dc.description.abstract | Most ovarian cancers originate in the ovarian surface epithelium (OSE). Ovarian cancers might undergo epithelial-mesenchymal transition (EMT) in response to various mediators or regulators such as EMT-inducing factors. In this study, ovarian tumor specimens from patients were analyzed to demonstrate alteration of EMT-related markers according to benign and malignant types of ovarian cancers. In the three ovarian cancer cell lines, OVCAR-3, SKOV-3, and BG-1, the expression of epithelial (E-cadherin) and mesenchymal (vimentin) cell markers was identified by RNA and protein analysis. OVCAR-3 and BG-1 cells strongly expressed E-cadherin as well as morphological features such as epithelial cells, but vimentin was not observed. In contrast to these cancer cells, SKOV-3 showed a typical phenotype of mesenchymal cells. Alteration of EMT markers and EMT-related transcriptional factors were confirmed in clinical ovarian tissue samples obtained from 74 patients. E-cadherin was expressed in 57.1% of benign tumors, while vimentin was expressed in 83.3% of normal ovaries by western blot analysis in the tissue specimens. Evaluation of the EMT-associated transcriptional factors Snail, Slug, and Twist revealed that Snail was overexpressed by 7.1-fold in malignant ovarian cancer compared to normal ovaries or benign tumors. Although expression levels of other factors were higher in benign and malignant ovarian tumors, they were not closely correlated with the aforementioned ovarian cancer types. Overall, Snail may affect the EMT process in ovarian cancer development and upregulation of Snail expression followed by the downregulation of E-cadherin enhances the invasiveness of ovarian cancer. | - |
