| Outline of Final Research Achievements |
In this research project, we aimed (1) construction of a new murine model of bone metastasis and (2) identification of critical molecular mechanisms underlying bone metastasis. In the aim 1 we invented intra-caudal artery injection to overcome several drawbacks of current bone metastasis models. This model could change the approach most investigators in bone metastasis research. In the aim 2 we tackled molecular mechanisms governing bone metastasis using noninvasive optical imaging and the murine bone metastasis model from the aim 1. Noninvasive imaging visualized activation of key transcriptional factors at specific processes in bone metastasis. This might be coupled with interactions between cancer cells and resident bone marrow cells. To provide further mechanistic understanding, we analyzed cellular interactions in the bone marrow with standard biochemical studies. These might pave the way for development of new therapeutic strategies.
