| Research Abstract |
The effects of 3 types radiation (X-ray, carbon ion beam and proton beam) on cancer metastasis were investigated in this study. As the results, the cell migration and invasion capability were increased by low dose X-ray or proton beam irradiation. On the other hand, carbon ion beam decreased these metastatic potentials. Furthermore, the cells that low dose X-ray or proton beam was irradiated enhanced the expression of FAK (Focal adhesion kinase) which had important role to form desmosome and X-ray enhanced the expression of Rho family proteins which related to regulating cytoskeleton. In case of carbon ion beam, the expressions of these proteins in the cancer cells were suppressed. This study suggested that carbon ion beam might suppressed cancer metastasis.
