| Outline of Final Research Achievements |
Some populations of meningiomas show malignant clinical behavior in despite of benign histological diagnosis.In this study, novel diagnostic criteria other than histological classification to determine malignant subgroup of meningiomas is presented. A subgroup of meningiomas is characterized by aberrant hypermethylation of the subset of genes in the early stage of tumorigenesis, and our findings highlight the possibility of speculating potential malignancy of meningiomas by assessing methylation status. On the other hand, molecular biological studies about function of hypermethylated genes didn’t show reproducible results. Fukushima medical university brain tumor tissue bank established for basic research has collected over 250 cases of intracranial tumors.
