Sample GSM1669141 Query DataSets for GSM1669141
Status Public on May 22, 2015
Title JC2573_Xenograft_MCF7_ER_E2 r10
Sample type SRA
 
Source name Xenograft_MCF7_ER_E2
Organism Homo sapiens
Characteristics implated cell line/type: MCF7; MCF7-Luc2/YFP cells
host strain: age-matched female NOD/SCID/IL2Rg-/- (NSG)
tissue: xenografts tumors in vivo
treatment groupd: E2
chip antibody: ERα Antibody (HC-20)
chip antibody vendor: Santa Cruz
chip antibody cat. #: sc-543
chip antibody lot #: A2213
Treatment protocol 90 day slow-release 17b-estradiol (0.72 mg/pellet) and/or progesterone (10 mg/pellet) and/or placebo hormone pellets (Innovative Research of America) were implanted subcutaneously in recipient mice. Concomitantly, ovariectomisation was performed.
Growth protocol Age matched female NOD/SCID/IL2Rg-/- (NSG) mice were injected subcutaneously into the No 4 inguinal mammary fat pad with a suspension of 10^5 MCF7-Luc2/YFP cells in 50% growth factor reduced MatrigelTM (BD Biosciences).
Extracted molecule genomic DNA
Extraction protocol immunoprecipitated DNA was end-repaired, A-tailed, ligated to the sequencing adapters, amplified by 18 cycles of PCR and size selected (200-300 bp) followed by single end 4 sequencing on an Illumina HiSeq 2000 according to the manufacturer’s recommendationas described in Chandra, T. et al. Independence of Repressive Histone Marks and ChromatinCompaction during Senescent Heterochromatic Layer Formation. Mol Cell 47, 203–214 (2012)
 
Library strategy ChIP-Seq

Description ChIP for ER in xenograft (MCF7 cells grown in mouse) after E2 treatment [Tumour #10]
Data processing Single-end reads were aligned against the Human Reference Genome (assembly hg19, NCBI GRCH37) using BWA version 0.5.5. Reads were filtered by removing those with a BWA alignment quality score less than 15. A further filtration was carried out by removing reads falling into the 'blacklist' regions identified by ENCODE.
Quality was confirmed using Biocnoductor package ChIPQC. Peaks we called using MACS v 1.4.1.
The Bioconductor package DiffBind was used to determine clustering, formulate consensus peaksets, and identify differentially bound sites.
Genome_build: hg19, Genome Reference Consortium GRCh37
Supplementary_files_format_and_content: MACS peaks in .csv file format (named as .txt as per MACS software)
