(Submitter supplied) Sarcomas are derailed in pathways that specify mesenchymal lineages during embryogenesis, causing tumor cells to stall at early stages of differentiation. Among them, rhabdomyosarcoma (RMS) is a pediatric soft tissue sarcoma of skeletal muscle origin. A key feature of RMS is their inability to terminally differentiate despite the high expression of master myogenic regulator MYOD. The bHLH transcription factor TWIST2, which governs mesenchymal stem cell identity and restricts myogenesis, is overexpressed in patient fusion-negative RMS (FN-RMS) tumors. more...

(Submitter supplied) Integrated analysis of genome-wide ChIP-Seq and RNA-Seq data revealed the first dynamic chromatin and transcriptional landscape of Twist2 binding during myogenic differentiation. During differentiation, Twist2 competes with MyoD at shared DNA motifs to direct global gene transcription and repression of the myogenic program. Additionally, TWIST2 shapes the epigenetic landscape to drive chromatin opening at oncogenic loci and chromatin closing at myogenic loci. 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) Rhabdomyosarcoma (RMS) is a highly malignant pediatric cancer of skeletal muscle lineage. The aggressive alveolar subtype is commonly characterized by t(2;13) or t(1;13) translocations with the expression of PAX3- or PAX7-FOXO1 fusion transcription factors respectively and is known as fusion positive RMS (FP-RMS). FP-RMS tumors rely on the fusion gene to maintain their proliferative state while avoiding terminal differentiation program. more...

(Submitter supplied) Activation of identity determining transcription factors (TFs), or core regulatory TFs, is governed by cell-type specific enhancers, an important subset of these being super enhancers (SEs). This mechanism is distinct from constitutive expression of housekeeping genes. The characterization of drug-like small molecules to selectively inhibit core regulatory circuitry is of high interest for treatment of cancers, which are addicted to core regulatory TF function at SEs. more...

(Submitter supplied) The fusion transcription factor PAX3-FOXO1 drives oncogenesis in a subset of rhabdomyosarcomas, however the mechanisms by which it remodels chromatin are unknown. We find PAX3-FOXO1 reprograms the cis-regulatory landscape by inducing super enhancers (SEs), in collaboration with master transcription factors MYOG, MYOD and MYCN. This myogenic SE circuitry is consistent across cell lines and primary tumors. more...

(Submitter supplied) Genetic and shRNA-mediated inhibition of SIX1 expression in RMS cells induces myogenic differentiation and impedes RMS tumor growth. To elucidate the mechanism by which SIX1 loss activates a differentiation program, we performed SIX1, MYOD1, and H3K27ac ChIPseq in two SIX1 knockdown SMS-CTR cell lines and one control SMS-CTR cell line to profile changes in transcriptional activity and myogenic transcription factor binding in fusion-negative Rhabdomyosarcoma.

(Submitter supplied) Rhabdomyosarcoma (RMS) is a pediatric mesenchymal-derived malignancy encompassing Fusion Positive (FP)-RMS expressing PAX3/7-FOXO1 and Fusion Negative (FN)-RMS often mutated in the RAS pathway. RMS expresses the master myogenic transcription factor MYOD that, paradoxically, is unable to support differentiation while essential for tumor cell survival. We identify here SKP2, an oncogenic E3-ubiquitin ligase, as a critical driver of tumorigenesis in FN-RMS. more...
