|
| Treatment protocol |
Muscle tissue from one-year old male B6C57/J mice maintained on ad libitum AIN-93G SD until the end of their life.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was extracted from muscle tissue using 1.0mm glass beads (BioSpec Products, Inc.) in a Precellys 24 Tissue Homogenizer (Bertin Technologies) and Qiagen RNeasy Mini Kits for Fibrous Tissue according to manufacturer's specifications. Quality and quantity of the total RNA was checked with the Agilent 2100 bioanalyzer using RNA 6000 Nano chips.
|
| 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 0.75ug of biotin-labeled cRNA was hybridized at 58 degrees C for 16 hours to Illumina's Sentrix MouseRef-8 v2 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 biotin 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.

| Description |
supplementary file:GEO_Supplementary_file_AS_Muscle 9-14-12
Muscle tissue from one-year old male B6C57/J mice maintained on ad libitum AIN-93G SD until the end of their life.
|
| Data processing |
Data was extracted using the Illumina GenomeStudio software(v1.6.0). Any spots at or below the background were filtered out using an Illumina detection p value of 0.02 and above. The natural log of all remaining scores 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 file.
