Project description:Analysis of the transcriptome of zebrafish mononuclear myogenic cells (zMNCs) during myogenic differentiation. The main goal is to identify the similarities of zMNC myogenic differentiation with that of mammalian myoblast differentiation. Critical time points were used to identify a switch from the activity of cell proliferation genes to myogenic structural genes. 15-20 adult zebrafish dorsal skeletal muscles were isolated at each of 6 distinct time points (day 0, day 1, day 4, day 7, day 10, day 14) in replicates.

Project description:Rhabdomyosarcoma (RMS) is a frequent non-epithelial tumor of soft tissue that originates from a myogenic differentiation defect. Expression of SNAIL transcription factor is elevated in the alveolar subtype of RMS, characterized by a low myogenic differentiation status and high aggressiveness. SNAIL affects RMS metastasis by reorganization of actin cytoskeleton, regulation of ezrin expression and chemotaxis to HGF and SDF-1. The differentiation of human RMS diminishes SNAIL level. SNAIL silencing completely abolishes the growth of human RMS xenotransplants. SNAIL inhibits myogenic differentiation of RMS by binding to the MYF5 promoter, suppressing its expression, displacing MYOD from canonical to alternative E-box sequences and regulating myomiRs expression. SNAIL silencing allows the re-expression of MYF5 and canonical MYOD binding, promoting RMS cell myogenic differentiation. These novel results open potential avenues for the development of innovative therapeutic strategies based on SNAIL silencing.

Project description:Identifying tissue and condition-specific gene regulatory elements and the mechanisms by which they associate with their target genes in human cells remains a significant challenge, largely due to the vast amount of non-protein-coding sequence in the human genome. Despite increasing evidence of physical interactions between distant regulatory regions and gene promoters in a variety of mammalian cell types, many searches for regulatory regions still consider only genomic regions proximal to the gene promoter. We identify a set of putative cis-regulatory modules (CRMs) of human skeletal muscle differentiation by combining new ChIP-chip data measuring the binding of myogenic TFs MyoG, MyoD, and SRF over the timecourse of differentiation with previously generated histone modification data. A substantial proportion of these putative CRMs are located distant (> 20 kb) from muscle gene promoters, and these distantly located CRMs are more likely than proximal promoter regions to show differentiation-specific changes in myogenic TF binding. Examination of two distant CRMs, which were previously shown to activate transcription in differentiating muscle cells, revealed that they interact physically with their upstream or downstream gene promoters (PDLIM3 and ACTA1) specifically upon myogenic differentiation. Our results highlight the importance of considering CRMs located distant from their target genes in investigations of mammalian gene regulation and further support the hypothesis that enhancer-promoter looping contacts are a general mechanism of regulation by distant CRMs.

Project description:Purpose: Cyclic mechanical stretch (CMS) promoted proliferation of serum starved mesenchymal stem cells (MSCs) by inhibiting miR-337 expression, similar to FBS. In order to reveal the underlying mechanisms of both CMS and FBS on MSC activation, as well as the regulatory role of miR-337, this research performed high-throughput RNA sequencing (RNA-seq) on MSCs isolated from both wild-type (ET)- and miR-337 knockout- (miR-337-/-) rats. Methods: MSCs isolated form 2-month-old wild-type (WT) and miR-337 knockout (-/-) rats and cultured in vitro to passage 3. After serum starvation for 8h, MSCs were treated with FBS or 10% CMS for another 24h before deep sequencing in triplicate, using Illumina GAIIx. The sequence reads that passed quality filters were analyzed at the transcript isoform level. Results: Using an optimized data analysis workflow, we mapped about 40 million sequence reads per sample. We identified 2472 differentially expressed genes (DEGs) between CMS-stimulated vs. SSt conditions, 2468 DEGs FBS-treated vs. SSt groups. However, only 97 DEGs were identified between CMS and FBS groups, indicating that CMS and FBS groups are more similar to each other and both CMS and FBS groups are quite different from the SSt group. Analysis of DEGs between CMS- or FBS-treated and SSt -treated group revealed that CMS and FBS stimulation activated similar biological processes, of which, PI3K-Akt-mTOR pathway was highly enriched. However, PI3K-Akt-mTOR pathway was not enriched in miR-337-/- MSCs, indicating constitutive activation of this pathway. Conclusions: Our RNA-seq data revealed that both CMS and FBS activates quiescent MSCs through regulating similar genes and pathways. miR-337 is one of the main factors that regulate MSC activation by targeting PI3K-Akt pathway.

Biological and technical replicates of ChIP-chip experiments were performed using antibodies for MyoG and SRF in primary human skeletal muscle myoblasts crosslinked at 0 and 48 h relative to the removal of serum to induce differentiation. Additional technical replicate ChIP-chip experiments were performed for MyoD at 0 and 48 hours post-differentiation and p300 at 48 h post-differentiation. Total Input DNA for each experiment was labeled with Cy3 and used to create log-ratios with the Cy5 labeled IP data. Negative control no antibody mock-IP ChIP experiments were performed at 0 and 48 h post-differentiation.
