| Title |
SD-2 |
| Sample type |
RNA |
| |
|
| Source name |
Mus musculus liver tissue
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57BL/6J, Gender: Male, Tissue: Liver, Age: 82weeks
|
| Treatment protocol |
Starting at 56 weeks of age, fed a standard AIN-93G dirt, (SD).
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was extracted using Qiagen RNAeasy Mini kit
|
| Label |
Streptavidin-Cy3 bound to biotin-labeled cRNA.
|
| Label protocol |
standard Illumina protocol using Illumina TotalPrep RNA Amplification Kit (Ambion; Austin, TX, cat # IL1791) In short, 0.5g of total RNA was first converted into single-stranded cDNA with reverse transcriptase using an oligo-dT primer containing the T7 RNA polymerase promoter site and then copied to produce double-stranded cDNA molecules. The double stranded cDNA was cleaned and concentrated with the supplied columns and used in an overnight in-vitro transcription reaction where single-stranded RNA (cRNA) was generated and labeled by incorporation of biotin-16-UTP.

|
| Hybridization protocol |
standard Illumina protocol. In short, a total of 0.75?g of biotin-labeled cRNA was hybridized at 58 degrees C for 16 hours to Illumina's Sentrix MouseRef-8 Expression BeadChips (Illumina, San Diego, CA). Each BeadChip has 24,000 well-annotated RefSeq transcripts with approximately 30-fold redundancy. The arrays were washed, blocked and the labeled cRNA was detected by staining with streptavidin-Cy3.
|
| Scan protocol |
Arrays were scanned at a resolution of 0.8um using the Beadstation 500 X from Illumina.

|
| Data processing |
Data was extracted using the Illumina BeadStudio software(v1). Any spots at or below the background were filtered out using an Illumina detection p-value score of 0.02 and above. The natural log of all remaining genes were used to find the avg and std of each array and the z-score normalization was calculated and presented below. Z-score = (raw value - avg)/std. Complete data including detection scores will be included in the supplemental files.
