| Sample type |
SRA |

|
| Source name |
Ewing sarcoma cell line (TC71)
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: TC71
cell type: Ewing sarcoma cell line
genotype: WT
antibody: H3K4me3 (C15410003, Diagenode)
|
| Growth protocol |
A673 and TC71 were cultured respectively in DMEM or RPMI supplemented with 10% fetal bovine serum. Two days before performing the ChIP experiments, cells were seeded in T150 flask at a concentration allowing to reach a cellular confluence of approximately 90% at the time of fixation of the cells with formaldehyde.

genomic DNA |
| Extraction protocol |
ChiP were performed following manufacturer instructions using iDeal ChIP-seq kit for transcription factors and for histones (Diagenode). For this, Ewing cell lines were fixed for 10 minutes with 1% of methanol-free formaldehyde (28908, Thermo-Scientific). Chromatin was sonicated (Bioruptor, Diagenode) for 20 cycles (30-sec on, 30-sec off) set at position “high” to generate DNA fragments with an average size around 150-300pb.
The library were constructed using TruSeq ChIP library preparation kit (Illumina) according to manufacturer recommendations

| Data processing |
Reads were mapped with bowtie2 against human genome (hg19)
Peaks were called with MACS2 2.1.1 with the option narrow for FLI1, CTCF and cohesin members ChIP-seq and broad for histone marks. For each cell line, ChIP-seq were normalized according to their respective input DNA sample.
