Outline of Final Research Achievements

Hepatocyte-specific knockout mice for CBP and P300 were generated by crossing Alb-Cre mice. After continuation of a choline-deficient high-fat diet, a reduction in the number of hepatocellular carcinomas was observed in CBP/Alb-Cre KO mice. This indicates that CBP/β-catenin signaling downstream of Wnt/β-catenin signaling is more involved in NASH-induced hepatocellular carcinoma development than P300/β-catenin signaling.

Academic Significance and Societal Importance of the Research Achievements

国内がん死因の第5位に位置している肝細胞がんは再発を繰り返すことが特徴で5年相対生存率が低い予後不良のがんである。近年、薬物療法としてチロシンキナーゼ阻害薬や免疫チェックポイント阻害薬が使用されているが奏効率は高くなくより奏効率の高い治療薬の開発が望まれている。本研究からはCBP/βcateninシグナルがNASH由来の肝発がんに関与していることが示唆され、治療薬のターゲットとなり得る。
