Sample GSM1035405 Query DataSets for GSM1035405
Status Public on Dec 04, 2012
Title rat_ts_3seq_rep1
Sample type SRA
 
Source name Trophoblast stem cells
Organism Rattus norvegicus
Characteristics strain: HSD
cell type: Trophoblast stem cells
Growth protocol Mouse TSCs were obtained from Dr. Janet Rossant, Hospital for Sick Children, (Toronto, Canada) and maintained in DMEM/F12 with 15 mM Hepes, 20% FBS, 2 mM glutamine, 100 ug/ml streptomycin, 1 mM sodium pyruvate, 100 uM BME, supplemented with Activin, FGF4, and Heparin following (Erlebacher et al, Developmental Biology 2004). Rat TSCs were cultured as previously (Asanoma et al, Developmental Biology 2011)
Extracted molecule polyA RNA
Extraction protocol mRNA was extracted directly from cell lysates using Dynabeads Oligo (dT)25 (Invitrogen).
500 ng of mRNA was then used to prepare 3’ RNA-Seq libraries as previously described (Beck et al, PLOS One 2010). Briefly, mRNA was heat sheared for 7 minutes to produce an average fragment size range of 300-500 bp, then used to generate cDNA libraries using a custom oligo dT primer containing Illumina-compatible adapter sequence. cDNA fragments were end-repaired and ligated to standard Illumina adapters. Size-selection was performed using E-gel SizeSelect agarose gels (Invitrogen), products were PCR amplified for 15 cycles, and purified using Ampure XP beads. Library quality was assessed using Bioanalyzer and Qubit, and sequenced on the Genome Analyzer IIx.

Description mRNA
Data processing Basecalls performed using CASAVA version 1.5
ChIP-seq reads were aligned to mm9 or rn4 using Bowtie 0.12.7 with the settings --best --strata -k 10 -S --chunkmbs 190
Using Unipeak v1.0, Bowtie alignments were filtered by posterior probability (sam_map.pl from Unipeak), and transcription peaks were called using default settings.
Peaks (chromosomal coordinates) were associated with Ensembl (e67) gene database for mouse and rat, and multiple peaks for each gene were pooled.
Genome_build: mm9
Supplementary_files_format_and_content: txt files contain pooled gene x raw tag count
