Outline of Final Research Achievements

BH3 profiling identified BCLXL protein as a functional role for 5-FU resistance in colon cancer cell lines. Knockdown of BCLXL protein recovered the sensitivity to 5-FU in 5-FU resistant colon cancer cells. Furthermore, mice study showed that BCLXL inhibitor could both control tumor growth and cause apoptosis in 5-FU resistant colon cancer cells. In summary, BCLXL inhibitor is thought to be one of the promising drug for 5-FU resistant colon cancer.

Academic Significance and Societal Importance of the Research Achievements

BH3プロファイリングという新しい解析手法により、今までの方法では分からなかった抗がん剤の耐性メカニズムを明らかにした。このメカニズムを標的とした薬剤を使えば、大腸がんを効果的に殺すことが可能となり、さらに以前から使っていた抗がん剤も再び効くようになることが分かった。
