Sample GSM442839 Query DataSets for GSM442839
Status Public on Nov 24, 2009
Title FC-Disc1Mutant-Valproate-rep4
Sample type RNA
 
Source name frontal cortex, L100P mutant mouse, chronic treatment with valproate
Organism Mus musculus
Characteristics strain: C57BL/6
genotype: mutation Disc1 ENU L100P/L100P
sex: male
age: 10-12 weeks
tissue: frontal cortex
drug: Valproate
Treatment protocol Valproate (200 mg/kg, i.p) were given chronically (twice a day 9-10 am and 5-6 pm; for 15 days). Mice were tested in PPI on the next day after the last injection. Separated cohort of mice, treated in the same manner, have been used for molegular-genetic analysis. Brains were removed on the next day after the last injection of valproate.
Growth protocol Animals were bred and housed at the SLRI/MSH animal facility. Standard protocols were followed.
Extracted molecule total RNA
Extraction protocol Standard laboratory procedures for the handling of RNA were followed. All equipment was decontaminated of RNase with RNase Erase® solution followed by 90% ethanol and DEPC-treated water. Tissue was homogenized and lysed using Trizol® Reagent (Invitrogen Life Technologies Corporation, Carlsbad, CA). Chloroform was used to separate the aqueous and organic phases. The aqueous phase was washed with 70% ethanol at 0°C. Total RNA was purified from this solution using the Absolutely RNA Miniprep® kit (Stratagene, La Jolla, CA) according to the manufacturer’s instructions. Yield and quality of total RNA obtained was estimated by optical density measurements. An A260/280 value between 1.7 and 2.1 was considered relatively free of protein and suitable for further analysis. RNA samples were concentrated to approximately 0.08-0.1 µg/µL using Microcron YM-10 centrifugal filter devices (Millipore Corporation, Bedford, MA). Aliquots of 10 µL were taken and sent for microarray analysis.
Label biotin
Label protocol Biotinylated and amplified cRNA was generated using Illumina® TotalPrep RNA Amplification Kit (Applied Biosystems/Ambion, Austin, TX).
 
Hybridization protocol Labeled cRNA samples (750 ng) were then hybridized to MouseRef-8 v2.0 Expression BeadChips (Illumina, Inc., San Diego, CA) in accordance with Illumina’s standard protocols for hybridization, staining, and data acquisition.
Scan protocol BeadChips were imaged using the Illumina BeadArray Reader (Infinium I FastScan scanner protocol), a two-channel 0.8 μm resolution confocal laser scanner. The Illumina BeadScan software (version 3, 2006) was used for the identification of bead positions and the extraction of raw-data.
Description NA
Data processing Raw data (TIFF files) were loaded into the beadarray package (v1.10.0) of the BioConductor open-source library in the R statistical environment (v2.8.1). Following BASH analysis using default settings to mask spatial artefacts data was pre-processed using the Edwards background correction method and normalized using variance-stabilizing normalization as implemented in the vsn package (v3.8.0).
