Outline of Final Research Achievements

Immunohistochemical analysis of clinical samples from breast cancer patients revealed that three kinds of TRIM family proteins, namely TRIM25, TRIM44, and TRIM47, are poor prognostic factors. It is suggested that enhanced NF-kappaB signaling is the underlying mechanism for TRIM44 and TRIM47. In addition, interaction of TRIM47 and certain proteins could cause the enhanced NF-kappaB signaling. Further, xenograft mice model suggested suppression of TRIM47 expression could have a therapeutic value. On the other hand, immunohistochemical analysis suggested that a TRIM25-interacting molecule in the context of innate immunity also has pathological role in the progression of breast cancer.

Academic Significance and Societal Importance of the Research Achievements

本研究においては、複数の乳癌の予後不良因子を蛋白質レベルで同定した点に学術的な意義を有する。遺伝子の増幅やメッセンジャーRNAレベルで示した報告に比べて、実際に機能している分子である蛋白質レベルにおける証明はより説得力を有している。さらに、TRIM47の機能解析において、新たな分子との相互作用を介したメカニズムを示した点においても学術的な新規性を有する。本研究で同定した予後不良因子や関連蛋白質の知見を活用することにより、有効なオーダーメード医療を行う道が開け、現在の日本の乳癌の罹患率の高さや死亡数の増加傾向を鑑みると、社会的な意義も有しているといえる。
