研究领域

一、焦磷酸肌醇(IP7)代谢小分子在功能机制研究 。

       G蛋白偶联受体(GPCR)信号转导通路的新型第二信使三磷酸肌醇(IP3)能被一系列的肌醇激酶进一步磷酸化生成多种多磷酸肌醇(IP4-8),其功能了解不多。其中,能量高,不稳定的焦磷酸肌醇(IP7/8)的作用原理尤为难解。我们之前发现IP7是肿瘤细胞里调控凋亡和转移的命运抉择开关,在早期通过促凋亡来抑制肿瘤发生,后期则通过诱导上皮细胞-间充质转换来促进肿瘤恶化与转移(Rao et al. Mol Cell, 2014;Rao et al. PNAS, 2015)。但是,IP7在疾病微环境中所感应的上游信号不清楚。通过研究焦磷酸肌醇特异的合成和水解酶的催化及调控机制,我们着眼于在细胞和小鼠模型里发掘焦磷酸肌醇介导的生理过程(如代谢稳态和肿瘤转移),并揭示相关的信号转导通路。在此基础上,我们通过化学生物学和生物化学的方法寻找小分子的直接作用位点和作用模式,希望能够归纳出焦磷酸肌醇作用的普遍规律。基于焦磷酸肌醇在癌症等疾病发生过程中的作用,我们的机制和功能研究或可为治疗相关疾病提供新靶点

二、CRL泛素连接酶的拟素化修饰的代谢调控与疾病。

       Cullin-RING ligase(CRL)家族泛素连接酶介导了总泛素化的20%,在癌症和糖尿病等多种疾病中失调,是新兴治疗靶点。CRL 还是最近兴起的蛋白降解靶向联合体(PROTAC)小分子药物所倚仗的泛素连接酶。CRL被拟素化修饰激活,受去拟泛素化酶CSN 抑制。我们研究CRL拟素化的代谢分子调控路径,包括多磷酸肌醇小分子和营养 (Rao et al. PNAS, 2014; Scherer,…, Rao*. PNAS, 2016; Lin,…, Rao*. PNAS, 2020)。相关发现或可为研发靶向CRL的新路径和解决PROTAC耐药提供理论基础。
