Sample GSM805246 Query DataSets for GSM805246
Status Public on Sep 15, 2013
Title jejunum_Casp1KO_repl3
Sample type RNA
 
Source name jejunum from Caspase-1 null mouse, maintained on chow, 2hrs after lipid load, replicate 3
Organism Mus musculus
Characteristics strain: C57BL/6
genotype/variation: Caspase-1 null
gender: male
tissue: jejunum
age: 14-16 wks
sample type: scraped off epithelial cells, 2hrs after oral lipid load
Treatment protocol Animals were maintained on regular lab chow. Mice were used at age between 14-16 weeks. For sampling of liver tissue, mice were fasted over night (16hrs). For sampling of small intestine, overnight fasted mice first received an intragastric load of 200 µL olive oil (Carbonell, Cordoba, Spain), and 2 hrs later small intestines were removed. The small intestine was subsequently divided into duodenum, jejunum, and ileum, and the epithelial cell layer was scraped off. All tissue samples were immediately snap-frozen in liquid nitrogen and stored at -80°C for RNA isolation.
Growth protocol Caspase-1 null mice were backcrossed ten generations to C57Bl/6 mice and age-matched wild-type C57Bl/6J mice were used as control mice. Mice were housed under standard conditions with a 12-hour light-dark cycle and were fed a standard mouse chow diet with free access to water. Experiments were performed in 14 to 16-week old animals.
Extracted molecule total RNA
Extraction protocol Total RNA was obtained by extraction with TRIzol reagent (Invitrogen, Carlsbad, CA), followed by DNAse treatment and column purification using the RNeasy mini kit (Qiagen, Hilden, Germany). RNA integrity was checked on an Agilent 2100 Bioanalyzer (Agilent Technologies, Amsterdam, The Netherlands) with 6000 Nano Chips. RNA was judged as suitable only if samples showed intact bands of 18S and 28S ribosomal RNA subunits, displayed no chromosomal peaks or RNA degradation products, and had a RNA integrity number (RIN) above 8.0.
Label biotin
Label protocol The Ambion WT Expression kit (Life Technologies, Carlsbad, CA; P/N 4411974) in conjunction with the Affymetrix GeneChip WT Terminal Labeling kit (Affymetrix, Santa Clara, CA; P/N 900671) was used for the preparation of labeled cDNA from 100ng of total RNA without rRNA reduction.
 
Hybridization protocol The Affymetrix GeneChip Mouse Gene 1.1 ST arrays are peg arrays arranged into the standard 96 well plate format. The 24 arrays that were used in this experiment were provided as 1x24 array plate. Array hybridization, washing and scanning were performed on a GeneTitan Instrument according to the manufacturer’s recommendations.
Scan protocol Arrays were scanned on an Affymetrix GeneTitan instrument.
Data processing Expression estimates were calculated applying the RMA algorithm in the Bioconductor library 'Oligo' (v1.16.0). The SI samples were normalzed together, separately from the liver samples.
