| Outline of Final Research Achievements |
We generated three PDX (patient-derived xenograft) models from patients with adenoid cystic carcinoma. One model has distant pulmonary metastasis which is of substantial importance on deciphering the mechanisms of invasion in adenoid cystic carcinoma. By comparing genome-wide data of patient’s peripheral blood, primary tumor, and PDXs (subcutaneous tumor and lung metastasis), we detected characteristic genomic alterations of metastatic tumor cells. To reveal factors promoting metastasis, we examined intravenous administration and invasive surgical procedure to the PDX model but failed to identify any possible factors that might affect metastatic potential. We have also developed the international research project collaborated with University of California, San Diego.
