Comment[ArrayExpressAccession] E-GEOD-78501 MAGE-TAB Version 1.1 Public Release Date 2016-08-22 Investigation Title Gene expression profiling of genes differentially expressed by oral carcinoma Ca9-22 and SLPI-deficient Ca9-22 (ΔSLPI) cells Comment[Submitted Name] Gene expression profiling of genes differentially expressed by oral carcinoma Ca9-22 and SLPI-deficient Ca9-22 (ΔSLPI) cells Experiment Description We used the myoma model in conjunction with gene expression profiling with microarray data as an efficient tool for high throughput analysis and to screen for differentially expressed genes. Our aim was to identify candidates playing an important role in SLPI and/or MMP-promoted tumor invasion by comparing oral carcinoma Ca9-22 cells, which highly express secretory leukocyte protease inhibitor (SLPI) gene, with SLPI-deficient Ca9-22 cells. In oral carcinoma Ca9-22 and SLPI-deficient Ca9-22 (ΔSLPI) samples, gene expression profiling was performed with the Affymetrix Human Genome U133 Plus 2.0 Array. Two arrays for 2 cell lines were analyzed.

ID_REF = VALUE = RMA signal intensity Biotin-labeled cRNA was synthesized by in vitro transcription using the BioArray high-yield RNA transcript labeling system (ENZO, Farmingdale, NY, USA). Biotin-labeled cRNA was added to the fragmentation buffer (Affymetrix), and was heated for 35 min at 95°C. Fragmented cRNA (10 μg) was hybridized to GeneChip Rice Genome Array. GeneChips were washed and stained in the Affymetrix Fluidics Station 450 (Affymetrix). Ca9-22 cells were obtained from RIKEN BRC (Ibaraki, Japan). SLPI-deficient (Δ) Ca9-22 cells were generated as previously described (Mikami et al. Mol Immunol, 2015). Cells were maintained in α-Minimal Essential Medium (Wako, Tokyo, Japan) containing 10% fetal bovine serum (Japan Bio Serum, Tokyo, Japan) and 1% penicillin-streptomycin (Wako) at 37°C in an atmosphere containing 5% CO2. Total RNA was extracted using RNeasy kits (Qiagen, Valencia, CA, USA) according to the manufacturer's instruction. GeneChips were scanned using the GeneChip scanner 3000 integrated with Affymetrix® Microarray Suitesoftware.
