SignificanceThere is an unmet need for effective ovarian cancer screening and diagnostic approaches that enable earlier-stage cancer detection and increased overall survival. We have developed a high-performing accessible approach that eval…

Endometrioid and mucinous ovarian carcinomas represent nearly a fifth of ovarian cancers, but their molecular characteristics and pathologic origins are poorly understood. To identify the genomic and epigenomic alterations characteristic of…

Kaplan-Meier survival curves for ovarian cancer patients with and without mutations in the PI3K and WNT pathways. (a, b) Alterations in the PI3K pathway trended towards increased survival among patients with ovarian endometrioid carcinomas …

Epigenetic aberrations, including posttranslational modifications of core histones, are major contributors to cancer. Here, we define the status of histone H2B monoubiquitylation (H2Bub1) in clear cell ovarian carcinoma (CCOC), low-grade se…

Exome sequencing of ovarian clear-cell carcinoma has identified somatic mutations in PPP2R1A, a subunit of protein phosphatase 2A. The present study was performed to determine the frequency of PPP2R1A mutations in exon 5, which harbors prev…

Ovarian clear cell carcinoma (OCCC) is an aggressive human cancer that is generally resistant to therapy. To explore the genetic origin of OCCC, we determined the exomic sequences of eight tumors after immunoaffinity purification of cancer …

Ovarian clear cell carcinoma (CCC) is one of the most malignant types of ovarian carcinomas, particularly at advanced stages. Unlike the more common type of ovarian cancer, high-grade serous carcinoma, ovarian CCC is often resistant to plat…
