Title |
BRN2_HOM_TUM_2 |
Sample type |
RNA |
|
|
Source name |
Primary tumor
|
Organism |
Mus musculus |
Characteristics |
genotype: Tyr::CreErT2::BrafV600E F/+ Pten F/+ BRN2 F/F Sex: female rin: 8.7 category: Braf-Pten-Brn2-hom mouseid: 19A-21-22-28 1442
|
Growth protocol |
Newborn mice were treated dorsally with 0.4 μg/day/mouse tamoxifen from P1 to P3. Developing skin excrescences > 3 mm diameter were considered to be melanomas, and validated after growth. Mice were sacrificed and autopsied four weeks after tumor appearance or once the tumors reached 2 cm3. Only melanoma having a volume of 1cm^3 were used for the transcriptomic analysis. For mice harbouring multiple melanome, only the biggest melanomas on each mouse was harvested. Tumors were then excised, rinsed in cold PBS and snap-frozen in liquid nitrogen.
|
Extracted molecule |
total RNA |
Extraction protocol |
total RNA was extracted using the miRneasy, Qiagen extraction kit according to the manufacturer's instructions.
|
Label |
biotin
|
Label protocol |
The IVT reaction was carried out in the presence of T7 RNA polymerase and a biotinylated nucleotide analog/ribonucleotide mix for cRNA amplification and biotin labelling.
|
|
|
Hybridization protocol |
Complementary RNA (cRNA) was synthesized using the GeneChip 3′IVT Plus reagent Kit, according to the manufacturer’s protocol. Then 11μg cRNA were hybridized to mouse MOE430 gene expression Affymetrix microarrays
|
Scan protocol |
After washing and staining, using the Affymetrix fluidics station 450, the probe arrays were scanned using an Affymetrix GeneChip Scanner 3000.
|
Data processing |
Data processing was done using R/Bioconductor. CEL files were read using the oligo package and normalized using the RMA - Robust Multichip Average algorithm. The highest-IQR probe for each gene was retained.
