|
| Source name |
head of pancreas
|
| Organism |
Homo sapiens |
| Characteristics |
tissue: pancreatic tumor
Stage: 4
grouped stage: Advanced
|
| Biomaterial provider |
Baki Topal (Department of Abdominal Surgical Oncology, University Hospitals Leuven, KU Leuven)
|
| Treatment protocol |
NA
|
| Growth protocol |
Snap-frozen tissue samples were stored in liquid nitrogen and/or at -80C in RNALater (Qiagen) until further use.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
total RNA was extracted using the RNeasy Mini kit (Qiagen) according the manufacturer's instructions. Only samples with an RNA integrity number (RIN) of >7.0 were used.
|
| Label |
biotin
|
| Label protocol |
RNA concentration and purity were determined spectrophotometrically using the NanoDrop ND-1000 (NanoDrop Technologies), and RNA integrity was assessed using a Bioanalyser 2100 (Agilent). Using the NuGEN Ovation Pico WTA System, an amount of 2 ng of total RNA was amplified and converted to cDNA. An amount of 5 ug of cDNA was fragmented and labeled with biotin using the NuGEN Encore Biotin Module.

| |
|
| Hybridization protocol |
A mixture of fragmented biotinylated cDNA and hybridisation controls (Affymetrix) was hybridised on Affymetrix HG U219 arrays, followed by staining and washing in a GeneChip Fluidics Station 450 (Affymetrix) according to the manufacturer's procedures.
|
| Scan protocol |
To assess the raw probe signal intensities, chips were scanned using a GeneChip Scanner 3000 (Affymetrix).

| Description |
PDAC
|
| Data processing |
Data were normalized using RMA as implemented in the xps package of Bioconductor. Expression values are represented on a log2-scale.
