| Outline of Final Research Achievements |
Malignant pleural mesothelioma (MPM) is a well-known tumor which shows treatment resistance and dismal prognosis. There is a need to resolve the cause of this disease and to develop a new treatment. We investigated the cause of MPM and the new treatment strategy by focusing on the cancer stem cell and micro-RNA (moRNA) related to cancer stem cell markers. We performed a comprehensive miRNA expression analysis to find the families of miRNA-34 and miRNA-200 as candidate of cancer stem cell related miRNA of MPM. We analyzed the effect of transduction of these miRNAs on expression of cancer stem cell related makers, cell viability, and drug sensitivity. We are investigating the new candidates of miRNAs relaeted to cancer stem cell of MPM by cell sorting method.
