Sample GSM1695011 Query DataSets for GSM1695011
Status Public on Mar 09, 2016
Title U6_sh_hAAT_25nt_rep3_Ago2IP
Sample type SRA
 
Source name liver - Ago2 IP
Organism Mus musculus
Characteristics tissue: liver
strain: C57Bl/6
Extracted molecule total RNA
Extraction protocol Large RNA samples were homogenized and extracted by Trizol; mRNAs were enriched through poly-A purification from a poly-A spin kit (NEB); small RNA samples were extracted using a miRvana microRNA isolation kit (samples 13-50) or total Trizol-extracted RNA (samples 51-93)
RNAseq library samples 1-6 were prepared using an Illumina TruSeq kit. RNAseq library samples 7-12 were prepared using a ScriptSeq v2 kit (Epicentre).
3ug of miRvana extracted or 5ug of Trizol extracted small RNAs were ligated to Linker-1 (IDT) in the absence of ATP with T4 RNA ligase 1 (New England Biolabs). Ligated RNA was size selected (based on an 18-36nt small RNA fraction) on 15% PAGE. The 5’ ends RNA were ligated to barcoded adapters. Dual-ligated RNA was reverse transcribed, PCR amplified and size selected on 4% NuSieve (Lonza) agarose. Small RNA sequencing was performed on the Illumina GAII (samples 13-50) and miSeq (samples 51-93) platforms.

Description Ago2IP_smallRNA_RPM.txt
Data processing RNAseq reads were aligned to the mm9 genome through a standardized pipeline generated by the Stanford Center for Genomics and Personalized Medicine
FPKM values were calculated by use of Cufflinks v2.2.1 with the following parameters: “--library-norm-method quartile” and removing ribosomal, snoRNA and mitochondrial sequences.
small RNA sequencing reads were sorted by barcode, barcode removed (4nt), linker-1 clipped and aligned to mouse hairpins from mirBase release 15 using bowtie (version 0.12.7) with 2 mismatches and command -- best
small RNA sequences from 293 cells were aligned to the miR-122 plasmid that was transfected and raw counts for each small RNA that was generated were tabulated
Genome_build: mm9, mirBase release 15
Supplementary_files_format_and_content: File of FPKM values for RNAseq samples, of reads per million (RPM) mapped microRNA hits for mouse small RNA sequencing samples, and alignment to a transfected plasmid in human cell line samples, all in tab delimited text format
