|
| Treatment protocol |
Samples were OCT-embedded and frozen before RNA extraction
|
| Growth protocol |
Biopsies of oral leukoplakia
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was extracted and purified from OCT-embedded tissue using the RNeasy Mini Kit (Qiagen) including on-column DNase (Qiagen) digestion as described by the manufacturer's protocol.
|
| Label |
biotin
|
| Label protocol |
WT-Ovation™ Pico products (NuGEN) are labeled using the FL-Ovation™ cDNA Biotin Module V2 (NuGEN). Each labeled cRNA targets are synthesized according to manufacturer's protocols.
|
| |
|
| Hybridization protocol |
Hybridization mixtures were prepared according to Affymetrix procedures to accommodate 5 μg of cDNA targets from NuGEN amplification. Human Gene 1.ST platform were hybridized, revealed and washed according to the Affymetrix protocol.
|
| Scan protocol |
Gene chips were scanned using a 7 G scanner (Affymetrix) and images (DAT files) were converted to CEL files using GCOS software (Affymetrix).

| Description |
RNA was extracted and purified from OCT-embedded tissue using the RNeasy Mini Kit (Qiagen) including on-column DNase (Qiagen) digestion as described by the manufacturer's protocol. RNA amplifications were performed using the WT-Amplification™ Pico (NuGEN) kit. For all experiments, the manufacturers' protocols were strictly followed. WT-Ovation™ Pico products (NuGEN) are labeled using the FL-Ovation™ cDNA Biotin Module V2 (NuGEN). Each labeled cRNA targets are synthesized according to manufacturer's protocols. The quantity and quality of the amplified cRNA or cDNA were assessed by a ND-1000 spectrophotometer (Nanodrop Technologies), and Agilent Bioanalyzer (Agilent Technologies), respectively. Hybridization mixtures were prepared according to Affymetrix procedures to accommodate 5 μg of cDNA targets from NuGEN amplification. Human Gene 1.ST platform were hybridized, revealed and washed according to the Affymetrix protocol. Gene chips were scanned using a 7 G scanner (Affymetrix) and images (DAT files) were converted to CEL files using GCOS software (Affymetrix).
|
| Data processing |
Raw data of microarrays were processed using quantile normalization and RMA algorithm (RMAExpress); expression values were log2 transformed
