Sample GSM4259516 Query DataSets for GSM4259516
Status Public on Aug 08, 2021
Title MCF7 EtOH siCTL TT-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, 4sU 5 mins,siCTL
antibody: NA
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. Cells were labeled in media for 5 min with 700 μM 4-thiouridine (4sU, Sigma-Aldrich) and harvested through centrifugation for 1 min at 1,000g.
Growth protocol MCF7 cells were incubated in DMEM media supplemented with 10% Fetal Bovine Serum (FBS, GenDEPOT) in 37°C CO2 incubator.
Extracted molecule nuclear RNA
Extraction protocol RNA was extracted using TRIzol (Life Technologies), 4sU-labeled RNA was exctracted according to Duffy et al., Mol Cell, 2015.
RNA libraries were prepared using NEB Next Ultra II RNA library prep kit for illumina according to manufactorer's instructions
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
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.
