  1. 治療抵抗性絨毛癌に対する全ゲノム解析に基づいた複合的がん免疫治療の確立

    Grant amount:\4290000 ( Direct Cost: \3300000 、 Indirect Cost:\990000 )

    絨毛癌は妊娠後に発生する腫瘍であり、半分が非自己であるため、一般的ながんのゲノムプロファイルとは異なり不明な点が多い。さらに希少がんであることが研究の妨げとなっており、治療抵抗性絨毛癌に対する新規治療法の開発が進んでいない。
    これらを踏まえ本研究では、絨毛癌における全ゲノム解析を行い、関連する治療抵抗因子や免疫応答因子などのバイオマーカーを同定し、新規治療法を探索することを目的とした。

    We investigated C2GnT expression in gestational trophoblastic diseases. We established C2GnT knockout (KO) cells with Jar and BeWo cells and investigated cytotoxicity of NK cells against those cells. MICA and MUC1 glycosylation were analyzed by immunoprecipitation. We incubated C2GnT-KO and control with TRAIL and cell viability were analyzed. We inoculated the C2GnT-KO and control cells subcutaneously into nude mice. C2GnT was highly expressed in trophoblasts of choriocarcinoma but not in hydatidiform mole and normal placenta. C2GnT-KO cells were more efficiently killed by NK cells than controls. Sugar chains attached by C2GnT on MICA and MUC1 in C2GnT-KO cells were significantly decreased. The cell viability of C2GnT-KO cells were lower than controls depending on TRAIL amount. C2GnT-KO promoted longer survival as compared with the controls. Choriocarcinoma cells may acquire a high malignant potential by expressing C2GnT with glycosylation to MICA and MUC1.

    For the purpose of not only the development of obstetrics and gynecology in Vietnam, but also creation of evidence worldwide and building of medical research resources to Japan, we investigated obstetric management and gynecological rare tumor in Vietnam at several facilities in Vietnam. In the present study, several findings, which are related to improvement of mothers and children's prognosis,were gained. First, Pregnancy with dengue fever causes thrombocytopenia, which is at risk of postpartum hemorrhage. Second, cesarean section scar pregnancy with an increase in cesarean section rate in Vietnam, could be managed by medication for only selected patients. Third, evaluation of cardiac function by ultrasound examination for fetal growth restriction would be beneficial. Lastly, we found that there was a high secondary rate after molar pregnancy in Vietnam and preventive measures might improve it.
