Sample GSM945787 Query DataSets for GSM945787
Status Public on Aug 01, 2012
Title RAS-ROSE cells treated with Klf6 siRNA 2
Sample type RNA
 
Source name Klf6_siRNA2
Organism Rattus norvegicus
Characteristics cell line: RAS-ROSE: KRAS-transformed Rose 199 cells
treatment: with Klf6 siRNA 2
Treatment protocol Cells were transfected twice with an interval of 24 h using Oligofectamine (Invitrogen), serum-free OptiMEM (Invitrogen) and a final siRNA concentration of 1 nM according to the manufacturer's specifications. After 4 h of incubation, FCS was added to the medium at a final concentration of 10 %.
Growth protocol RAS-ROSE cells were cultured in Dulbecco’s modified Eagle’s medium (DMEM) (Invitrogen) supplemented with 10 % fetal calf serum (FCS) (Sigma-Aldrich), 2 mM Ultraglutamine 1 (Lonza, BioWhittaker), and 100 units/ml penicillin/streptomycin (Biochrom AG) (standard medium). The medium was supplemented with G418 (400 μg/μl). 45000 RAS-ROSE cells were seeded into 6-well plates (BD Falcon) in standard medium 24 h prior to transient transfection of siRNA.
Extracted molecule total RNA
Extraction protocol Total RNA extraction were prepared using TRIZOL reagent (Invitrogen) according to the manufacturer’s instructions. CDNA synthesis was performed using the Ambion® WT Expression Kit (Ambion).
Label biotin
Label protocol 5.5 μg of the single-strand DNA was enzymatically fragmented with a combination of uracil DNA glucosylase (UDG) and apurinic/apyrimidinic endonuclease 1 (APE1) and biotinylated using the WT terminal labeling kit (Affymetrix).
 
Hybridization protocol Samples were hybridized accordingly to the manufacturer’s protocol using Hybridization Wash and Stain Kit (Affymetrix). The hybridization at 45°C and 60 rpm for 16hrs, the staining and washing were carried out as recommended by Affymetrix (Affymetrix).
Scan protocol GeneChipScanner 3000 G7 system (Affymetrix)
Description RAS-ROSE: KRAS-transformed Rose 199 cells (Tchernitsa et al., 2004; Adams and Auersperg, 1985)
RAS-ROSE cells treated with Klf6 siRNA 2
Data processing CEL files were analysed using bioconductor oligo package in R, normalisation was done using rma with target probeset.
