背景
纤连蛋白(FN)是细胞外基质(ECM)的核心糖蛋白组分,也是主要的细胞黏附分子,在胚胎发育、早期囊胚形成(桑椹胚阶段 FN1 表达显著上调可佐证)、机体生长及伤口愈合过程中承担关键功能。 结构上,每个纤连蛋白单体由同源重复序列构成:包含 12 个 I 型重复区、2 个 II 型重复区以及 15–17 个 III 型重复区;其中 2 号片段包含前 7 个 III 型重复序列,并依靠关键的 III2 结构域,在纤丝生长过程中介导分子自组装。通过 ED-A、ED-B、III-CS 区段的 mRNA 可变剪接,再经翻译后修饰,纤连蛋白可生成多种功能亚型。 各类纤连蛋白亚型可作为多功能配体,结合纤维蛋白、肝素、硫酸软骨素、胶原 / 明胶及多种整合素受体,进而调控多条细胞信号通路。除支撑组织结构外,纤连蛋白还参与血小板血栓形成,同时介导血管重构、动脉粥样硬化、心肌梗死后心脏修复等血栓相关病变。 此外,细胞周边纤连蛋白发生降解、肿瘤周边基质纤连蛋白表达升高,可作为细胞恶性转化的早期标志物,凸显其临床研究价值,也使其成为探究肿瘤进展的潜在研究靶点。
