Outline of Final Research Achievements |
The prognosis of anaplastic thyroid carcinoma(ATC) is poor, and there is currently no established treatment to improve its outcome. We previously reported that EZH2 was highly expressed in ATC, and may be a therapeutic target; however, the effects of EZH2 on ATC growth currently remain unknown. We investigated the effects of an EZH2 inhibitor on four ATC cell lines. The cell-reducing effects of EZH2 inhibitor were detected in all ATC cell lines. The cell lines, which showed weak cell-reducing effects, had TP53 mutations. EZH2 inhibitor exerted suppressive effects on the growth of ATC cell lines and has potential as a therapeutic strategy; however, its effects may be attenuated in ATC with TP53 mutations.

Academic Significance and Societal Importance of the Research Achievements |
有効な治療法が少なく予後不良な甲状腺未分化癌において新しい治療戦略が求められている。われわれは他の甲状腺癌と比較して未分化癌ではEZH2が高発現となっていることを報告しており、本研究で甲状腺未分化癌細胞株を使用してEZH2阻害薬の細胞抑制効果を確認できたことは、EZH2阻害薬が甲状腺未分化癌の新しい治療戦略になり得る事を示している。
