Outline of Final Research Achievements

All malignancies can cause bone metastasis, and many cancer patients have bone metastasis. To obtain the molecular insights of bone metastasis and develop clinical applications, we performed multi-OMICS study. Using tumor tissues of primary and bone metastatic legion, we compared the protein and miRNA expression in a global way. We identified differently expressed genes. The functional significances of identified genes were examined by in vitro gene silencing study, and confirmed that the specific inhibitors affected the growth of tumor cells, The protein with overexpressed level in bone metastasis was released from the tumor cells, and we measured it by specific antibody.
