(Submitter supplied) In skeletal myogenesis, the transcription factor MyoD activates distinct transcriptional programs in progenitors compared to terminally differentiated cells. Using ChIP-seq and gene expression analyses, we show that in primary myoblasts, Snail-HDAC1/2 repressive complex bind and exclude MyoD from its targets. Notably, Snail binds E-box motifs that are G/C-rich in their central dinucleotides, and such sites are almost exclusively associated with genes expressed during differentiation. more...

(Submitter supplied) Super-enhancers (SEs) are cis-regulatory elements enriching lineage specific key transcription factors (TFs) to form hotspots. A paucity of identification and functional dissection promoted us to investigate SEs during myoblast differentiation. ChIP-seq analysis of histone marks leads to the uncovering of SEs which remodel progressively during the course of differentiation. Further analyses of TF ChIP-seq enable the definition of SE hotspots co-bound by the master TF, MyoD and other TFs, among which we perform in-depth dissection for MyoD/FoxO3 interaction in driving the hotspots formation and SE activation.

(Submitter supplied) The transcriptional activator MyoD serves as a master controller of myogenesis. Often in partnership with Mef2, MyoD binds to the promoters of hundreds of muscle genes in proliferating myoblasts, yet activates these targets only upon receiving cues that launch differentiation. What regulates this off/on switch of MyoD function has been incompletely understood, although known to reflect the action of chromatin modifiers. more...

(Submitter supplied) MyoD and NeuroD2 are master regulators of myogenesis and neurogenesis and bind to a "shared" E-box sequence (CAGCTG) and a "private" sequence (CAGGTG or CAGATG, respectively). To determine whether private-site recognition is sufficient to confer lineage-specification, we generated a MyoD-mutant with the DNA binding specificity of NeuroD2. Our results demonstrate that redirecting MyoD binding from MyoD-private sites to NeuroD2-private sites, despite preserved binding to the MyoD/NeuroD2-shared sites, is sufficient to change MyoD from a master regulator of myogenesis to a master regulator of neurogenesis.

(Submitter supplied) The cis-regulatory code is the cellular lexicon by which the transcriptional machinery converts sequence information within cis-regulatory modules (CRMs) into gene expression output. Tissue-specific transcription factors such as MyoD orchestrate gene expression programs by binding to short DNA motifs called E-boxes within their target CRMs to modulate chromatin state and to fine-tune gene expression output. more...

(Submitter supplied) Rhabdomyosarcoma (RMS) is a pediatric malignancy of mesenchymal origin. Fusion Negative-RMS (FN-RMS) tumors are associated with RAS-pathway activation. RMS tumors express pro-differentiation myogenic transcription factors MYOD and MYOG, yet why they are unable to differentiate is poorly understood. Here we show that SNAI2 is highly expressed in FN-RMS, is regulated by MYOD and blocks myogenic differentiation promoting growth. more...

(Submitter supplied) INO80 complex is an ATPase-dependent chormatin remodeling complex, which regulates various DNA metabolic processes such as DNA replication and repair. Additionally, INO80 complex also contributes to the regulation of gene expression in sterss response and development. In order to investigate the function of INO80 complex in rhabdomyosarcoma, we examined the knockdown of subunits of INO80 complex Actr5, Ies6, and Ino80 in human rhabdomyosarcoma RD cells. more...

(Submitter supplied) We provide here an unprecedented analysis of the three-dimensional re-organization of the genome during cellular reprograming of one cell type into another by the ectopic expression of one single transcription factor. By integrating Hi-C analysis with ChIPseq-based detection of MYOD genome-wide binding and RNAseq profiling of gene expression, we discovered that MYOD causes profound alterations in the high order chromatin structure during fibroblast reprogramming into skeletal muscle cells. 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...
