| Outline of Final Research Achievements |
[Objective] microRNAs have key roles in the onset, development and drug resistance of cancer. We identified miR-34b as a tumor suppressor-type microRNA with expression that is epigenetically suppressed in endometrial cancer. In this study, the antitumor effect of combined miR-34b and antitumor drugs on endometrial cancer was examined.
[Results] There was no change in cell viability after administration of miR-34b following application of cisplatin or adriamycin to HEC-108, HEC-1B and KLE cells. However, after treatment with paclitaxel, cell viability after administration of miR-34b decreased in all three cell lines. Tumor development occurred 14 days after transplantation of HEC-1B cells in nude mice. Drugs were administered on that day and thereafter. The tumor diameter significantly decreased in mice treated with paclitaxel + miR-34b compared with the results for other treatments (p<0.05).
