| Outline of Final Research Achievements |
We transfected eGFP and luciferase genes into human cancer cell lines, including lung cancer cells, and established in vivo imaging model of brain metastasis (brain tumor) with these cells by intracranial inoculation. These cancer cells produced various angiogenesis-related molecules, but there was no correlation between tumorigenecity in the brain and angiogenesis-related molecules. In the in vivo imaging model, anti-VEGF antibody did not inhibit tumor progression of VEGF-high producing cancer cells. These results suggest that brain metastasis may be regulated multiple factors in addition to VEGF-induced angiogenesis.
