背景(Background)
Tspan8是tetraspanin家族33个哺乳动物成员中的1个,由跨膜蛋白组成,这些蛋白横向组织,与整合素等其他膜伴侣一起或与整合素一起形成“tetraspanin-web”。这些平台在细胞内发出信号以调节许多细胞过程:粘附、迁移、侵袭或存活Tspan8与许多类型的癌症有关。据报道,在胶质瘤和结直肠癌、食管癌、肝癌、胃癌和胰腺癌中存在过表达。Tspan8通过与膜伴侣如α6β4整合素蛋白激酶C(PKC)激活、E-钙粘蛋白、EpCAM、claudin-7和CD44的结合来控制细胞和细胞-基质相互作用,从而发挥促侵袭功能。此外,Tspan8可能是一个有前景的新治疗靶点,因为Tspan8特异性抗体已被证明可以降低细胞运动,阻断体内肿瘤血管生成。
