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 previously identified forkhead box L2 (4), (FOXL2) as among the genes whose expression was most different in HGSC ovarian tumors when compared to the ovary. Here, we find that potential FOXL2 transcriptional target (5,6) odd-skipped related gene OSR2 (7) is differentially expressed in high-grade serous ovarian cancer, and could be observed in independent tumor microarray data (2,3). These data reveal perturbed expression of a target gene of a key transcription factor and specifier of ovarian cell fate 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). Perturbed expression of TCEAL7 has previously been reported in epithelial ovarian cancers (4). Here we find significant differential expression of multiple members of the TCEAL gene family in high-grade serous ovarian tumors.

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.

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 and public 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 SLIT and NTRK-like family member 3, SLITRK3, as among the genes whose expression was most different in epithelial ovarian cancer as compared to the normal fallopian tube. SLITRK3 expression was significantly lower in high-grade serous ovarian tumors relative to normal fallopian tube. SLITRK3 expression correlated with progression-free survival in patients with ovarian cancer. These data indicate that expression of SLITRK3 is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. SLITRK3 may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.

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.

MRVI1 expression was significantly lower in high-grade serous ovarian tumors relative to normal fallopian tube. MRVI1 expression correlated with overall survival in patients with ovarian cancer. These data indicate that expression of MRVI1 is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. MRVI1 may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.
