(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) ATP-dependent chromatin remodelers modulate gene expression by regulating genome accessibility and can contribute to tumorigenesis. In fusion-positive rhabdomyosarcoma (FP-RMS), we have previously identified the chromatin remodeler and NuRD subunit CHD4 as an essential gene for tumor survival. Here, we demonstrate that the FP-RMS vulnerability to CHD4 goes beyond its function as a NuRD member. Mechanistically, CHD4 interacts with BRD4 and co-localizes with the tumor driver and fusion protein PAX3-FOXO1 at super-enhancers where it generates a chromatin architecture permissive for the binding of the fusion protein. 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) Circular chromatin confirmation capture in rhabdomyosarcoma cells was performed with viewpoints at the PAX3-FOXO1 bound super enhancer upstream of MYOD1, and also at the MYOD1 promoter, to find support for looping between these two genetic elements almost 80 thousand base pairs apart.

(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) PAX3-FOXO1 is a fusion transcription factor characteristic for the majority of alveolar rhabdomyosarcoma tumors. It is the main oncogenic driver and deregulates expression of PAX3 target genes. The PAX3-FOXO1 target gene signature was determined in the Rh4 alveolar rhabdomyosarcoma cell line.

(Submitter supplied) CHD4 is an ATPase able to use the energy from ATP to shift or remove nucleosomes from specific sites in the chromatin, thereby affecting accessability of gene regulatory elements. It is part of the NuRD complex. The effect of CHD4 on global gene expression was evaluated in Rh4 alveolar rhabdomyosarcoma cells.

(Submitter supplied) Chimeric transcription factors drive lineage-specific oncogenesis but are notoriously difficult to target. Alveolar rhabdomyosarcoma (RMS) is an aggressive childhood soft tissue sarcoma transformed by the pathognomonic PAX3–FOXO1 fusion protein, which governs a core regulatory circuitry transcription factor (CRC TF) network. Here we show that the histone lysine demethylase KDM4B is a therapeutic vulnerability for PAX3–FOXO1+ RMS. more...
