Outline of Research at the Start

臨床的にIMiDsは骨髄腫治療において血小板減少を高頻度に生じ、治療中断の重要な原因である。我々は、IMiDsによる血小板減少の原因解明に取り組み、Aromatase(AROM)がその原因となるneo-substrateであることを見出した。本研究は、AROM分解メカニズム解明を進めると同時に、IMiDsによるAROM分解が閉経後乳癌治療へ応用可能か検討し、新規乳癌治療法開発につなげることを目的とする。

Outline of Final Research Achievements

We have identified aromatase as a neo substrate of cereblon responsible for thrombocytopenia induced by IMiDs; IMiDs promote the recruitment of aromatase to cereblon, resulting in the degradation of aromatase in a proteasome-dependent manner, and the degradation of aromatase lead to the inhibition of proplatelet formation (PPF), an essential step for platelet production in human. Since aromatase represents a critical therapeutic target for postmenopausal breast cancer, we sought to establish a novel therapeutic strategy against breast cancer using IMiDs as a degrader of aromatase. Furthermore, we also tried to identify another neo substrate of cereblon to explain the pleiotropic effect of IMiDs, and identified “molecule X” as a neo substrate of cereblon responsible for IMiDs-induced thrombosis.

Academic Significance and Societal Importance of the Research Achievements

本研究の遂行によりIMiDsによる血小板減少症の原因としてアロマターゼの分解が生じること、さらにIMiDsによる血栓症リスク上昇の原因として、巨核球、血小板において分子Xの蓄積が生じることを明らかにした。これらの結果からIMiDsによるメジャーな副作用の分子学的メカニズムを明らかとすることができた。さらにIMiDsによるアロマターゼ分解を閉経後乳癌の治療への応用の可能性を評価する研究を行い、今後応用のための基盤的研究としての重要な意義があると考えられた。
