I. Background | |||
MUC17 基因(染色體 7q22)編碼一種大型跨膜黏蛋白,屬于黏膜屏障核心組件。其 蛋白結構包含信號肽、中央重復區(含可變數目串聯(lián)重復序列,VNTR)、兩個(gè) EGF 樣結 構域、SEA 模塊、跨膜域及含潛在磷酸化位點(diǎn)的胞質(zhì)尾區。這種設計使其兼具物理屏障與 信號調控功能:O-糖基化形成的黏液層直接抵御病原體(如腸侵襲性大腸桿菌)入侵,同 時(shí)通過(guò) SEA 模塊參與蛋白酶解調控,維持腸道上皮動(dòng)態(tài)平衡。 臨床研究揭示其雙重角色:在炎癥性腸?。ㄈ缈肆_恩?。┲?,MUC17 表達異常導致屏 障功能受損,增加感染風(fēng)險;而在胰腺癌中,MUC17 作為促癌因子,通過(guò)膽汁酸誘導加速 腫瘤進(jìn)展,并與 MUC4 共表達,成為潛在預后標志物。 | |||
