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.

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.
