| Outline of Final Research Achievements |
We identified tubulin, coatomer protein complex subunit alpha, and basonuclin-1 as docetaxel-binding protein overexpressed in docetaxel-resistant subcell line established from prostate cancer cell line DU145 by utilizing magnetic beads. The relative RNA expression level (docetaxel resistant/sensitive) of those molecules was about 70%, 100%, and 20%, respectively. As tubulin, which is a target molecule for docetaxel was identified, the applied method should be appropriate as purifying docetaxel-binding protein. However, the expression profile of RNA and that of protein did not coincide, which made it difficult to judge the role of the identified docetaxel-binding protein in the development of docetaxel-resistance.
