Sample GSM2149077 Query DataSets for GSM2149077
Status Public on Jul 08, 2016
Title RNASeq ABP1d 2
Sample type SRA
 
Source name ABPd
Organism Schizosaccharomyces pombe
Characteristics genotype/variation: ABP1d
Treatment protocol none
Growth protocol exponentially growing cells in rich media
Extracted molecule total RNA
Extraction protocol total RNA extraction by acid phenol protocol
total RNA was quantified by Qubit fluorometer using the Quant-iT RNA Assay Kit (Life Technologies). Using Illumina’s small RNA Sample Prep Kit v1.5, 3’ and 5’ adapters were ligated to 5 µg of total RNA, followed by reverse transcription and 12 cycles of amplification. Amplification products of 125 to 250 nucleotides size selected from a 4% agarose gel and purified. Libraries were quantified by Qubit fluorometer using the Quant-iT DNA HS Assay Kit (Life Technologies). Using Illumina’s Cluster Generation Kit, libraries were subject to cluster generation at 8 pM concentration as one sample per lane. Sequencing-by-synthesis was performed for 38 cycles.
Strand-specific RNA-Seq
 
Library strategy ncRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina Genome Analyzer II
 
Description smallRNAs_ABP1d_regions_geo.bed
smallRNAs_ABP1d_vs_WT_regions_geo.bed
Data processing Base calling was performed with Illumina Pipeline version 1.5
Solexa Illumina strand-specific small RNA-Seq data for Saccharomyces pombe in ABP1d mutant and wild type control samples were aligned against reference genome (Sanger release 09052011) using Bowtie 0.12.5, allowing 0 mismatches in the read seed. In order to estimate enrichment and depletion in repeated regions (i.e. transposons, rRNA units) in an unbiased manner, all possible sites for multiple hits were considered.
First, significantly enriched regions in small RNA-Seq ABP1d mutant and WT were detected using the enrichedRegions function from the htSeqTools package, using the one tailed option (no control) and a Benjamini Hochbergh pvalue threshold of 0.05, and leaving the other settings as default.
Afterwards, significantly enriched and depleted regions in small RNA-Seq ABP1d mutant against WT (up and down-regulated small RNAs) were detected using the enrichedRegions function from the htSeqTools package, using the two tailed option and a Benjamini Hochbergh pvalue threshold of 0.05, and leaving the other settings as default.

Supplementary_files_format_and_content: smallRNAs ABP1 and WT BED files include chromosome, start, end, rpkm abundance and BH adjusted pvalue of the identified enriched regions in each sample individually (no control).
Supplementary_files_format_and_content: smallRNAs ABP1_vs_WT BED file include chromosome, start, end, rpkm abundance in ABP1d and WT respectively, and BH adjusted pvalue of the identified regions differentially expressed in ABP1d vs WT.
