Sample GSM2338073 Query DataSets for GSM2338073
Status Public on Feb 13, 2017
Title small RNA-seq_ade6-5'TNI wt
Sample type SRA
 
Source name small RNA sequencing from strain expressing siRNAs targeting an inserted non-splicable antisense cox4 intron in the ade6 5'UTR in wt background.
Organism Schizosaccharomyces pombe
Characteristics strain: SPB2496
genotype/variation: h- leu1-32 ura4-D18 ade6-target5 nmt1+::ura4-hp+-nat
genotype/variation: expressing siRNAs targeting an inserted non-splicable antisense cox4 intron in the ade6 5'UTR in wt background.
molecule subtype: size selected small RNA from whole cell lysate
illumina barcode: ACTTGA
Extracted molecule total RNA
Extraction protocol Total RNA was isolated from exponentially growing cells using hot phenol. The RNA was fractionated using RNeasy Midi columns (Qiagen). The flow-through fraction was precipitated and aliquots of 25 ug were separated by 17.5% PAGE to isolate the 18–28-nucleotide fraction.
Libraries were prepared using the Illumina TruSeq small RNA kit according to manufacturers instructions. For barcodes, see sample characteristics.
 
Library strategy miRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina HiSeq 2500
 
Description ade6-5'TNI wt
Data processing Samples were pooled and sequenced on an Illumina HiSeq 2500 instrument.
Demultiplexing and fastq conversion were performed with bcl2fastq2 v1.17.
Illumina 3' adaptors were trimmed using cutadapt with parameters -a TGGAATTCTCGGGTGCCAAGG --discard-untrimmed -m 18.
Fastq files were aligned to the S. pombe genome using Bowtie 1.0.0 with parameters -M 1 -v 0 --best --strata.
Bowtie sam out put was converted to bam using samtools (v1.3.1). Bam files were converted to bed using bedtools bamtobed (v2.25.0), Bed files were used to calculate strand-specific coverage using bedtools genomecov (v2.25.0) and resulting bedgraph files were converted to bigWig format using bedGraphToBigWig (v4).
Genome_build: S. pombe ASM294v2.24
Supplementary_files_format_and_content: bigWig files containing normalized (to 1 mio genome mapping reads per library) genome mapping read counts for visualization in UCSC or IGV.
