Sample GSM1180584 Query DataSets for GSM1180584
Status Public on Apr 17, 2014
Title STAP-2-/-, biological rep2
Sample type RNA
Source name DSS-treated colons derived from STAP-2-/- mice
Organism Mus musculus
Characteristics strain/background: C57BL/6J
genotype/variation: STAP-2-/-
age: fourteen weeks
tissue: colon
treatment: DSS
Treatment protocol Wild type (WT) and STAP-2-/- mice were administered 1.75% DSS for 3 days and sacrificed to isolate mRNA from colon tissue.
Extracted molecule total RNA
Extraction protocol Total RNA of the entire colon tissues, which was immediately stored in RNAlater solution at -80 °C (Life Technologies, Carlsbad, CA), was purified using TissueLyser at 20 Hz and RNeasy kit (QIAGEN, Venlo, Netherlands) according to the manufacturer's instructions.
Label Cy3
Label protocol One hundred nanogram of total RNA with spike-in controls using an Agilent One Color Spike Mix Kit (Agilent Technologies) was reverse transcribed into double strand cDNAs by AffinityScript multiple temperature reverse transcriptase and amplified for 2 h at 40°C. Resulting cDNAs were subsequently used for in vitro transcription by T7-polymerase and labeled with cyanine-3-labeled cytosine triphosphate (Perkin Elmer) for 2 h at 40°C using a Low Input Quick-Amp Labeling Kit ver. 6.5 (Agilent Technologies) according to the manufacturer's protocol.
Hybridization protocol After labeling, rates of dye incorporation and quantification were measured with a Nanodrop ND-1000 spectrophotometer (Thermo Scientific) and were then fragmented for 30 min at 60°C in the dark. The labeled 1,650 ng of each cRNA sample was then hybridized on Agilent 4 × 44K whole mouse genome arrays (Agilent Design #026655) at 65°C for 17 h with rotation in the dark. Hybridization was performed using a Gene Expression Hybridization Kit (Agilent Technologies) following the manufacturer's instructions.
Scan protocol After washing in GE washing buffer, slides were scanned with an Agilent Microarray Scanner G2505C.
Description KO2
Acute colitis model was induced to STAP-2-/- mice by addition of 1.75% DSS in drinking water for 7 days.
Pool from 3 mice.
Data processing Feature Extraction software (Version employing defaults for all parameters was used to convert images into gene expression data. Raw data were imported into GeneSpring GX 12.0 (Agilent Technologies) for database management and quality control. For normalization in GeneSpring, the threshold raw signal was set to 1.0 and the global normalization algorithm (percentile shift) was used with a percentile target of 75. This normalized data was used for identifying differentially expressed genes, in which KO group were compared to WT group as control.
