Transcription profiling of human Rhabdomyosarcoma biopsy samples (15 embryonal RMS, 10 translocation-positive alveolar RMS and 5 translocation-negative alveolar RMS)

ABSTRACT: We measured the expression profiles of a series of 30 Rhabdomyosarcoma biopsy samples (15 embryonal RMS, 10 translocation-positive alveolar RMS and 5 translocation-negative alveolar RMS). Expression data was used for unsupervised hierarchical clustering as well as supervised analysis to find gene expression signatures characteristic for the different histological RMS subgroups.

Rhabdomyosarcoma is a pediatric tumor type, which is classified based on histological criteria into two major subgroups, namely embryonal rhabdomyosarcoma and alveolar rhabdomyosarcoma. The majority, but not all, alveolar rhabdomyosarcoma carry the specific PAX3(7)/FKHR-translocation, whereas there is no consistent genetic abnormality recognized in embryonal rhabdomyosarcoma. To gain additional insight into the genetic characteristics of these subtypes, we used oligonucleotide microarrays to mea ...[more]

Endothelial and Alveolar Rhabdomyosarcoma mRNA expression

Project description:Frozen skeletal muscle, tumor adjacent skeletal muscle, Endothelial Rhabdomyosarcoma (ERMS) and Alveolar Rhabdomyosarcoma (ARMS) samples were profiled on Illumina bead array. Total RNA from primary resected samples were profiled to allow comparison of 1) normal skeletal muscle tissue with RMS samples and 2) ARMS with ERMS tumors.

Mouse Models of Alveolar/Embryonal Rhabdomyosarcoma & Spindle Cell Sarcomas

Project description:A series of conditional mouse models of embryonal rhabdomyosarcoma, alveolar rhabdomyosarcoma and spindle cell sarcoma were generated and validated for relavence to corresponding human cancers. Conditional mouse models of embryonal rhabdomyosarcoma, alveolar rhabdomyosarcoma and spindle cell sarcoma were created by activation or deletion of Pax3:Fkhr, p53, Ptch1 or Rb1 genes.

Piperacetazine directly binds to the PAX3::FOXO1 fusion protein and inhibits its transcriptional activity

Project description:The tumor-specific chromosomal translocation product, PAX3::FOXO1, is an aberrant fusion protein that plays a key role for oncogenesis in the alveolar subtype of rhabdomyosarcoma (RMS). PAX3::FOXO1 represents a validated molecular target for alveolar RMS and successful inhibition of its oncogenic activity is likely to have significant clinical applications. Even though several PAX3::FOXO1 function-based screening studies have been successfully completed, a directly binding small molecule inhibitor of PAX3::FOXO1 has not been reported. Therefore, we screened small molecule libraries to identify compounds that were capable of directly binding to PAX3::FOXO1 protein using surface plasmon resonance technology. Compounds that directly bound to PAX3::FOXO1 were further evaluated in secondary transcriptional activation assays. We discovered that piperacetazine can directly bind to PAX3::FOXO1 protein and inhibit fusion protein-derived transcription in multiple alveolar RMS cell lines. Piperacetazine inhibited anchorage-independent growth of fusion positive alveolar RMS cells but not embryonal RMS cells. Based on our findings, piperacetazine is a molecular scaffold upon which derivatives could be developed as specific inhibitors of PAX3::FOXO1. These novel inhibitors could potentially be evaluated in future clinical trials for recurrent or metastatic alveolar RMS as novel targeted therapy options.

Targeting KDM4 for treating PAX3-FOXO1-driven alveolar rhabdomyosarcoma [RNAseq_LHCN_hg19]

Project description: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. Genetic and pharmacologic inhibition of KDM4B significantly delays tumor growth by disrupting the expression of CRC TFs caused by epigenetic alterations of PAX3–FOXO1-governed super enhancers. Combining KDM4B inhibition with cytotoxic chemotherapy leads to significant tumor regression in preclinical PAX3–FOXO1+ RMS models. In summary, we have identified a targetable mechanism required for maintenance of PAX3-FOXO1-related CRC TF network, which may translate to a novel therapeutic approach for fusion-positive RMS.

Rhabdomyosarcoma surfaceome profiling with six fusion-positive (FP) RMS cell lines, five fusion-negative (FN) RMS cell lines, and three ARMS patient-derived xenografts (PDXs)

Project description:Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children. Prognosis for patients with high grade and metastatic disease is still very poor, and survivors are burdened with long-lasting side effects. Therefore, more effective and less toxic therapies are needed. Surface proteins are ideal targets for antibody-based therapies, like bispecific antibodies, antibody drug conjugates, or chimeric antigen receptor (CAR) T cell. Specific surface targets for RMS are scarce. Here, we performed a surfaceome profiling based on differential centrifugation enrichment of surface/membrane proteins and detection by LC-MS on six fusion-positive (FP) RMS cell lines, five fusion-negative (FN) RMS cell lines, and three RMS patient-derived xenografts (PDXs). 699 proteins were detected in the three RMS groups. Ranking based on expression levels and comparison to expression in normal MRC-5 fibroblasts and myoblasts, followed by statistical analysis, highlighted known RMS targets such as FGFR4, NCAM1, and CD276/B7-H3, and revealed AGRL2, JAM3, MEGF10, GPC4, CADM2, as potential targets for immunotherapies of RMS. L1CAM expression was investigated in RMS tissues and strong L1CAM expression was observed in more than 80% of alveolar RMS tumors, making it a practicable target for antibody-based therapies of alveolar RMS.
