(Submitter supplied) We identified global DNA binding properties of EWS-FLI1 in mouse Ewing sarcoma. GGAA microsatellites were found as binding sites of EWS-FLI1 but with less frequency than that in human Ewing sarcoma, and genomic distribution is not conserved between human and mouse.

(Submitter supplied) CIC-DUX4 sarcoma (CDS) or CIC-rearranged sarcoma is a subcategory of small round cell sarcoma resembling the morphological phenotypes of Ewing sarcoma (ES). Recent clinicopathologic and molecular genetic analyses indicate that CDS is an independent disease entity from ES. Although a few ancillary markers have been used in the differential diagnosis of CDS, additional CDS-specific biomarkers are needed in challenging diagnosis for a more definitive classification. more...

(Submitter supplied) We have performed a high-throughput RNA interference screen to identify targets inhibiting EWS-FLI1 driven cell proliferation in Ewing sarcoma cells. EWS-FLI1 expressing A673 Ewing sarcoma cells were screened both in presence and absence of EWS-FLI1 shRNA induction with druggable siRNA library. Leucine rich repeats and WD repeat Domain containing 1 (LRWD1) targeting siRNA pool was the strongest anti-proliferative hit identified only in presence of EWS-FLI1. more...

Analysis of Ewing sarcoma cell line A673sh (a doxycycline-inducible, EWS-FLI1-shRNA expressing derivative of A673) transfected with pRS-sh-FOXO1 plasmid targeting FOXO1wt, in the presence or absence of Dox. Results provide insight into FOXO1's contribution to the EWS-FLI1 transcriptional signature.

(Submitter supplied) Posterior homeobox D genes, in particular HOXD13, are over-expressed by Ewing sarcoma, a tumor driven by the oncogenic fusion protein EWS-FLI1. Here, we have found that EWS-FLI1 maintains HOXD13 expression through a GGAA microsatellite enhancer in the developmental posterior HOXD regulatory domain. RNA-seq of shHOXD13 defined HOXD13-ergulated genes, so we performed CUT&RUN for HOXD13 and histone marks (H3K27ac, H3K4me3, H3K4me1, and H3K27me3) to determine how it regulates target genes.

Here, we have found that EWS-FLI1 maintains HOXD13 expression through a GGAA microsatellite enhancer in the developmental posterior HOXD regulatory domain. Activation of this enhancer is EWS-FLI1 dependent and epigenomic silencing of this region leads to loss of HOXD13 expression in Ewing sarcoma cells, but not in unrelated cells. more...

(Submitter supplied) Ewing sarcoma usually expresses the EWS/FLI fusion transcription factor oncoprotein. EWS/FLI regulates myriad genes required for Ewing sarcoma development. EWS/FLI binds GGAA-microsatellite sequences in vivo and in vitro, and these sequences provide EWS/FLI-mediated activation to reporter constructs, suggesting that they function as EWS/FLI-response elements. Genomic GGAA-microsatellites are highly variable and polymorphic. more...

(Submitter supplied) Ewing sarcoma is a bone malignancy of children and young adults, frequently harboring the EWS/FLI t(11;22)(q24;q12) chromosomal translocation. The resulting fusion protein is an aberrant transcription factor that uses highly repetitive GGAA-containing elements (microsatellites) to activate and repress thousands of target genes mediating oncogenesis. However, the mechanisms of EWS/FLI interaction with microsatellites and regulation of target genes expression is not clearly understood. more...

(Submitter supplied) Ewing sarcoma (EwS) is a rare bone and soft tissue malignancy driven by chromosomal translocations encoding chimeric transcription factors, such as EWSR1-FLI1, that bind GGAA motifs forming novel enhancers that alter nearby expression. We propose germline microsatellite variation at the 6p25.1 EwS susceptibility locus could impact downstream gene expression and EwS biology. We performed targeted long-read sequencing of EwS blood DNA to characterize variation and genomic features important for EWSR1-FLI1 binding. more...

(Submitter supplied) As the second most common malignant bone tumor in children and adolescents, Ewing sarcoma is initiated and exacerbated by a chimeric oncoprotein, most commonly, EWS-FLI1. In this study, we apply epigenomic analysis to characterize the transcription dysregulation in this cancer, focusing on the investigation of super-enhancer and its associated transcriptional regulatory mechanisms. We demonstrate that super-enhancer-associated transcripts are significantly enriched in EWS-FLI1 target genes, contribute to the aberrant transcriptional network of the disease, and mediate the exceptional sensitivity of Ewing sarcoma to transcriptional inhibition. more...
