肺癌可用靶点——CDH17

一、靶点介绍

6 s8 `& B$ S- c( O" s& D- Y人类肝肠黏着蛋白（human liver-intestine cadherin protein，CDH17）也被称为肠肽相关转运子 HPT-1，肝肠钙粘蛋白（liver-intestine cadherin，Licadherin），最初是在小鼠肝脏发现的一类钙依赖性粘附分子。[1]

二、可用药物

! h/ l& n  }# y" j1 o8 z! B, yBI 905711是一种同时靶向TRAILR2和CDH17的新型四价双特异性抗体，是一种专为克服先前策略缺点而设计的新型保肝TRAILR2激动剂。BI 905711能在体外有效地触发CDH17阳性的CRC肿瘤细胞的凋亡。

$ `0 F2 X5 b: I3 c7 W: vBI 905711在CDH17阳性的CRC移植瘤中证明了单药肿瘤消退，与伊立替康联合使用后效果进一步增强。BI 905711以顺式（同一细胞）和反式（相邻细胞）两种方式诱导细胞凋亡，即使在CDH17表达异质的异种移植模型中也转化为显著的抗肿瘤活性。[2]
