Outline of Final Research Achievements

In the current study, we performed whole exome and transcriptome sequences of chondrosarcoma, myxofibrosarcoma and giant cell tumor of bone. Myxofibrosarcoma was divided into 3 groups depending on the epigenome characteristics. Invasiveness and potential of pulmonary metastasis were regulated by microRNA133a in osteosarcoma and by microRNA135b in myxoid liposarcoma. Immunohistochemistries for TFE3, FGF23 and H3K27me3, and FISH for WT1 and USP6 were useful for pathological diagnosis of bone and soft tissue sarcomas.
