| Outline of Final Research Achievements |
Cancer cells continue to acquire proliferative capacity, invasiveness, and metastatic potential by repeating gene mutations. For this reason, metastatic cancer tissues might have characteristics different from their original primary regions, which could affect strategies for radiotherapy. To investigate properties of metastatic cancers and their radiosensitivities, we established MDA-MB231-derived breast cancer cell lines, which were prone to cause metastasis. when transplanted into mouse.
We have successfully established three organ-oriented metastatic cell lines from a breast cancer cell line MDA-MB231. All of them posessed higher abilities in migration, invasion, and radiation resistancy than the parental cell line. Thus, these cell lines would be useful for examining mechanisms of organ-oriented metastasis and the radiosensitivity in breast cancer.
