| Title |
20073017 Adipose 2 Low Gain |
| Sample type |
RNA |
| |
|
| Source name |
Subcutaneous adipose tissue biopsied from the lumbo-sacral fat pad
|
| Organism |
Bos taurus |
| Characteristics |
group: Low Gain
tissue: Subcutaneous adipose
|
| Treatment protocol |
Animals most divergent for gain (6 highes gaining animals, and 6 lowest gaining animals) calculated using data from the ad libitum study, were selected and adipose tissue samples were collected. The adipose transcriptome was evaluated by microarray.
|
| Growth protocol |
Cows (n=121) were placed on a diet to provide 120 kcal ME/kg BW0.75 for 112 days. Adipose was sampled on the 105th day of this trial. Cows were then offered feed ad libitum for 112 days. Adipose tissue was sampled at day 49.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
TriPure Reagent was used to extract total RNA according to manufacturer's instructions, except that a 20 minute centrifugation (rather than 15 min) was used following the addition of chloroform.
|
| Label |
Biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 250 ng total RNA.
|
| |
|
| Hybridization protocol |
Following fragmentation, cRNA was hybridized for 20 hr at 45C on Bovine 1.1ST Array. GeneChips were washed and stained in the Affymetrix GeneAtlas Fluidics Station.
|
| Scan protocol |
GeneChips were scanned with the Affymetrix GeneAtlas Imager.
|
| Data processing |
The data were transformed by Affymetrix and analyzed with Affymetrix Expression Console and Affymetrix Transcriptome Analysis Console using the one-way between-Subject ANOVA (Unpaired) algorithm was (Linear Fold Change cutoff of 2 and ANOVA p-value (Condition pair) <0.05).
