| Title |
Canton S, wildtype, whole brain, old rep4 |
| Sample type |
RNA |
| |
|
| Source name |
Drosophila adult_Canton S, wildtype, whole brain, old
|
| Organism |
Drosophila melanogaster |
| Characteristics |
gender: female and male
developmental stage: adult
genetic background: Canton S
genotype/variation: WT_old
tissue: brain
|
| Treatment protocol |
Brains were dissected under PBS and transferred directly to a chilled tube containing RNA lysis buffer.
|
| Growth protocol |
All flies were raised and maintained on standard cornmeal molasses agar at 16˚C or room temperature.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was isolated using Ambion RNAqueous Micro columns and amplified using the NuGEN Ovation FFPE WTA System V3.
|
| Label |
biotin
|
| Label protocol |
Biotinylated cRNA were prepared using the NuGEN Encore Biotin Module kit from 3.5ug amplified RNA.
|
| |
|
| Hybridization protocol |
The entire fragmented, labeled cDNA fraction was placed into a hyb cocktail volume of 150uL; 130uL were hybridized for 18-20 hr at 45C on GeneChip Drosophila Genome 2.0 Arrays. GeneChips were washed and stained in the Affymetrix Fluidics Station 450.
|
| Scan protocol |
GeneChips were scanned using the Affymetrix GCS3000 scanner.
|
| Description |
WT_old_4
4 brains total containing both male and female flies
amplified total RNA
|
| Data processing |
Using the R package affy, raw data was processed using RMA. P/M/A calls were extracted using affy, and probes were kept for statistical analyses if greater than 50% of replicates in at least one sample were called present. Of the 18,952 total probes, 13,290 were used for statistical analyses. Differentially expressed genes were determined using the R package limma with an FDR-adjusted p-value of 0.05 as the cutoff for determining statistical significance. Given the presence of batch effects and genetic background effects, we took the lists of differentially expressed genes for WT_new/C17 and WT_new/PMdr65 and subtracted genes that also showed up in the lists of differentially expressed genes between WT_new/WT_old and WT_new/UAS_control.
