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.

Academic Significance and Societal Importance of the Research Achievements

転移・再発乳癌は、ホルモン療法・抗がん剤治療・放射線治療などの集学的治療を用いても依然予後不良な病態である。特に原因として、抗癌剤耐性獲得による奏効率の低下があげられる。本研究では抗癌剤(タキサン系)耐性獲得の機序に関連するタンパクを同定し、耐性獲得マーカーとして臨床応用することを目的とした。
本研究期間内で臨床応用の可能性を検討できるには至らなかったが、本研究ではタキサン耐性獲得マーカーとして臨床応用が期待されるタンパク質およびmicroRNAの一部同定に成功しており、今後の臨床応用に向けた基礎的な解析を進めることができた。
