| Research Abstract |
We noticed CD133 as a stem cell marker in ovarian cancer. The present study was designed to evaluate the tumor-formation ability of CD133+ cells in ovarian YST cell lines and to examine characteristics of CD133+ cells such as cell growth, and invasiveness. Our data suggest that ovarian YST may be maintained by a rare fraction of cancer stem-like cells that express the cell surface marker CD133. CXCR4 levels were markedly higher in NOY1-CD133+ cells than CD133- NOY1 cells . NOY1-CD133+ expressed slightly higher levels of CD44 expression when compared with their CD133- counterparts.We also examined GPC3 expression in surgically resected ovarian carcinoma tissues. We tried immunotherapy in ovarian cancer. We investigated the expression ofonco-fetal antigen, GPC3. Our results showed that GPC3 was expressed in tumor cells from 51.6% of ovarian clear cell carcinoma although other histotypes were not stained, GPC3expression was observed in intracellular lesions as well as in the cell membrane, Furthermore, we showed that HLA-classI was expressed in tumor cells from 90% of ovarian clear cell carcinoma. We showed the validity of GPC3 peputide immunotherapy. We started a phase II clinical trial of the GPC3 derived peptide vaccine for ovarian clear cell adenocarcinoma patients
