(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. 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) 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.

(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...

(Submitter supplied) Expression profiles were generated from hESC-derived neural crest stem cells following transduction with GFP control vector or EWS-FLI1 vector. 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 (EwS) is a EWS-FLI1- fusion driven pediatric bone cancer with high metastatic potential. Cellular plasticity, typically regulated via the Rho-pathway, is a prerequisite for metastasis initiation. Here we interrogated the role of the Rho transcriptional effectors MRTFA/B in EwS. We find MRTFB transcriptional function strongly repressed by EWS-FLI1. Under EWS-FLI1-low (knock-down) conditions, MRTFB is activated and antagonizes global EWS-FLI1-dependent transcription. more...

(Submitter supplied) RNA from A673 cells with shRNA-mediated knockdown of GFP (4 libraries), EWS-FLI1 (4 libraries), or lnc277 (7 libraries) was isolated with TRIzol (Invitrogen). Each sample was DNase treated and further purified on an RNeasy Mini column (Qiagen) before quality analysis on an Agilent 2100 Bioanalyzer. For each sample, 100-150ng of RNA was synthesized into cDNA, sheared on a Covaris ultrasonicator, and amplified using the NuGen Encore Complete kit (NuGen) to produce strand-specific and rRNA-depleted libraries. more...
