Outline of Final Research Achievements |
10 μM BBI-608 alone increased ROS in mesothelioma cells than irradiation with 5 Gy or 10 μM Alimta alone. When 10 μM BBI-608 was used in combination with 2 Gy irradiation, ROS production increased more than 2 Gy irradiation or BBI-608 alone. Irradiation (5Gy) increased ROS production more than irradiation (2Gy), but it was not as high as that of BBI-608 single agent (10 μM). When BBI-608 (10 μM) was used in combination with 5 Gy irradiation, the increase in ROS production was equivalent to combination with 2 Gy irradiation.It is considered that the synergistic effect of BBI-608 and radiotherapy is due to this ROS production.

Academic Significance and Societal Importance of the Research Achievements |
Stat 3阻害剤であるBBI-608は癌幹細胞に対する抑制効果が期待されている。本研究はBBI-608と放射線治療の併用時の抗腫瘍効果増大の確認と、そのメカニズムを明らかにすると同時に、動物モデルを用いて同時併用時の安全性が確認出来た。
