Sample GSM2198246 Query DataSets for GSM2198246
Status Public on Jun 15, 2016
Title Myc_1.5h_CaptureC_merge
Sample type SRA
Source name Myc_1.5h
Organism Mus musculus
Characteristics cell line: G1E ER4
treatment: estradiol 13h
transgene: stably expressing YFP-MD
nocodazole: 1.5h release
promoter anchor: Myc promoter
raw file ids merged: 825_979_973
Treatment protocol Except where indicated in the text as uninduced, we induced cells to mature with 100nM estradiol to activate GATA1-ER. During estradiol induction, we simultaneously treated cells with nocodazole (200ng/ml) for 7h-13h, washed once, and replated into fresh medium lacking nocodazole for varying times (40min-360min), ensuring all samples are exposed to estradiol for the same duration of 13h. We fixed cells with 1% formaldehyde, stained with DAPI, and sorted on a BD FACSAria based on YFP-MD and DAPI signal.
Growth protocol G1E erythroblasts were previously derived through deletion of GATA1 in mouse embryonic stem cells, followed by in vitro differentiation (Weiss, Yu, and Orkin 1997). We cultured a sub-line of G1E cells, G1E-ER4, in which GATA1-ER was retrovirally transduced (referred to in main text as “G1E GATA1-ER"), as previously described (Weiss, Yu, and Orkin 1997). We retrovirally transduced G1E-ER4 cells with the YFP-MD construct (Kadauke et al. 2012) and sorted for a pool of YFP-positive cells.
Extracted molecule genomic DNA
Extraction protocol After cell fixation with 1% formaldehyde for 10min and cell sorting as described above, Capture-C was performed with a double-capture procedure (Davies et al. 2016). Chromatin was digested using DpnII. We used biotin labelled DNA oligos to pull down the target restriction fragments.
Capture-C libraries were sequenced on Nextseq500 with 2x75 bp paired end sequencing.
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina NextSeq 500
Description Myc promoter anchor
Data processing Library strategy: Capture-C
The raw reads were processed using published scripts (
Custom scripts in R to normalize data by the total number of reads representing fragments ligated to the anchor region in the library.
For each time point and anchor, used custom scripts in R to combine reads representing fragments ligated to the anchor region in the library into one .bedgraph file merged across restriction digestion and/or capture replicates.
Genome_build: mm9
Supplementary_files_format_and_content: .bedgraph files containing coverage of reads (read counts of ligation products to given anchor region, per thousand total reads that represent ligation products to given anchor region).
