The development of poly(ADP-ribose) polymerase (PARP) inhibitors as a new class of anticancer agents has created a tremendous amount of hope in the ovarian cancer community, especially in the high-risk, difficult-to-screen, hereditary ovarian cancer population. More »
This article reviews the trials that have been conducted with PARP inhibitors in epithelial ovarian cancer, fallopian tube cancer, and primary peritoneal cancer, and places the impact of those results in the larger context of PARP inhibitor development. More »
A new study has made a step forward toward better characterization of sporadic ovarian tumors by identifying their DNA repair protein expression profile. More »
Despite the fact that it is highly curable if diagnosed early, ovarian cancer causes more mortality in American women each year than all other gynecologic malignancies combined. More »
Although it is well known that ovarian endometriosis occasionally gives rise to ovarian cancers with specific histology such as endometrioid and clear cell carcinomas, its etiology is not fully understood. We have shown that a stressful microenvironment within the endometriotic cyst may lead to cancer development by inducing unique gene expressions, which potentially serves as a molecular marker for treatment modality. In this review, by referring to other articles in this field, we explore how the carcinogenic microenvironment affects the phenotype and gene expression of a cancer, and how we can develop new treatment based on this concept.
Variably-spliced prolactin receptors (PRLRs) and PRL are expressed by the ovariancancer cell lines, TOV-112D, OV-90 and TOV-21G. Incubation in the PRLR antagonists, G129R- or S179D-PRL, or anti-PRL reduced cell number, indicating a functional autocrine PRL growth loop. Added PRL promoted, and the antagonists decreased, cell migration. When cells were stressed, added PRL decreased apoptosis and increased survival, and the antagonists had the opposite effect. Cells expressing higher long:short PRLR ratios had increased growth, survival and migration in response to PRL. Results suggest that PRLR antagonists may be therapeutically beneficial in ovariancancer.
