Sample GSM1616198 Query DataSets for GSM1616198
Status Public on Mar 05, 2015
Title Patski_FirreKD_rep1
Sample type SRA
 
Source name Patski cells
Organism Mus musculus x Mus spretus
Characteristics strain: BL6/spretus
genotype/variation: stable Firre knockdown
cell type: Fibroblasts derived from hybrid embryonic kidney
Treatment protocol Two biological replicates from control or stable Firre knockdown (si&shRNA) Patski cells were used for RNA-seq.
Growth protocol Standard cell culturing protocol using 10% FBS in DMEM.
Extracted molecule total RNA
Extraction protocol RNA were extracted from Patski cells by the Qiagen RNeasy kit with on-column DNaseI digestion.
RNA-seq indexed libraries were prepared using Illumina TruSeq RNA sample preparation kit with standard Illumina protocols. Index adators 6 and 12 were used for Patski_control rep1 and 2 resepecitvely, as well as for Patski_Firre KD rep1 and 2 resepecitvely.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina Genome Analyzer IIx
 
Description The Patski fibroblast line was originally derived from BL6/spretus hybrid embryonic kidney and has the inactive X from BL6. Two individual RNA samples prepared from Patski cells with the Firre knockdown were used for indexed library preparation. Index adators 6 and 12 were used for Patski_Firre KD rep1 and 2 respectively.
Data processing Illumina Casava1.7 software used for basecalling.
Reads were first sorted by their index sequencing for each replicate. A pseudo-spretus genome was assembled by replacing available SNPs between C57BL/6J and M. spretus (Sanger Center) into the BL6 reference genome. 36bp reads were aligned to the C57BL/6J reference sequence (mm9, UCSC) and to the pseudo-spretus genome separately using TopHat with default parameters, except that the “min-isoform-fraction” flag was set to zero, "--no-novel-juncs" was specified to constrain the search to annotated exon:exon boundaries, and the RefSeq mouse gene annotation was used.
RPKM values were obtained using Cufflinks with default parameters and “min-isoform-fraction” set to zero.
Only high-quality uniquely-mapped reads were used for assignment to each haploid genome based on available SNPs.
The SNP-associated read counts were used to assess allelic expression.
Genome_build: mm9
Supplementary_files_format_and_content: tab-delimited text files include 5 columns: gene_id, locus, regular RPKM values, BL6-exon-SNP-read count, spretus-exon-SNP-read count.
