Controls, like healthful blood donors and patients with benign gynecologic diseases, had been collected chronologically at the Healthcare University of Vienna, Austria, for the duration of one year, thus representing a cross-section in the population at danger. All blood samples from epithelial ovarian cancer individuals had been collected within the course on the EU-project OVCAD (Ovarian Cancer Diagnosing a Silent Killer) within two days prior to surgery (Charit?

Total RNA was isolated working with the RNeasy Mini kit (QIAGEN, Venlo, Netherlands) and quality-checked using the Agilent 2100 Bioanalyzer (Agilent Technologies, Santa Clara, Ca, USA). The RNA-quantity was measured spectrophotometrically.Microarray evaluation and pre-selectionWhole genome expression analysis was performed on single channel Applied Biosystems Human Genome Surveymicroarrays V2.0 (Applied Biosystems, Foster City, Ca, USA) containing 32,878 probes rep.
