Genomic copy number analysis, using array CGH, was performed on murine tumors in order to compare the overlap of copy number alterations between HGSC models and TCGA data. Array CGH was performed on genomic DNA isolated from murine HGSC tumors. Genomic DNA from three normal mouse fallopian tubes was pooled and used as the reference.

In Feature Extraction software, for CGH data, linear normalization method is used. Analysis was performed with Nexus software (BioDiscovery), for identification of copy number alterations. FASST2 segmentation algorithm was applied by setting the following parameters. A minimum number of 5 probes per segment were used to call a copy number aberration with significance threshold of 5x10-6. We used log ratio cut offs of M-BM-10.3 to call one copy gain/loss and M-BM-10.7 to call high gain/ homozygous loss. ID_REF = VALUE = normalized log2 ratio (Cy5/Cy3) representing test/reference Briefly, reference and test DNA were first fragmented using a heat block at 95M-0C for 5 minutes and then labeled using Cyanine3 / Cyanine5 fluorescence labeled nucleotides respectively, according to the BioPrime Array CGH Genomic Labeling protocol (Invitrogen).Labeled DNA was purified using AmiconM-. Ultra-0.5 30k purification columns (Millipore). Test and reference DNA were combined and hybridized to the Agilent 1M mouse catalog array for 40 hours at 65M-0C. The array slides were then washed and scanned. Mouse genomic DNA was isolated using Gentra Puregene Cell Kit (Qiagen) according to the manufacturerM-bM-^@M-^Ys instructions Arrays were scanned using the Agilent G2565AA scanner Protocol Type normalization data transformation protocol labelling protocol hybridization protocol nucleic acid extraction protocol array scanning protocol Experimental Factor Name GENOTYPE Experimental Factor Type genotype Comment[SecondaryAccession] GSE49827 Comment[GEOReleaseDate] 2013-12-17 Comment[ArrayExpressSubmissionDate] 2013-08-13 Comment[GEOLastUpdateDate] 2013-12-17 Comment[AEExperimentType] comparative genomic hybridization by array SDRF File E-GEOD-49827.sdrf.txt
