Analysis of Ewing family tumor (EFT) and neuroblastoma (NB) samples. Distinguishing EFTs from other small round blue cell tumors (SRBCTs), such as NBs, by histologic methods is often difficult. Results identify EF-associated genes that enable molecular discrimination between EFTs and other SRBCTs.

(Submitter supplied) The cellular origin of Ewing tumor (ET), a tumor of bone or soft tissues characterized by specific fusions between EWS and ETS genes, is highly debated. Through gene expression analysis comparing ETs with a variety of normal tissues, we show that the profiles of different EWS-FLI1-silenced Ewing cell lines converge toward that of mesenchymal stem cells (MSC). Moreover, upon EWS-FLI1 silencing, two different Ewing cell lines can differentiate along the adipogenic lineage when incubated in appropriate differentiation cocktails. more...

(Submitter supplied) The molecular hallmark of the Ewing family of tumors is the presence of balanced chromosomal translocations leading to the formation of chimerical transcription factors (i.e. EWS/FLI1) that play a pivotal role in the pathogenesis of Ewing tumors by deregulating gene expression. We have recently demonstrated that DAX1 (NR0B1), an orphan nuclear receptor which was not previously implicated in cancer, is induced by the EWS/FLI1 oncoprotein and is highly expressed in Ewing tumors, suggesting that DAX1 is a biologically relevant target of EWS/FLI1-mediated oncogenesis. more...

(Submitter supplied) Ewing sarcoma is characterized by pathognomonic translocations fusing most frequently EWSR1 with FLI1 (EF1). In addition, Ewing sarcoma can also display alterations in STAG2, TP53 and CDKN2A (SPC). Starting from Ewing sarcoma derived human mesenchymal stem cells (MSCpat), we recapitulated this translocation and SPC alterations using a CRISPR/cas9 approach and generated a bona fide Ewing sarcoma model (EWIma1) displaying transcriptomic and epigenetic hallmarks of EwS.

(Submitter supplied) Human Ewing sarcoma cell line EW-8 with different levels of EWSR/FLI1 using siRNA-EWSR1 were collected and profiled using single-cell RNA-seq. The single-cell RNA-sequencing data identified diverse reponses leading to the prediction of two rare cell identities in an unperturbed population (si-Control) with stem-like and dormant-like characterisitics. These newly discovered cell states may play important roles in undrstanding cancer heterogeneity, drug resistance and recurrence in Ewing sarcoma .

(Submitter supplied) Oncogenic transformation in Ewing sarcoma tumors is driven by the fusion oncogene EWS-FLI1. The inducible expression of EWS-FLI1 (EF) in embryoid bodies, or collections of differentiating stem cells, generates cells with properties of Ewing sarcoma tumors, including characteristics of transformation. These cell lines exhibit anchorage-independent growth, a lack of contact inhibition and a strong Ewing sarcoma gene expression signature. more...

Expression was analyzed in stem cell conditions 5 days after transduction (undifferentiated conditions) and after 6 weeks in differentiation media (differentiation conditions). Changes in gene expression over time were compared between control and EWS-FLI1 expresssing cells.

(Submitter supplied) Ewing sarcoma, a rare and aggressive pediatric cancer, is characterized by chromosomal translocations that give rise to chimeric transcription factors. The most frequent of these chromosomal translocations is the t(11;22) that produces the fusion of the EWSR1 and FLI1 genes to generate the chimeric transcription factor EWSR1::FLI1. EWSR1::FLI1 is the main oncogenic event in Ewing's sarcoma. Recently, it has been proposed that EWSR1::FLI1 levels may fluctuate in Ewing sarcoma cells, giving rise to two cell populations: cells expressing low levels of EWSR1::FLI1 are characterized by a more migratory and invasive phenotype, while cells expressing high levels of EWSR1::FLI1 are more proliferative. more...
