Title |
caffeine+ 2 |
Sample type |
RNA |
|
|
Source name |
granulocytes treated with caffeine
|
Organism |
Mus musculus |
Characteristics |
strain: C57BL/6J cell type: granulocytes
|
Treatment protocol |
Cells were plated at a density of 3x105 cells per ml in two different tissue culture plates. The optimal concentration of caffeine (15 mM) was added to the culture medium for 4 hours before cells were washed twice with PBS. Actinomycin D (2 μg/ml) together with caffeine was then added into one plate whereas only actinomycin D was added to the other to block transcription of genes. After an additional 4 hours incubation, total RNA was collected and used for microarray analysis.
|
Extracted molecule |
total RNA |
Extraction protocol |
Trizol extraction of total RNA was performed according to the manufacturer's instructions.
|
Label |
Biotin
|
Label protocol |
Biotinylated cDNA were prepared according to the Encore Biotin Module (Nugen) from 300 ng total RNA.
|
|
|
Hybridization protocol |
Following fragmentation, samples were injected into Affymetrix array chips and hybridized at 45°C and 60 rpm for 17 hours in a hybridization oven (Affymetrix). GeneChips were stained and washed in the Affymetrix GeneChip Fluidic Station 450
|
Scan protocol |
GeneChips were scanned using Affymetrix GeneChip Scanner 3000 7G
|
Data processing |
The data was analysed using R with the RUV procedure described in http://statistics.berkeley.edu/tech-reports/800 for scaling and normalization.
