(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) Regular endurance exercise training induces beneficial functional and health effects in human skeletal muscle. The putative contribution to the training response of the epigenome as a mediator between genes and environment has not been clarified. Here we investigated the contribution of DNA methylation and associated transcriptomic changes in a well-controlled human intervention study. Training effects were mirrored by significant alterations in DNA methylation and gene expression in regions with a homogeneous muscle energetics and remodeling ontology. more...

(Submitter supplied) A total of 23 participants (data available in present submission and in GSE58608) completed three months of supervised aerobic exercise training of one leg. Skeletal muscle biopsies have been collected before and after the training period. We have investigated differences between trained and untrained leg and before and after training by studying the gene and isoform expression. Additional samples present in this study has been previously published (GEO accession number GSE58608).

(Submitter supplied) Skeletal muscle can undergo large transcriptional changes in response to environmental stimuli such as diet or exercise in order to adapt to energetic demands. This remodelling has been associated with changes in muscle DNA methylation potentially regulating gene transcription. Despite abundant evidence that environmental stimuli can alter muscle DNA methylation, the mechanisms by which DNA methylation machinery respond to these stimuli and whether these have a physiological impact is still unclear. more...

(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) The adult skeletal muscle is a plastic tissue with a remarkable ability to adapt to different levels of activity by altering its excitability, its contractile and metabolic phenotype and its mass. Knowledge on the mechanisms responsible for muscle mass comes primarily from models of muscle inactivity or denervation or from genetic models of muscle diseases. Given that the underlying exercise-induced transcriptional mechanisms regulating muscle mass are not fully understood, here we investigated the cellular and molecular adaptive mechanisms taking place in fast skeletal muscle of adult zebrafish in response to swimming. more...

(Submitter supplied) Skeletal muscle tissue demonstrates global hypermethylation with aging. However, methylome changes across the time-course of differentiation in aged human muscle derived cells, and larger coverage arrays in aged muscle tissue have not been undertaken. Using 850K DNA methylation arrays we compared the methylomes of young (27 ± 4.4 years) and aged (83 ± 4 years) human skeletal muscle and that of young/aged heterogenous muscle-derived human primary cells (HDMCs) over several time points of differentiation (0, 72 hours, 7, 10 days). more...

(Submitter supplied) (Abstract of publication submitted currently) To clarify molecular regulation of satellite cells, we performed genome-wide gene expression analysis of quiescent satellite cells isolated from mouse skeletal muscle by flow cytometry. We identified 53 novel quiescent satellite cell-specific genes whose expressions are sharply down-regulated upon activation. The gene list contains a number of cell surface molecules, transcriptional factors, and cytokines and other signal transduction molecules. more...
