Sample GSM1099600 Query DataSets for GSM1099600
Status Public on Jul 30, 2014
Title cHF+Phospholipids+Rosi, replicate 5
Sample type RNA
 
Channel 1
Source name cHF+Phospholipids+Rosi, replicate 5
Organism Mus musculus
Characteristics strain: C57BL/6N
gender: male
age: adult
tissue: liver
Treatment protocol Animals were fed a control corn oil-based high-fat diet (cHF), or one of the cHF supplementations: 1) ~7 % of dietary lipids was replaced by the EPA and DHA concentrate in the form of omega-3 phospholipids rich in phosphatidylcholine (PC); 2) low dose rosiglitazone (R); and 3) both PC and rosiglitazone (PC+R). All groups received the diet ad-libitum during 7 weeks intervention.
Extracted molecule total RNA
Extraction protocol Total RNA was isolated from liver tissue stored in RNAlater Solution using TRIZol Reagent (Sigma-Aldrich) according to the manufacturer’s instruction. After extraction, RNA was purified by using RNeasy columns (Qiagen). RNA concentration and purity were measured using the NanoDrop spectrophotometer (IsoGen Life Science). The integrity of RNA was checked with Experion automated electrophoresis system (BioRad).
Label Cy5
Label protocol 1,000 ng of purified individual total RNA was used for cDNA synthesis, splitted in two equal fractions and used for subsequent cRNA labeling and synthesis using Cy5 and Cy3 dyes and the Agilent low RNA input fluorescent lineair amplification protocol, as described previously (Van Helden et al., Carcinogenesis 2010).

Hybridization protocol Individual Cy5-labelled samples were hybridized against the Cy3-labelled reference pool according to the manufacturers' procedure using Agilent In Situ Hybridization Kit Plus and GEx Hybridization Buffer HI-RPM. Samples were applied to microarrays enclosed in Agilent SureHyb-enabled hybridization chambers and hybridized at 65C for 17 hours at 10rpm rotation. After hybridization, slides were washed sequential following Agilents' recommendations and finally covered with Ozone-barrier slides.
Scan protocol Scanned with an Agilent Technologies Scanner G2505B with 10 and 100% laser-power intensities.
Description Cy3 samples were pooled on a equimolar basis and served as reference pool, and individual Cy5-labelled samples were hybridized against the reference pool.
Data processing Images were quantified using Agilent Feature Extraction Software (v 10.5.1.1) to obtain raw median signal and background values for both Cy5 and Cy3. Spots with a mean signal higher than twice the background value over all arrays were considered to be expressed. Data was normalized according to Pellis et al., (Physiol Genomics 2003; 16:99-106) based on the Cy3-reference pool, and log2 transformation.
