| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was prepared from tumor cryostat sections using the Trizol method according to the manufacturer's instructions.
|
| Label |
Cy3
|
| Label protocol |
7.5 µg total RNA was labeled with Cy3 dye using the miRVana labeling kit according to the manufacturer's instructions (Ambion).
|
| |
|
| Hybridization protocol |
Hybridization on mirVana miRNA Bioarrays V2 were performed according to the manufacturer’s recommendations (Ambion).
|
| Scan protocol |
Hybridization signals were detected at 532 nm using a GenePix 4000B scanner and quantified by GenePix Pro 4.0 software.
|
| Description |
MiRNA labeling and hybridization on mirVana miRNA Bioarrays V2 were performed according to the manufacturer’s recommendations using 7.5 µg of total RNA and the mirVana miRNA labeling kit.
|
| Data processing |
The signal intensity of each spot was calculated by subtracting the local background from the mean signal. After averaging replicate spots, a global scaling normalization was applied, as suggested by Ambion. This normalization consisted of the following steps: 1) thresholding, for which intensities below the background (set to 2 times the signal of empty spots) were set to 1; 2) scaling, which involved ranking the intensities of each sample separately and dividing them by the 30th intensity value; and 3) log 2 transformation. The normalized intensities were used for further analyses.
