| Title |
Rat retina_Saffron_ rep3 |
| Sample type |
RNA |
| |
|
| Source name |
retina, pretreatment saffron, 1mg/kg/day for 3 weeks
|
| Organism |
Rattus norvegicus |
| Characteristics |
strain: Sprague Dawley
tissue: retina
developmental stage: Adult P80 - 120
|
| Treatment protocol |
Animals were fed saffron at 1mg/kg/day, for 3w. Saffron (stigmata of Crocus sativus, from the Abbruzzo region in Italy) was soaked in water (at 2mg of spice/ml H2O) and 12h was allowed for the major anti-oxidants, which are water-soluble, to dissolve fully. The solute was then fed to the rats injecting a small volume into a piece of the vegetable matrix, which the animal readily ingested. The volume for each daily feed was calculated to provide the solutes from 1mg of saffron/kg body weight. Tissue was collected 24h after the last feed.
|
| Growth protocol |
All animals were raised in 5 lux cyclic light. They were routinely fed a vegetable (potato or rice) matrix, developed as a biodegradable packaging material, and we used the same matrix used as vehicle for feeding them with saffron.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted from each retinal biopsy using Trizol and chloroform to separate the RNA from other cell components. The RNA was then purified and isolated using RNAqueous-Micro RNA isolation kit (Ambion, Inc., Austin, TX). In some cases where genomic DNA contamination was a concern, the RNA was DNAse treated.
|
| Label |
Biotin
|
| Label protocol |
Biotin-labeled cRNA was prepared according to the standard Affymetrix protocol from 1 ug total RNA (GeneChip® Whole Transcript (WT) Sense Target Labeling Assay 2009, Affymetrix, Inc.).
|
| |
|
| Hybridization protocol |
Standard Affymetrix protocols were followed in the hybridisation, blocking and washing (GeneChip® Expression Wash, Stain and Scan User Manual (P/N 702731)).
|
| Scan protocol |
Image analysis was performed using the standard Affymetrix protocols (GeneChip® Expression Wash, Stain and Scan User Manual (P/N 702731)). Scanning was performed using the GeneChip® Scanner 3000 and Affymetrix® GeneChip® Command Console® (AGCC).
|
| Description |
Gene expression data from rat retina exposued to normal light levels and 3 weeks of 1mg/kg/day of saffron.
|
| Data processing |
RMA expression values, log transformed (base 2) using Expression console (version 1.1.2800.19935). Normalized data were analyzed using GeneSpring GX v10 software.
