Sample GSM4259524 Query DataSets for GSM4259524
Status Public on Aug 08, 2021
Title MCF7 EtOH siCTL ER-a ChIP-Seq
Sample type SRA
 
Source name MCF7
Organism Homo sapiens
Characteristics cell line: MCF7
cell type: human breast cancer cell line
treatment: EtOH 60 mins,siCTL
antibody: Era,Santa Cruz,sc-543
Treatment protocol In order to deprive hormone signaling in MCF7 cells, the cells were incubated in phenol red-free DMEM with 10% Charcoal-stripped fetal bovine serum (CS-FBS, Omega Scientific Inc) for 72 hours.EtOH were added to the cells for an hour.
Growth protocol MCF7 cells were incubated in DMEM media supplemented with 10% Fetal Bovine Serum (FBS, GenDEPOT) in 37°C CO2 incubator.
Extracted molecule genomic DNA
Extraction protocol Lysates were clarified from sonicated nuclei and chromatin were isolated with ER-a antibody.
DNA libraries were prepared using NEB Next Ultra II DNA library prep kit for illumina according to manufactorer's instructions
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model NextSeq 550
 
Data processing All clean-reads were mapped to human reference genome hg19 by STAR v2.7.0, with parameters of –-genomeSAindexNbases 14 –outFilterMultimapNmax 10 –outFilterMismatchNmax 10.   Duplicated reads were further removed, and only unique aligned reads will be considered for later visualization and quantification.
Genome build: hg19
MINT-Seq, TT-Seq, MeRIP-Seq,RNA-Seq, ChIP-Seq raw data were de-multiplexed by bcl2fastq (v2.20), and quality-controlled with fastqc.
All clean-reads were mapped to human reference genome hg19 by STAR v2.7.0, with parameters of –-genomeSAindexNbases 14 –outFilterMultimapNmax 10 –outFilterMismatchNmax 10.   Duplicated reads were further removed, and only unique aligned reads will be considered for later visualization and quantification.
For gene/mRNA quantification, hg19 RefSeq gene annotation coordinates were used. And HOMER tool-sets were used to calculate the FPKM value of individual repeat elements, based on repeat mask annotation. 
The unique aligned reads were further converted to bigwig format with a fragment length of 75 on IGV browser.
