|
| Source name |
rat liver from 18month F344
|
| Organism |
Rattus norvegicus |
| Characteristics |
Male F344 rats were obtained from Charles River.
no additional
|
| Treatment protocol |
no treatment
|
| Growth protocol |
Rats were housed at Charles River until 1 week before necropsy. Animal facilities were controlled for temperature (20-24°C) and relative humidity (40-60%), and kept under a 12-h light-dark cycle.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated using the TriReagent procedure (Molecular Research Center, Cincinnati, OH) and the Qiagen Rneasy mini RNA cleanup protocol (Qiagen, Valencia, CA)
|
| Label |
biotin
|
| Label protocol |
Samples were labeled according to the Affymetrix protocol
|
| |
|
| Hybridization protocol |
Samples were hybridized according to the Affymetrix protocol
|
| Scan protocol |
Affymetrix protocol using a GeneChip scanner 3000
|
| Description |
gene expression data from rat liver samples- 6,11,18,24 months old
|
| Data processing |
Affymetrix GeneChip microarray suite software was used for washing and scanning. Expression summaries were calculated using an analysis algorithm adapted from Choe et al. (2005) [PMID: 15693945], in the sequence of "Background correction (MAS5), Quantile normalization (RMA), Perfect match adjustment (MAS5), Median polish (RMA), LOESS normalization.
