| Title |
TC-32 siFLI1, H3K4me3, rep 1 |
| Sample type |
SRA |
| |
|
| Source name |
TC-32
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: TC-32
cell type: Ewing sarcoma
chip antibody: H3K4me3 (EpiCypher, #13-0041)
sirna: siFLI1
|
| Treatment protocol |
RNAi-based studies, cells were reverse transfected with 20 nM siRNA complexed with Lipofectamine RNAi-Max (Invitrogen). siNeg (SI03650318, Qiagen) and siFLI1 (s5266, Thermo Fisher Scientific)
|
| Growth protocol |
Cells were cultured in RPM1 1640 supplemented with 10% FBS and Plasmocin Prophylactic (Invivogen, San Diego, CA), and grown at 37°C, 5% CO2. We confirmed the identity of cell lines using short tandem repeat (STR) analysis (ATCC) at intervals throughout experimentation, and we monitored for mycoplasma contamination using the MycoAlert Plus system (Lonza, Walkersville, MD)

| Extracted molecule |
genomic DNA |
| Extraction protocol |
ChIP assays were performed using SimpleChIP plus Enzymatic Chromatin IP kit (9005S; Cell Signaling Technology, Danvers, MA). Briefly, cells were crosslinked with final concentration of 1% formaldehyde for 10 miunites. After quenching, cell lysis and enyzmatically digested, chromatin was sonicated using Branson SFX250 Digital Sonifier (Branson Ultrasonics) to obtain a fragment size of 200 - 900 bp. Solubilized chromatin was immunoprecipitated with the indicated antibodies and Protein G-Dynabeads (Thermo Fisher Scientific).
ChIP-seq libraries were using SMARTer ThruPlex TAKARA Library Prep kit following manufacturer's instructions. 10 ng of DNA was used as starting material for input and IP samples. Libraries were amplited using 8 cycles on the thermocycler.

| Data processing |
ChIP-seq analysis were carried out using center for cancer research bioinfoirmatics resource (CCBR) pipeline (https://github.com/CCBR/Pipeliner/wiki/Pipeline-Documentation - chip-seq)
Sequence reads were triimmed for adaptor sequence using cutadapt v4.4
trimmed reads were aligned to GRCh38/hg38 human genes and Drosophila Melanogaster dm6 genes using BWA mem v.0.7.17
PCR duplicates were removed with the Picard v.2.17.11 SamToFasq (for blacklist read removal) and MarkDuplicates (to remove PCR duplicates)
Peak calling was performed against input control using model-based MACS2 v2.1.1, with the cut-off q-value < 0.02.
Assembly: GRCh38/hg38
Supplementary files format and content: narrowPeak (except for Input sample)
