NRG1:极具潜力疾病治疗靶点,NRG1融合更为罕见致癌基因
NRG1(神经调节蛋白1,又称为ARIA、HRG、GGF、NDF),是表皮生长因子(epidermal growth factor, EGF)家族成员之一。NRG1主要表达于胶质细胞和神经元以及乳腺等器官,在神经系统、心肌、乳腺发育中起重要作用。NRG1介导的信号主要经由ERBB2、ERBB3和ERBB4受体,与ERBBs结合后,形成二聚体复合物NRG1/ERBBs,激活ERK、AKT、MAPK和JAK-STAT等信号通路。此外,NRG1能与很多其他不同的基因位点融合,比如CD74,SLC3A2,SDC4等,形成新的融合基因后在细胞膜上表达对应的融合蛋白,NRG1基因融合可激活并保留NRG1蛋白的EFG样结构域,使NRG1融合可持续与ERBB受体成员结合。由此,NRG1融合会导致相关信号通路持续活化,引起细胞增殖失控,导致肿瘤发生。NRG1作为一个新星靶点,其在肿瘤中的作用机制有待进一步探索。但NRG1融合的发现,作为一个罕见的致癌驱动基因,其双特异性抗体Zenocutuzumab(MCLA-128)在胰腺癌患者中表现出了良好的疗效,有望为肿瘤患者带来新的希望。
Recombinant Human NRG1 活性蛋白实验验证数据
(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
