Sample GSM4029608 Query DataSets for GSM4029608
Status Public on Mar 13, 2020
Title Dm_S2cell_Biotin_dBRD4-S_ChIPseq_NSL1_RNAi_rep2_Input
Sample type SRA
 
Source name Dm_S2cell_Biotin_dBRD4-S_ChIPseq_NSL1_RNAi_Input
Organism Drosophila melanogaster
Characteristics cell line background: S2 cells
genotype/variation: S2 stable cell line:MtnA-dBRD4-S-FLAG-Biotin
knockdown or inhibitor treatment: NSL1 RNAi
chip antibody: streptavidin T1 magnetic beads (Invitrogen 65601)
Treatment protocol for RNAi: dsRNA was added to the cell culture medium, 10µg dsRNA per 1mio cells, cells were harvested after 4 days of RNAi, for dBRD4 inhibitor treatments: DMSO or inhibitor was added to the cell culture medium
Growth protocol Drosophila S2 cells (Invitrogen) were cultured in Express Five SFM media (Thermo Fisher) supplemented with 10% (v/v) Glutamax (Thermo Fisher). Cultures were maintained adherent or in shaking incubators at 27ºC at a speed of 80
Extracted molecule genomic DNA
Extraction protocol cells were fixed for 10min in 1.8% of formaldehyde at 23 °C, nuclei were isolated, chromatin was fragmented by sonication (Covaris), The lysate was clarified by centrifugation before immunoprecipitation, and eluted by reverse crosslinking at 65deg for 14h. After RNaseA and ProteinaseK treatment, the DNA from Input and Immunoprecipitation was purified using AMPure XP Beads (Beckman Coulter); for Rpb3 ChIP experiments Drosophila Virilis chromatin was added prior to IP as spike control. For Biotin ChIP experiments exogenous Biotin-labeled DNA fragments were added prior to IP as spike control.

Description dBRD4=fs(1)h , dBRD4-S indicating short isoform of dBRD4
Data processing Paired-end 75 bp reads were trimmed (TrimGalore, quality threshhold 20), then mapped using Bowtie2, BAM files of biological replicates were merged using SAM Tools
Coverage files were generated with deepTools3 (v3.0.1) bamCompare with a binsize of 1 (bin size of 10 for H3 profiles). The X chromosome was ignored for scaling. The data was normalized as follows: log2FC over Input for Drosophila H4K16ac, H3, Rpb3; Input subtraction for Drosophila Biotin-dBRD4-S and dBRD4. For Rpb3 profiles SES scaling (signal extraction method) was applied
Genome_build: dm6
Supplementary_files_format_and_content: bigwig file format, Input normalized ChIP enrichments
