Sample GSM627961 Query DataSets for GSM627961
Status Public on Feb 05, 2016
Title R. hominis 28d-AC, rep3
Sample type RNA
 
Source name Mouse ascending colon, 28d after colonization, R. hominis
Organism Mus musculus
Characteristics strain: C3H/HeN
gender: male
tissue: ascending colon
condition: Roseburia hominis colonization
time: 28 days post-colonization
Treatment protocol GF male mice were gavaged at 0d with 100 uL of R. hominis culture. All mice were sacrificed on 14d and 28d post-colonization in parallel to age-matched GF controls.
Growth protocol C3H/HeN mice were bred at the INRA facilities in Jouy-en-Josas. Germ-free (GF) mice were maintained in plastic isolators and fed ad libitum on a commercial diet (R03-40; UAR) sterilized by γ-irradiation (40 kGy).
Extracted molecule total RNA
Extraction protocol Ileal and ascending colon tissue was excised, processed in ice-cold PBS, transferred to RNAlater (Ambion) and stored at -20 °C. Tissue was removed from RNAlater, lyzed in Trizol (Invitrogen), and RNA was extracted using chloroform/isopropanol steps. Total RNA was further treated with the RNeasy kit (Qiagen) according to the manufacturer’s instructions, including an RNase-free DNase I (Qiagen) digestion step.
Label biotin
Label protocol Fragmented and biotin-labelled cRNA was synthesized from 8 ug purified RNA using the One-Cycle Target Labeling Kit (Affymetrix) according to the manufacturer's protocol.
 
Hybridization protocol Following fragmentation, 15 ug of cRNA were hybridized for 16 hr at 45C on a GeneChip NuGO Mouse Array (NuGO_Mm1a520177). GeneChips were washed and stained in the Affymetrix Fluidics Station.
Scan protocol GeneChips were scanned using the Hewlett-Packard GeneArray Scanner.
Description Rh8-AC
Data processing Initial data analysis was performed using Affymetrix GCOS 1.2 software. Data were further analyzed using Bioconductor (http://www.bioconductor.org) from the R Project for Statistical Computing (http://www.r-project.org). Normalization was performed with gcRMA. The moderated t-test provided by the Bioconductor package limma was used to test for differential expression. Data was considered significant when P<0.05 using the Benjamini and Hochberg false discovery method.
