(Submitter supplied) Muscle satellite cells are a self-renewing pool of stem cells that give rise to daughter myogenic precursor cells in adult skeletal muscle. Published and preliminary data indicated that MyoD and p53 genes are involved in satellite cell differentiation. We would like to know what downstream genes of both transcription factors are affected in satellite cell-derived myoblasts (MyoD-/-, p53 -/-). Keywords: other

(Submitter supplied) Gene expression changes induced by MyoD or Myf5 were examined in a double-knockout fibroblast cell line lacking endogenous functional myoD or myf5 genes. Use of this cell line precluded the possibility of auto- or cross-activation of endogenous myoD or myf5. Myogenin or hrGFP were expressed in parallel samples as controls. Following infection with retrovirus - expressing the relevant myogenic regulatory factor (MRF) from the viral LTR promoter and hrGFP through an IRES element in the same mRNA transcript - GFP+ cells were sorted by FACS and harvested for total RNA. more...

(Submitter supplied) Pbx homeodomain proteins have been implicated in the regulation of gene expression during muscle development. Whether Pbx proteins are required broadly for the regulation of muscle gene expression or are required for the expression of a specific subset of muscle gene expression is not known. We employed microarrays to determine the requirements for Pbx proteins during zebrafish development. Keywords: developmental time course analysis

(Submitter supplied) In this work we compare the molecular functions of Myf5 and MyoD, two highly related bHLH transcription factors that regulate skeletal muscle specification and differentiation. We find MyoD and Myf5 bind the same sites genome-wide but have distinct functions: Myf5 induces histone acetylation without Pol II recruitment or robust gene activation, whereas MyoD induces histone acetylation, recruits PolII and robustly activates gene transcription.

(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) Ectopic expression of the double homeodomain transcription factor DUX4 causes facioscapulohumeral muscular dystrophy (FSHD). Mechanisms of action of DUX4 are currently unknown. Using immortalized human myoblasts with a titratable DUX4 transgene, we identify by mass spectrometry an interaction between the DUX4 C-terminus and the histone acetyltransferases p300/CBP. Chromatin immunoprecipitation shows that DUX4 recruits p300 to its target gene, ZSCAN4, displaces histone H3 from the center of its binding site, and induces H3K27Ac in its vicinity, but C-terminal deleted DUX4 does not. more...

(Submitter supplied) We used a combination of genome-wide and promoter-specific DNA binding and expression analyses to assess the functional roles of Myod and Myog in regulating the program of skeletal muscle gene expression. Our findings indicate that Myod and Myog have distinct regulatory roles at a similar set of target genes. At genes expressed throughout the program of myogenic differentiation, Myod can bind and recruit histone acetyltransferases. more...

(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) Rhabdomyosarcomas (RMS) are characterized by expression of myogenic specification genes, such as MyoD and/or Myf5, as well as their bHLH partners for heterodimerization, the E-proteins. We have shown that expression of a forced heterodimer of MyoD with one of the E2A proteins, E12, leads to differentiation in a RMS cell culture model when exposed to low serum conditions.

(Submitter supplied) The molecular determinants of muscle progenitor impairment to regenerate aged muscles are currently unclear. We show that in a mouse model of replicative senescence, decline in muscle satellite cell-mediated regeneration coincides with activation of DNA damage response (DDR) and impaired ability to differentiate into myotubes. Inhibition of DDR restored satellite cell differentiation ability. Moreover, in replicative human senescentfibroblasts DDR precluded MYOD-mediated activation of the myogenic program. more...

(Submitter supplied) Increasing evidence suggests that Long non-coding RNAs (LncRNAs) represent a new class of regulators of stem cells. However, the roles of LncRNAs in stem cell maintenance and myogenesis remain largely unexamined. For this study, hundreds of novel intergenic LncRNAs were identified that are expressed in myoblasts and regulated during differentiation. One of these LncRNAs, termed LncMyoD, is encoded next to the Myod gene and is directly activated by MyoD during myoblast 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...
