(Submitter supplied) DNA methylation has been considered to play an important role in myogenic differentiation. In terminal differentiation of myoblasts, a chronological pattern of DNA methylation changes has been poorly understood. Using Infinium HumanMethylation450 BeadChips, we obtained and evaluated the genome-wide DNA methylation profiles of human myoblast differentiation in vitro.

(Submitter supplied) DNA methylation has been considered to play an important role during myogenic differentiation. In terminal differentiation of myoblasts, chronological alteration of DNA methylation status was poorly understood. Using Infinium HumanMethylation450 BeadChips, we validated genome wide DNA methylation profiles of human myoblast differentiation models. To investigate correlation between DNA methylation and gene expression, we also assessed gene expression of myoblasts with GeneChip Human Genome U133 Plus 2.0 array.

(Submitter supplied) We identify a subset of highly expressed genes related to muscle development, which show static H3K4me2 enrichment over the gene body and H3K4me3 enrichment towards the gene body during myogenic differentiation. This study reveals that MyoD significantly binds to this particular subset of genes and further systematic analysis shows the repressive role of MyoD. Interestingly, MyoD binds and down-regulates Patz1 which is important for maintaining pluripotency. more...

(Submitter supplied) Here we describe a genome-wide analysis of DNA-methylation in muscle of trained mice. In comparison to sedentary controls 2762 genes exhibited differentially methylated CpGs in their putative promoter regions. The majority of these genes were related to muscle growth and differentiation and a minor fraction involved in metabolic regulation. These findings suggest that DNA-methylation is involved in the regulation of muscle adaptation to regular exercise training.

(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) Rhabdomyosarcoma is a pediatric tumor of skeletal muscle that expresses the myogenic basic helix-loop-helix protein MyoD but fails to undergo terminal differentiation. Prior work has determined that DNA binding by MyoD occurs in the tumor cells, but myogenic targets fail to activate. Using MyoD chromatin immunoprecipitation coupled to high-throughput sequencing and gene expression analysis in both primary human muscle cells and RD rhabdomyosarcoma cells, we demonstrate that MyoD binds in a similar genome-wide pattern in both tumor and normal cells but binds poorly at a subset of myogenic genes that fail to activate in the tumor cells. more...

(Submitter supplied) miRNA profiling of bovine satellite cells (BSC) differentiated into myotubes (6th day of in vitro differentiation). BSC isolated from m. semitendinosus of beef (Hereford & Limousine) and dairy (Holstein-Friesian) cattle. Goal was to determine differences in miRNA expresion during in vitro myogenesis in beef vs dairy cattle used as a control.

(Submitter supplied) Differentiation of pluripotent embryonic stem cells, via more restricted multipotent adult stem cells, towards the multitude of terminally differentiated, specialized cell types that make up the adult body is a multi-step process characterized by a progressive restriction of differentiation potential. Previous studies have demonstrated tissue-specific differences in DNA methylation patterns that might play a role in lineage restriction and tissue-specific gene expression. more...

Chromatin regions with different transcriptional outputs are distinguished by the deposition of histone variants.

ZEB2 is a two-handed zinc-finger closely related to ZEB1 (ZFHX1a/δEF1) and it is present in many tissues including cardiac and skeletal muscles. Skeletal muscle development and adult myogenesis are regulated by helix-loop-helix proteins, including MyoD, Myf5, myogenin and MRF-4. more...
