Outline of Final Research Achievements

The microtubule targeting agent Paclitaxel is prescribed widely for various malignancies, including breast adenocarcinomas. However, the precise mechanism of Paclitaxel-induced apoptosis is not clearly understood. From these findings, we used siRNA screening approach to identify genes involved in Paclitaxel-induced apoptosis. Here we identify that candidate gene, which is required for the activation of pro-apoptotic Bcl-2 family proteins, Cytochrome c release from the mitochondria and play an important role of Paclitaxel-induced apoptosis. Furthermore, using the residual of the tissue clinical specimen collected from the breast cancer patient, we analyzed the effects of candidate gene on microtubule dynamics and determine whether it becomes biomarker for the effect and susceptibility for Paclitaxel.

Academic Significance and Societal Importance of the Research Achievements

転移性乳癌において外科療法が困難な乳癌に対しては薬物療法が主流となっているが、内分泌療法が期待できないタイプの乳癌では化学療法に頼らざるを得ないのが現状である。そこで化学療法薬の細胞死誘導機構を詳細に解析することで、感受性と抵抗性との違いを決定づける分子機構の一端を解明し、サブタイプ別あるいは遺伝的解析を組み合わせることで、どの薬剤がより効果が得られるかを予測診断できないかと考えている。
したがって薬剤投与前からどの程度の効果が見込めるかを知ることにより、今後の治療方針に活用できることが期待され、また患者のQOLを高めること、無駄な投薬を避けることにつながることも期待される。
