Sample GSM3336881 Query DataSets for GSM3336881
Status Public on Dec 11, 2019
Title TAMR_H3K4me1_ChIP-seq
Sample type SRA
 
Source name TAMR
Organism Homo sapiens
Characteristics cell line: MCF7
cell type: breast cancer cells
resistant phynotype: tamoxifen-resistant
chip antibody: H3K4Me1 Active Motif 39297
Growth protocol MCF7 breast cancer cells, and the corresponding endocrine resistant sub cell lines were kindly given to our laboratory by Dr Julia Gee (Cardiff University, UK). MCF7 cells were maintained in RPMI-1640 based medium containing 5% (v/v) fetal calf serum (FCS). Tamoxifen-resistant MCF7 (TAMR) cells were generated by the long-term culture of MCF7 cells in phenol-red-free RPMI medium containing 5% charcoal stripped FCS and 4-OH-tamoxifen (1×10-7 M) (TAM). Fulvestrant-resistant MCF7 (FASR) cells were generated by the long-term culture of MCF7 cells in phenol-red-free RPMI medium containing 5% charcoal stripped FCS and fulvestrant (1×10-7 M) (FAS). Endocrine resistant sub lines were established and characterised following 6 months endocrine challenge. All cell lines were authenticated by short-tandem repeat (STR) profiling (Cell Bank, Australia) and cultured for less than 6 months after authentication.
Extracted molecule genomic DNA
Extraction protocol Nuclei were purified after formaldehyde crosslinking, collected and resuspended in SDS Lysis buffer before sonication. Chromatin was sonicated to generate a majority of fragments between 200 and 600 bp. 10µg of each antibody was used per ChIP.
Libraries for ChIP-Seq were prepared following Illumina protocols. The resulting libraries were sequenced on the Illumina HiSeq 2000 platform configured for 50bp single-end reads.

Description USC20140306_TAMR_H3K4me1
Data processing ChIP-seq reads were aligned to hg38 using bowtie v2.2.4 allowing up to 3 mismatches, discarding ambiguous and clonal reads. Peaks were called with Macs2 version 2.0.10.
Genome_build: hg38
Supplementary_files_format_and_content: Bigbed files were generated using Macs2 version 2.0.10.
