UNLABELLED: Clear cell ovarian carcinoma (CCOC) and endometrioid ovarian carcinoma (ENOC) are ovarian carcinoma histotypes, which are both thought to arise from ectopic endometrial (or endometrial-like) cells through an endometriosis interm…

UNLABELLED: Ovarian clear cell carcinoma (OCCC) is a deadly and treatment-resistant cancer, which arises within the unique microenvironment of endometriosis. In this study, we identified a subset of endometriosis-derived mesenchymal stem ce…

A missense single-nucleotide polymorphism (SNP) in the immune modulatory gene IL1A has been associated with ovarian cancer risk (rs17561). Although the exact mechanism through which this SNP alters risk of ovarian cancer is not clearly unde…

Estrogens and selective estrogen receptor (ER) modulators such as tamoxifen are known to increase uterine cell proliferation. Mounting evidence suggests that estrogen signaling is mediated not only by ERalpha and ERbeta nuclear receptors, b…

Loss of heterozygosity (LOH) at locus 10q23.3 and mutation of the PTEN tumor suppressor gene occur frequently in both endometrial carcinoma and ovarian endometrioid carcinoma. To investigate the potential role of the PTEN gene in the carcin…

Women who inherit mutations in the breast cancer susceptibility genes, BRCA1 and BRCA2, are predisposed to the development of breast and ovarian cancer. We used mice with a Brca1 mutation on a BALB/cJ inbred background (BALB/cB1+/- mice) or…

Endometriosis is a common gynecological disease in which tissue similar to the endometrium proliferates at sites outside the uterine cavity. Malignant transformation of endometriosis to endometrioid and clear cell ovarian carcinomas has bee…

Epithelial ovarian cancer comprises three major histological subtypes (serous, mucinous, and endometrioid), and it is becoming clear that the developmental pathways for these subtypes are fundamentally different. In particular, endometrioid…

Endometriosis is a very common gynecological condition in which tissue similar to endometrium proliferates at sites outside the uterine cavity, most commonly the ovary. Although it generally remains a benign condition, malignant transformat…

In order to study the effects of perinatal exposure to estrogens on the developing reproductive tract, outbred female mice were treated neonatally (days 1 to 5) with varying doses of diethylstilbestrol (DES) and sacrificed from 1 to 18 mont…

The arachidonic acid lipoxygenase products 15-hydroxyeicosatetraenoic acid, 12-hydroxyeicosatetraenoic acid, and 5-hydroxyeicosatetraenoic acid and the arachidonic acid cyclooxygenase product prostaglandin E2 were quantitated in 11 malignan…
