| Outline of Final Research Achievements |
We developed a luciferase-based luminescent assay system to evaluate cell migration using transformed NIH3T3 cells, and the assay system allowed to screen chemicals to inhibit cell migration. Subsequently, the mevalonate pathway appeared critical for migration in cancerous cells, including melanoma. Furthermore, we examined an amplified gene expression pattern using human melanoma cell lines that xenogeneically metastasized to the brain of NOD/SCID mice. Data suggested that 99 candidate genes were highly expressed in progressed melanoma. Further in silico analysis also suggested that some of candidate genes are associated in the biology of melanoma. Perhaps, the function of these candidate genes may be implicated in melanoma-specific tumor progression and its therapeutic resistance.
