Sample GSM644386 Query DataSets for GSM644386
Status Public on Mar 01, 2011
Title Genotype: PolyQ Atro A75QN, Day: 2, Repl: 3
Sample type RNA
 
Source name Adult flies expressing PolyQ Atro A75QN after 2 days at 29 C
Organism Drosophila melanogaster
Characteristics ageing at 29 c in days: 2
genotype: PolyQ Atro A75QN transgene expressed
Treatment protocol Flies were anesthetised with CO2, decapitated and heads were immediately snap frozen in liquid N2.
Growth protocol Flies were allowed to develop at 18°C, and newly eclosed flies (0-48 hours) were collected and sacrificed immediately (0 days) or aged for 2 or 14 days at 29°C. The fly food used was standard cornmeal supplemented with yeast and molass. For ageing flies were flipped in fresh vials every 48 hours.
Extracted molecule total RNA
Extraction protocol RNA was extracted from 20 fly heads using the RNAgents kit (Promega) according to manifacturer instruction; RNA quantity and quality were assessed by Nanodrop 1000 (Thermo Scientific)
Label biotin
Label protocol The affymetrix protocol was followed for labelling 5ug of total RNA.
 
Hybridization protocol The resulting cRNA was Hybridysed on GeneChip Drosophila Genome Array 2.0. The Genechips were washed and stained in the Affimetrix fluidic station.
Scan protocol GeneChips were scanned at the EMBL Gene Core Facility
Description Replicate 3 for gene expression on log2 scale for adult flies expressing PolyQ Atro A75QN after 2 days of ageing at 29 C
A75QN-d2-33
Data processing The data were normalized using a variance stabilisation protocol on perfect matches only, and summarized using median polish. The algorithms were implemented in Bioconductor 2.8.0, packages vsn (3.16.0) and affy (1.26.1), on a machine running R 2.11.0 compiled for x86_64-apple-darwin9.8.0
