Outline of Final Research Achievements |
Paclitaxel-resistant subclone was made from breast cancer cell line MCF-7. Two proteins (PPIA, STMN1) were found out as candidates of drug resistance marker by proteome assay. The knock-down of these proteins significantly improved the drug resistance of paclitaxel. Furthermore, we focused on ABCB1, known as a protein of the drug resistance, and microRNAs bind to it. Our results suggest that these proteins and microRNAs can be markers of drug resistance.
