Sample GSM3101204 Query DataSets for GSM3101204
Status Public on May 09, 2018
Title colon, control diet, age 24 months, rep15
Sample type RNA
 
Source name scraping from colonic mucosa and submucosa, control diet, age 24 months
Organism Mus musculus
Characteristics Sex: male
mouseid: A3_15
diet group: C
diet (full name): control
age at sacrifice (months): 24M
mouse number: 15
tissue: colon
strain: C57BL/6J
Treatment protocol Prior to sacrifice, each mouse was first fasted for 4 hours after which they received an intragastric gavage of 400ul of 0.5% carboxymethyl cellulose, then fasted again for another 6 hours. During the sacrifice, after sedation with a mixture of isoflurane (1.5%), nitrous oxide (70%) and oxygen (30%), colon tissue was removed, whereafter the mucosa and submucosa was scraped-off, snap-frozen and stored at -80C until further analysis.
Growth protocol The design of the study and experimental procedures have been described in detail previously (PMID: 25504628). Briefly, male C57BL/6J mice (age: 7 weeks) were purchased from Janvier (Cedex, France) and were housed in pairs of two in the light and temperature (20C)-controlled animal facility of Wageningen University (12-hour light/dark cycle, lights on at 04.00). The mice received standard AIN-93G (Research Diet Services, Wijk bij Duurstede, The Netherlands) for 2 weeks upon arrival. At the age of 9 weeks, mice were individually housed and randomized to different dietary regimens. For the current analyses, we only considered mice that were lifelong fed ad libitum a semi-synthetic control diet consisting of 10E% of fat (C; control). Mice were sacrificed at 6, 12, 24 or 28 months of age.
Extracted molecule total RNA
Extraction protocol Total RNA was isolated from the scrapings using TRIzol Reagent according to the manufacturer’s instructions (Invitrogen, Breda, The Netherlands). Isolated RNA was purified using RNeasy Micro columns (Qiagen, Venlo, The Netherlands) and total RNA yield (Nanodrop ND-1000, Nanodrop Products, Maarssen, The Netherlands) and RNA integrity (Agilent 2100 Bioanalyzer, Agilent Technologies, Amsterdam, The Netherlands) were assessed. RNA was judged as suitable for array hybridization only if samples exhibited intact bands corresponding to the 18S and 28S ribosomal RNA subunits, and displayed no chromosomal peaks or RNA degradation products (RNA Integrity Number > 8.0).
Label biotin
Label protocol Purified total RNA (100ng per sample) was labeled with the Whole-Transcript Sense Target Assay (Affymetrix, Santa Clara, CA, USA; P/N 900652).
 
Hybridization protocol Hybridization and washing of the Affymetrix GeneChip Mouse Gene 1.1 ST peg arrays were performed on a GeneTitan Instrument (Affymetrix, Santa Clara, CA) according to the manufacturer's recommendations.
Scan protocol Arrays were scanned on an Affymetrix GeneTitan instrument (Affymetrix, Santa Clara, CA).
Data processing Expression estimates were calculated applying the RMA algorithm in the Bioconductor library 'Oligo' (v1.42.0).
