| Research Abstract |
Most patients with ovarian cancer are diagnosed at an advanced stage. Although treatment for ovarian cancer consists of surgical treatment and combination chemotherapy, there is still poor prognosis associated with drug resistance. As an experimental model system for epithelial ovarian carcinogenesis, we established immortalized human ovarian surface epithelial (OSE) cell lines. Using this system, we clarified the production of hCG α subunit and β subunit in the OSE cells, and the effect of hCG β subunit in anchorage-independent growth of the OSE cells. Moreover, many ovarian cancer tissues also expressed hCG β subunit. This discovery will provide a development of new therapeutic strategies for ovarian cancer.
