Outline of Final Research Achievements

Although molecular diagnosis of brain tumor is important, its timing influences the treatment plan and course. Intraoperative diagnosis will make us quickly choose and start appropriate after treatment. Therefore, we aimed to establish the technology.
i-densy makes Q pobe and objective DNA hydrogen bond each other. After this i-densy makes that complex denature by heating and emission. Utilizing the fact that the denaturing temperature differs according to the mutation, genetic diagnosis is performed. It takes only about 90 minutes. Development of the new probe will make us able to do genetic diagnosis among each tumor.
In our study, we established the probe against IDH1 R130, which is important for glioma, and H3F3A. In addition, we chose the candidate for the one against IDH2 R172.
