| Outline of Final Research Achievements |
A current working model for the metastatic process of ovarian carcinoma suggests that cancer cells are shed from the ovarian tumor into the peritoneal cavity and attach to the layer of mesothelial cells that line the inner surface of the peritoneum, and several studies suggest that hepatocyte growth factor (HGF) plays an important role in the dissemination of ovarian cancer. The in vivo and in vitro experimental models revealed that HGF secreted by ovarian cancer cells induces the MMT and stimulates the invasion of mesothelial cells. Furthermore, manipulating the HGF activity affected the degree of dissemination and ascites formation. Finaly, we demonstrated that HGF secreted by ovarian cancer cells plays an important role in cancer peritoneal implantation (Gynecologic Oncology 139: 345-354, 2015).
