Cancer Lett:中科院大连化物所等揭示肝癌重要抑癌基因

2018-08-15 刘万生 宁振 王婷 中国科学报

中科院大连化物所生物技术研究部朴海龙团队与大连医科大学附属第一医院肝胆外科谭广团队合作,解释了肝癌细胞中去泛素化酶USP10的生物分子功能及分子机制。相关成果日前发表于《癌症快讯》杂志。

中科院大连化物所生物技术研究部朴海龙团队与大连医科大学附属第一医院肝胆外科谭广团队合作,解释了肝癌细胞中去泛素化酶USP10的生物分子功能及分子机制。相关成果日前发表于《癌症快讯》杂志。

肝癌是异质性强、死亡率高的难治性恶性肿瘤,我国肝癌患者的五年生存率仅为15%左右。这在很大程度上源自肝癌切除术后的高复发率、高转移率以及缺乏有效的治疗药物。

雷帕霉素靶蛋白(mTOR)是一个细胞生长、代谢的中央控制器,也是公认的抗癌药物的主要靶点。mTOR信号通路高度激活是肝癌发生的关键驱动因素之一。然而,mTOR上游基因PIK3CA和PTEN在肝癌中的突变率低,因此mTOR过度激活的机制仍不清楚。

研究团队发现,mTOR在肝癌中的异常激活与去泛素化酶USP10在肝癌中的低表达密切相关,并且USP10的表达与肝癌预后呈显著负相关。研究还发现,USP10通过去泛素化mTOR上游的两个关键调控蛋白分子,参与mTOR的激活抑制。

相关专家表示,该研究表明,USP10是肝癌的一个重要抑癌基因,并可作为以mTOR为治疗靶点的生物标记物。
