| Title |
Rat retina_Light Damage_ rep1 |
| Sample type |
RNA |
| |
|
| Source name |
retina, exposed to 24hrs 100lux light
|
| Organism |
Rattus norvegicus |
| Characteristics |
strain: Sprague Dawley
tissue: retina
developmental stage: Adult P80 - 120
|
| Treatment protocol |
The animals were kept individually in plexiglass cages, with food kept on the floor of the cages and water offered from transparent containers, to ensure uniform exposure. After overnight dark adaptation, animals were exposed to bright (1000 lux) light for 24h, from a white fluorescent source. Exposure began and ended at 9.00am.
|
| 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. Animals were raised in normal 5lux light before being exposued to damaging 1000lux light for 24 hrs.
|
| 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.
