Sample GSM1171525 Query DataSets for GSM1171525
Status Public on Jun 21, 2013
Title Veh_2
Sample type SRA
 
Source name Immortalized human breast cancer cells
Organism Homo sapiens
Characteristics treatment: Vehicle
replicate: 2
Extracted molecule total RNA
Extraction protocol After 1 hour of E2 or Vehicle treatment, nuclei from C4-12/Flag-ERβ cells were extracted and processed with nuclear run-on assay.
Run-on RNA was ligated with adapters and reverse transcribed to generate cDNA library.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Description GROseq - Global run-on followed by sequencing
Data processing Alignment: Short-reads were aligned to the human reference genome (hg18, NCBI36), including autosomes, X-chromosome, and one complete copy of an rDNA repeat (GenBank ID: U13369.1). The SOAP2 software package was used to align reads with the following options: (1) all non-unique mappings were removed (-r 0), (2) three mismatches were allowed in each mapped read (-v 3), (3) low-quality reads with more than 10 ambiguous bases were removed (-N 10), and (4) for reads failing to align over the entire length of the read, the first 32 bp was used (-l 32). SOAP2 output was processed using custom Perl scripts, and imported into R for most the analysis. In order to identify E2-regulated genes, we focused on RefSeq-annotated genes, counting reads in a fixed window between +1 kb and +13 kb relative to the transcription start site of each gene, so as to avoid possible complications introduced by paused polymerases, and to allow easy side-by-side comparison among samples. The normalized expression value of 1e-5 (normalized against the sample total read counts) was used as the threshold to select genes for further analyses. Comparing E2 treated samples versus vehicle treated samples, genes with FC>1.2 were considered upregulated; those with FC<0.8 were considered downregulated.
