Project description:Ewings Sarcoma (ES) belongs to the group of bone cancers defined by the existence of a certain EWS-ETS fusion gene. In this study we use the model cell line CADO-ES1 (EWSR1-ERG fusion gene) to characterize the genomic structure in respect to CNV and fusion gene events.
Project description:Analysis of differentially expressed genes in wild type SK-ES1 Ewing Sarcoma cells when compared to SK-ES1 Ewing Sarcoma cells that received six 4 Gy fractions (cumulative dose of 24 Gy) of ionizing radiation (radiation-adapted cell line). The hypothesis tested being that repeated ionizing radiation exposure of modifies radiation therapy response in Ewing Sarcoma.
Project description:EWSR1-FLI1 is a chimeric transcription factor resulting from the pathognomonic translocation present in Ewing sarcoma cells. Here, we silenced EWSR1-FLI1 in different Ewing sarcoma cell lines. RNA from SKNMC, TC71 and MHH-ES1 cells was extracted 96h post transfection (siCT or siEWSR1-FLI1) or prior doxycycline (day 0) and 7 days after inducing silencing of EWSR1-FLI1 with doxycycline in ASP14 cells. RNA-seq was performed for all conditions.
Project description:Ewing tumor cell line SBSR-AKS grows adherent to the culture vessel. A spontaneously derived sub-line of cell line SBSR-AKS shows growth in suspension. We used microarrays to analyse gene expression in these Ewing tumor cell lines Established Ewing tumor cell lines were grown under standard conditions

Project description:The hallmark of human cancer is heterogeneity, mirroring the complexity of genetic and epigenetic alterations acquired during oncogenesis. We extracted DNA of 14 cultured human ovarian carcinoma cell lines subjected to pooled shRNA screen using TRC 1.0 library, and performed DNAseq. 14 ovarian carcinoma cell lines DNAseq data.
Project description:Cell lines have been essential for major discoveries in cancer including Ewing sarcoma (EwS). EwS is a highly aggressive pediatric bone or soft-tissue cancer characterized by oncogenic EWSR1-ETS fusion transcription factors converting polymorphic GGAA-microsatellites (mSats) into neo-enhancers. However, further detailed mechanistic evaluation of gene regulation in EwS have been hindered by the limited number of well-characterized cell line models. Here, we present the Ewing Sarcoma Cell Line Atlas (ESCLA) comprising 18 EwS cell lines with inducible EWSR1-ETS knockdown that were profiled by whole-genome-sequencing, DNA methylation arrays, gene expression and splicing arrays, mass spectrometry, and ChIP-seq for EWSR1-ETS and histone marks. Systematic analysis of these multi-dimensional data identified GATA2 and E2F2 as EWSR1-ETS-driven putative co-regulatory transcription factors. To evaluate the relevance of these transcrition factors, RNA interference in a Ewing sarcoma cell line was employed with subsequent Affymetrix Exon array profiling. The expression data were analysed in synopsis with the effects of EWSR1-FLI1 in the same cell line.
