MCAM
CD146又称黑色素瘤细胞黏附分子(MCAM)或细胞表面糖蛋白MUC18,是一种单次跨膜糖蛋白,属于免疫球蛋白超家族(Igsf)成员,与许多细胞黏附分子(cell adhesion molecule,CAM)有同源性。CD146通常是作为层黏连单板α4的受体起作用,是血管壁中普遍存在的基质分子。这也意味着,CD146可在血管壁组分细胞中高表达,包括血管内皮细胞、平滑肌细胞和周细胞。CD146作为黏附分子中的一员,通过与其配体相互作用,介导细胞间及细胞与基质间的作用是黏附分子的基本功能特征。CD146活化后,可通过其胞质区与p59fyn形成复合物。活化的p59fyn可进一步引起酪氨酸激酶p125PAK磷酸化并与桩蛋白(paxillon)结合,这也表明CD146可通过其胞内结构域对细胞外到细胞内的信号进行传导和交流,有助于局部黏连聚集、细胞骨架重组、维持细胞结构和调节细胞的功能。
CD146除了具有黏附分子特性,最近的研究表明CD146在多种细胞生理过程中表现活跃,包括发育、信号转导、细胞迁移、间充质干细胞分化、血管生成和免疫应答。其中,目前研究最多的是参与肿瘤的血管形成和转移。肿瘤的生长和扩散转移与其微血管生成和数量增加密切相关,无论是原发肿瘤还是转移肿瘤在生长扩散过程中都依赖血管生成。正常状态下,血管生成会处于平衡状态。这种平衡在肿瘤微环境中会被打破。目前,CD146调节肿瘤血管形成的机制可能包括激活基质金属蛋白酶2(MMP-2),该酶可降解基底膜和细胞外基质,激活生长因子,主要是血管内皮细胞生长因子(VEGF),有利于肿瘤转移和肿瘤血管形成。
