| Title |
Tryptophan benzyl ester-betaxanthin treated JK1466 animals, Independent Trial 3 |
| Sample type |
RNA |
| |
|
| Source name |
C. elegans JK1466 treated with 25 uM Tryptophan benzyl ester-betaxanthin
|
| Organism |
Caenorhabditis elegans |
| Characteristics |
tissue: Whole animal
genotype: Jk1466 (gld-1(-))
age: 2 days after hacht, L4/young adults
|
| Treatment protocol |
16-18 hours after haching L1 larvae were treated with 25 uM of each tryptophan derived-betaxanthin in S. medium for 48 hours at 20 ºC
|
| Growth protocol |
JK1466 worms were syncronized using the bleaching protocol, from adult worms maintained in standart NGM agar plates at 20 ºC
|
| Extracted molecule |
total RNA |
| Extraction protocol |
TRIzol extraction of total RNA was performed according to the manufacturer's instructions, followed by a purification using PureLink TM RNA Mini Kit from Invitrogen
|
| Label |
BIOTIN-STREPTAVIDIN
|
| Label protocol |
Ss-cDNA was synthetized from 3.5 ng of each sample using the GeneChip WT Pico Reagent kit (Affymetrix, P/N 703262). The amount and quality of ss-cDNA were checked by Nanodrop and Bioanalyzer. ss-cDNA targets were cleaned up, and after fragmentation and terminal labelling with biotin

|
| Hybridization protocol |
3.75 µg of fragmented and biotinylated ss-cDNA were included in the hybridization mix, using the GenAtlas Hybridization, Wash and Stain kit for WT Array Strips (Affymetrix, P/N 901667) according to the recommendations of the manufacturer. The resulting preparations were hybridized to GeneChip® C. elegans Gene 1.1 ST Array Strip (Affymetrix, 902157) with 26 unique sequences of each transcript. After applying hybridization (spike controls) and labeling tests it was observed that the 20 chips had fulfilled the quality criteria.

| Data processing |
After scanning, microarrays data were processed using Affymetrix Expression Command Console (Affymetrix) and all samples were within bounds for hybridization and labeling tests. Three independent RNA samples were employed. Samples from worms treated with food colorants were grouped as “treatment” and worms with no exposition were grouped as “control”. Data analysis was then performed with RMA (Robust Multiarray Average) allowing raw intensity values to be background corrected, log2 transformed and then quantile normalized in order to obtain an individual intensity value for each probe set.
