RNA of 12 human CCOC cell lines, 10 human CCOC specimen and 10 normal ovarian surface epithelium specimen were extracted and microarray analysis was performed as described protocol [12 (link)]. In brief, following a single strand reverse transcriptase and amplification step, samples were hybridized to Affymetrix U133 Plus 2.0 microarrays. Class comparison in BRB ArrayTools version 3.2.2 software was utilized to identify differentially expressed genes.
