Epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer (1). We sought to identify genes associated with epithelial ovarian cancer and the high-grade serous ovarian cancer (HGSC) subtype by comparing global gene expression profiles of normal ovary with that of primary tumors from women diagnosed with epithelial cancer and HGSC in specific using published microarray data (2, 3). We identified the gene encoding the baculoviral inhibitor of apoptosis repeat (IAP) containing 5, BIRC5 as among the genes whose expression was most different in epithelial ovarian cancer and in HGSC ovarian tumors. BIRC5 expression was significantly higher in ovarian tumors relative to normal ovary. Correlation of BIRC5 expression with survival outcomes in patients with ovarian cancer was complex, with low expression favorable early in disease and high expression favorable later in disease. These data indicate that expression of BIRC5 is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. BIRC5 may be relevant to pathways underlying ovarian cancer progression.

Epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer (1). We sought to identify genes associated with epithelial ovarian cancer and the high-grade serous ovarian cancer (HGSC) subtype by comparing global gene expression profiles of normal ovary with that of primary tumors from women diagnosed with epithelial cancer and HGSC in specific using published microarray data (2, 3). We identified the gene encoding prepronociceptin, PNOC, as among the genes whose expression was most different in epithelial ovarian cancer and in HGSC ovarian tumors. PNOC expression was significantly higher in high-grade serous ovarian tumors relative to normal ovary. PNOC expression correlated with overall survival in patients with ovarian cancer. These data indicate that expression of PNOC is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. PNOC may be relevant to pathways underlying ovarian cancer progression.

Ovarian cancer is the most lethal gynecologic cancer (1-3). We sought to identify genes associated with high-grade serous ovarian cancer (HGSC) by comparing global gene expression profiles of normal ovary with that of primary tumors from women diagnosed with HGSC using published microarray data (4, 5). We identified paternally expressed gene 3 (PEG3) (6) as among the genes whose expression was most different in HGSC ovarian tumors. PEG3 expression was significantly lower in ovarian tumors relative to normal ovary. In one dataset, an anti-sense transcript produced at the PEG3 locus was among those most differentially expressed between HGSC tumors and benign ovarial tissue. These data indicate that significant changes in expression at the PEG3 imprinted locus could be a feature of high-grade serous ovarian cancers.

Ovarian cancer is the most lethal gynecologic cancer (1). To identify genes associated with high-grade serous ovarian cancer (HGSC), we used published microarray data (2, 3) to compare global gene expression profiles of the normal ovary with that of primary tumors from women diagnosed with HGSC. We identified caspase-12 (CASP12) (4) as among the genes whose expression was most quantitatively different in HGSC ovarian tumors. CASP12 expression was decreased in ovarian tumors when compared to normal ovary. These data indicate that CASP12 might be relevant to the biology of high-grade serous ovarian cancers.

Ovarian cancer is the most lethal gynecologic cancer (1-3). We sought to identify genes associated with high-grade serous ovarian cancer (HGSC) by comparing global gene expression profiles of normal ovary with that of primary tumors from women diagnosed with HGSC using published microarray data (4,5). We identified the chromobox homolog 7 (CBX7) (6) as among the genes whose expression was most different in HGSC ovarian tumors. CBX7 expression was significantly lower in ovarian tumors relative to normal ovary. These data reveal perturbed expression of a tumor suppressor (7) with epigenetic activity at lysine 27 of histone H3 (H3K27) (8) in high-grade serous ovarian cancers.

Ovarian cancer is the most lethal gynecologic cancer (1). We sought to identify genes associated with high-grade serous ovarian cancer (HGSC) by comparing global gene expression profiles of normal ovary with that of primary tumors from women diagnosed with HGSC using published microarray data (2, 3). We identified the forkhead box L2, (FOXL2) (4) as among the genes whose expression was most different in HGSC ovarian tumors. FOXL2 expression was significantly lower in ovarian tumors relative to normal ovary. FOXL2 has established roles in ovarian development (4, 5), and the FOXL2 gene is mutated in granulosa-cell tumors of the ovary (6). These data indicate FOXL2 might also be perturbed, at the level of gene expression, in high-grade serous ovarian cancers.

Epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer (1). We performed discovery of genes associated with epithelial ovarian cancer and of the high-grade serous ovarian cancer (HGSC) subtype, using published microarray data (2, 3) to compare global gene expression profiles of normal ovary or fallopian tube with that of primary tumors from women diagnosed with epithelial ovarian cancer or HGSC. We identified the gene encoding sarcospan, SSPN, as among the genes whose expression was most different in epithelial ovarian cancer as compared to the normal fallopian tube. SSPN expression was significantly lower in high-grade serous ovarian tumors relative to normal fallopian tube. SSPN expression correlated with progression-free survival in patients with ovarian cancer. These data indicate that expression of SSPN is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. SSPN may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.

PDE5A expression was significantly lower in high-grade serous ovarian tumors relative to normal fallopian tube. PDE5A expression correlated with progression-free survival in patients with p53 mutant ovarian cancer. These data indicate that expression of PDE5A is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. PDE5A may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.
