Sample GSM1152972 Query DataSets for GSM1152972
Status Public on Nov 09, 2016
Title Immunoprecipitated mRNAs with control IgG
Sample type SRA
 
Source name pancreatic cancer
Organism Homo sapiens
Characteristics cell line: S2-013
antibody: control IgG
cell type: pancreatic cancer
Extracted molecule total RNA
Extraction protocol Fibronectin-stimulated S2-013 cells were lysed in NP2 buffer containing 50 mM Tris (pH 7.4), 150 mM NaCl, 1 mM MgCl2, 0.5% NP-40 and protease and RNAse inhibitors.
RIP protocol: Cell lysates were immunoprecipitated with anti-IGF2BP3 antibody or with normal rabbit IgG and Dynabeads Protein G (Dynal, Oslo, Norway) for 2 h at 4ºC. Beads were pelleted on a magnetic rack (Dynal). The immunoprecipitation products were treated with proteinase K, extracted with phenol-chloroform, and precipitated with ethanol. Purified RNAs were subsequently treated with DNase I (Promega, Madison, WI) and extracted using the RNeasy kit (Qiagen, Valencia, CA) according to the manufacturer’s instructions. Finaly, RNAs were fragmented and purified using an Illumina TruSeq RNA Sample Prep Kit (San Diego, CA) according to the manufacturer’s instructions.
seq protocol: The IGF2BP3-associated mRNAs were identified using a next generation sequencer, Illumina HiSeq 2000 (Hokkaido System Science, Sapporo, Japan).

Description library strategy: RIP-Seq
Data processing The data obtained, Illumina/Solexa reads from the IP (IGF2BP3) experiment and from the control (IgG) were mapped to the mRNAs from RefSeq using the LSKB Database. We approximate the density of each mRNA by the RPKM measure (Reads per kilobase per Million of mapped reads). We normalized RPKM estimates using adjusting the mean and standard deviation of each sample’s log2(RPKM) values.

Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence, then mapped to SeqNovaTMCS (DNANexus).
We approximate the density of each mRNA by the RPKM measure (Reads per kilobase per Million of mapped reads) (Mortazavi A et al, Nat. Methods 5, 621-628, 2008). We normalized RPKM estimates using adjusting the mean and standard deviation of each sample’s log2(RPKM) values.
