Sample GSM1085707 Query DataSets for GSM1085707
Status Public on Dec 05, 2013
Title transcriptome_DMSO
Sample type SRA
 
Source name MRC-5_transcriptome_DMSO
Organism Homo sapiens
Characteristics cell line: MRC-5
cell type: human fetal lung fibroblast Cell
Treatment protocol TCBQ powder was dissolved in DMSO with the concentration of 20mM for stock. MRC-5 cells with about 50% confluence were treated with TCBQ or DMSO diluted in culture media to the final concentration of 20uM for 24 hours.
Extracted molecule polyA RNA
Extraction protocol Total RNA was isolated from TCBQ/DMSO treated MRC-5 cells using RNAzol (Molecular Research Center, Inc.)
Poly(A) RNA from 1 ug of total RNA was used to generate the cDNA library according to TruSeq RNA Sample Prep Kit protocol which was then sequenced using the Illumina system.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Description processed data file: gene_exp.diff.txt
Data processing ChIP-seq reads were aligned to the hg19 genome assembly using BWA version 0.5.9-r16
Peaks were called using MACS version 1.4.2 with default parameter
We aligned those high quality reads to the masked Homo sapiens reference genome (hg19) genome and junction sequences using BWA 0.5.8 software allowing up to four mismatches. All the uniquely mapped reads were used to define gene expression level based on our developed method. We modified the RPKM (measured in reads per kilobase of exon per million mapped sequence reads, which is a normalized measure of exonic read density) calculation described by Mortazavi and colleagues to include junction fragments. By including reads that map to junction fragments, we ensure that genes with many introns are not under represented in the RPKM estimate. To examine differential expression, we used a MARS (MA-plot-based method with Random Sampling model) method to identify differentially expressed genes which described in DEGseq. For each gene, the P-value and Q-value were computed, and the fold changes were also calculated. Those genes with p < 0.001 and q-value < 0.05 were defined as DEGs.
Genome_build: hg19
Supplementary_files_format_and_content: The files are generated by MACS version 1.4.2, including chr, start, end, length, summit, tags, -10*log10(pvalue),fold_enrichment. The file of differitially expressed genes includes Gene, GeneNames, value1, value2, log2(Fold_change), log2(Fold_change) normalized, z-score, p-value, q-value(Benjamini et al. 1995), q-value(Storey et al. 2003), Signature(p-value < 0.001).
