| Outline of Final Research Achievements |
We successfully prepared and cultured cancer tissue-originated spheroids
(CTOS) from endometrial cancers. Then, we screened 79 molecular targeting drugs using two CTOSs. Among several hits, we focused on everolimus and YM155, a survivin inhibitor. When sensitivity to everolimus or YM155 was assessed in 12 CTOSs, the sensitivity varied substantially. The phosphorylation status of the mammalian target of rapamycin complex 1 downstream molecules before and after everolimus treatment did not predict the effect of the drug. In contrast, the CTOS sensitive to YM155 showed remarkable cell death. The effect of YM155 was also confirmed in vivo. The histological type correlated with YM155 sensitivity; non-endometrioid adenocarcinomas were sensitive and endometrioid adenocarcinomas were resistant. Thus, sensitivity assays using cancer tissue-originated spheroids from endometrial cancers may be useful for screening drugs and finding biomarkers.
