| Title |
pancreatic cancer saliva-6 |
| Sample type |
RNA |
| |
|
| Source name |
saliva
|
| Organism |
Homo sapiens |
| Characteristics |
early pancreatic cancer
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Twelve pancreatic cancer samples and 12 matched control samples were used for salivary transcriptome profiling. RNA was isolated from 330 mL of saliva supernatant using the MagMAX Viral RNA Isolation Kit (Ambion). This process was automated using KingFisher mL technology (Thermo Fisher Scientific Inc.), followed by TURBO™ DNase treatment (Ambion). Eluted 10 mL RNA was reserved for subsequent quantitative real-time polymerase chain reaction (qPCR) validation. The remaining RNA (90 mL) was concentrated to 11 mL and then linearly amplified using the RiboAmp RNA Amplification kit (Molecular Devices, Sunnyvale, CA).
After purification, cDNA was in vitro transcribed and biotinylated using GeneChip Expression 3’-Amplification Reagents for in vitro transcription labeling (Affymetrix, Santa Clara, CA).

| Data processing |
The CEL files from all datasets (array data from 12 pancreatic cancer saliva samples and 12 healthy saliva samples) were imported into Affymetrix® Expression Console™ Software. The analysis was performed as follows: the PLIER expression measures were computed after background correction and quantile normalization for each microarray dataset. Probeset-level quantile normalization was performed across all samples to make the effect sizes similar among all datasets.
