myoblast differentiation into myotubes. more...

(Submitter supplied) Molecular regulation of stem cell differentiation is exerted through both genetic and epigenetic determinants over distal regulatory or enhancer regions. Understanding the mechanistic action of active or poised enhancers is thus imperative for control of stem cell differentiation. Based on a genome-wide co-occurrence of different epigenetic marks in committed proliferating myoblasts, we have previously generated a 14-state chromatin state model to profile residue-specific histone acetylation in early myoblast differentiation. more...

(Submitter supplied) Deletion of Klf5 in satellite cells impaired muscle regeneration due to a failure of differentiation. Mechanistically, Klf5 controls transcription of muscle genes by interacting with MyoD and Mef2. These findings provide a potential intervention into the process of muscle regeneration through modulation of Klf5.

(Submitter supplied) In this study we analyzed the bovine satellite cells with single-cell RNA sequencing (scRNA-seq). We isolated muscle satellite cells from a male calf, cultured them in growth medium for a week, and then constructed two scRNA-seq libraries from them using the 10x Genomics platform. Next generation sequencing yielded 860 million reads. Cell calling analyses revealed that these reads represented 15 cell clusters that differed in gene expression profile from a total of 19,096 individual cells.

(Submitter supplied) The trithorax H3K4 histone methyltransferase (HMT) MLL1 has important roles for early embryonic development, hematopoiesis and neurogenesis through regulation of Hox and homeodomain factor expression. MLL1 has been previously implicated in activation of Myf5 expression through an interaction with Pax7. Here, we find that in vivo, MLL1 is necessary for efficient muscle regeneration, and for maintenance of muscle stem and progenitor cells. more...

(Submitter supplied) Muscle stem cells, also known as satellite cells, represent the main myogenic population accounting for skeletal muscle homeostasis and regeneration. Here, using the Assay for Transposase Accessible Chromatin followed by sequencing (ATAC-seq), we investigated the epigenetic landscape of activated human and murine satellite cells. Our analysis identified a compendium of putative regulatory elements defining activated satellite cells and myoblasts, respectively.
