|
| Source name |
Influenza_Control
|
| Organism |
Mus musculus |
| Characteristics |
mouse strain: C57BL/6
mouse model: Influenza A virus
condition: Control
infection protocol: Influenza A/X-31 (H3N2) strain (a kind gift from Dr J. Skehel, MRC NIMR) was grown in the allantoic cavity of 10 day-embryonated hen’s eggs, stored at -80 °C and titrated on MDCK cells prior to infection. Female C57BL/6/J mice were infected intranasally with 8x103 TCID50 in 30 ml of PBS. Control uninfected mice received PBS only. Lung samples were collected from individual infected and control treated mice on day 6 post infection.
tissue: lung
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Tissues were collected in TRI-Reagent (Sigma-Aldrich) (for Toxoplasma gondii samples –tissues were collected and samples were stored in RNAlater (Ambion), and then transferred to TRI-Reagent). Total RNA was extracted using the RiboPure™ Kit (Ambion).
|
| Label |
biotin
|
| Label protocol |
cRNA was prepared from 200 ng tissue total RNA using the Illumina TotalPrep RNA Amplification Kit (Ambion). Quality was checked using an RNA 6000 Nano kit (Agilent) using a BioAnalyzer 2100 (Agilent). Biotinylated cRNA samples were randomized.

|
| Hybridization protocol |
1.5 µg cRNA was then hybridized to Mouse WG-6 v2.0 bead chips (Illumina) according to the manufacturer’s protocols.
|
| Scan protocol |
Standard Illumina scanning protocol
|
| Description |
raw data file: MRC24.txt
Control samples from Influenza A virus infection model
|
| Data processing |
Microarray data was processed in GeneSpring GX v14.8 (Agilent Technologies). Flags were used to filter out the probe sets that did not result in a ‘present’ call in at least 10% of the samples, with the ‘present’ lower cut-off of 0.99. Signal values were then set to a threshold level of 10, log2 transformed, and per-chip normalised using 75th percentile shift algorithm. Next, per-gene normalisation was applied by dividing each messenger RNA transcript by the median intensity of all the samples. Next, transcripts were filtered to select the most variable probes: those that had a minimum of 1.5-fold expression change compared with the median intensity across all samples, in greater than 10% of all samples.
