Publication protocol

total RNA was isolated from the Fallopian tube tissue using Trizol (Invitrogen, Carlsbad, CA, USA), according to the manufacturer's instructions, followed by DNase treatment. The purity and quality of the RNA were assessed spectrophotometrically by determining their absorbance ratio A260/A280 and electrophoresis of samples on 1.5% denaturing agarose gels. First and second-strand cDNA were prepared according to the Affymetrix microarray preparation protocol. Biotinylated-cRNA was then prepared using a BioArray High Yield T7 Transcript labelling kit (Enzo, Farmingdale, NY, USA) and chemically fragmented. Biotinylated cRNAs were hybridized overnight to a high-density Affimetrix Human Genome U133 Plus 2.0 oligonucleotide microarray genechip containing 54,600 probe sets (42,203 annotated genes and 12,397 expressed sequence tags (EST)) at the Stanford University School of Medicine Protein and Nucleic Acid Facility. Subsequently, fluorescent labelling and laser confocal scanning with an HR 3000 scanner was conducted. Generated data were extracted for analysis using the Affymetrix Gene-Chip Operating Software (GCOS) version 1.1.
