| Label protocol |
250 ng total RNA was used to prepare biotinylated aRNA (cRNA) according to the manufacturer’s protocol (Affymetrix 3’ IVT Express Kit). Briefly, total RNA undergoes T7 oligo(dT)-primed reverse transcription to synthesize first-strand cDNA containing a T7 promoter sequence. This cDNA is then converted into a double-stranded DNA template for transcription using DNA Polymerase and RNase H to simultaneously degrade the RNA and synthesize second strand cDNA. In vitro transcription synthesizes aRNA and incorporates a biotin-conjugated nucleotide. The aRNA is then purified to remove unincorporated NTPs, salts, enzymes, and inorganic phosphate. Fragmentation of the biotin-labeled aRNA prepares the sample for hybridization onto GeneChip 3’ expression arrays.

| Hybridization protocol |
Samples were prepared for hybridization using 12.5 µg of biotinylated aRNA in a 1X hybridization cocktail according the Affymetrix hybridization manual. Additional hybridization cocktail components were provided in the Affymetrix GeneChip Hybridization, Wash and Stain Kit. GeneChip arrays were hybridized in a GeneChip Hybridization Oven at 45°C for 16 hours at 60 RPM. Washing was done using a GeneChip Fluidics Station 450 according to the manufacturer’s instructions, using the buffers provided in the Affymetrix GeneChip Hybridization, Wash and Stain Kit.
|
| Scan protocol |
Arrays were scanned on a GeneChip Scanner 3000 and images were extracted with Affymetrix GeneChip Command Console (AGCC), and analyzed using GeneChip Expression Console.

| Description |
Gene expression data of the indicated cell line
|
| Data processing |
The data were analyzed with Affy Expression Console software, using RMA method. Probes were further filtered to include only probes that have at least one call > 6 (in log2-scale)
