| Outline of Final Research Achievements |
To verify the prediction abitities of patient's outcomes in GCTBs, the protein expressions of the GPX family (especially GPX1 and GPX3) and the gene alteration of TP53 gene were analyzed using the large validation cohort. The results of validations showed that the expression of GPX family and gene mutation of TP53 had statistical significant difference of prognosis in GCTBs. In order to establish the protein profiles of GCTBs and elucidate the biological characteristics of GCTBs, comprehensive protein expression analyses were performed using frozen surgical specimen of GCTBs and the identified protein profiles were analyzed according to clinico-pathological features including patient's outcome and drug sensitivities. We found the characteristic proteins which were associated with denosumab treatments and sensitivities in GCTBs which is a therapeutic agent for GCTB.
