the RNA was analyzed on an Agilent 2100 BioAnalyzer using the RNA6000 labchip kit (Agilent Technologies, Palo Alto, CA). Biotin-labeled antisense cRNA was generated by labeling 20 or 2 μg of total RNA with the BioArray High Yield RNA transcription labeling kit (ENZO) or the Affymetrix Eukaryotic One-Cycle Target Labeling and Control Reagent package, respectively. The quality of the cRNA was checked using the Agilent 2100 bioanalyzer. The labeled cRNA was hybridized to Affymetrix A. niger Genechips. Absolute values of expression were calculated from the scanned array using the Affymetrix GCOS software after an automated process of washing and staining. Microarray Suite Affymetrix v5.1 (Affymatrix Inc., Santa Clara, CA), Spotfire DecisionSite (Spotfire Inc, Somerville, MA), https://www.selleckchem.com/products/nct-501.html GeneData Expressionist Analyst V Pro 2.0.18 (GeneData, Basel, Switzerland) and the R statistical environment http://www.r-cran.org were used for data analyses.
