花生凝集素可与肿瘤细胞分泌的粘蛋白结合,但不能与正常人结肠上皮细胞分泌的粘蛋白结合。花生凝集素被发现与实验诱导的CF-1小鼠远端结肠癌分泌的粘蛋白结合,但在对照动物的远端结肠癌中不结合。暴露于致癌物后对结肠组织进行的一系列检查显示,在组织学上正常但潜在的癌前病变上皮中存在与癌症相关的粘蛋白。因此,在化学致癌物-啮齿动物模型中,在随后发展为癌症的小鼠结肠部分发现糖蛋白结构的弥漫性变化,这是肿瘤组织出现的先兆。粘蛋白结构的变化可能被证明在某些结肠癌高危人群中识别癌前胃肠上皮有用。
The lectin peanut agglutinin binds to mucin secreted by neoplastic but not normal human colonic epithelial cells. Peanut agglutinin was found to bind to mucin secreted by experimentally induced neoplasms in the distal colons of CF-1 mice, but not in the distal colons of control animals. Serial examination of colonic tissues after exposure to carcinogen has revealed the “cancer-associated” mucin in histologically normal but potentially premalignant epithelium. Thus, in the chemical carcinogen-rodent model, a diffuse alteration in glycoprotein structure is found in that part of the murine colon that subsequently develops cancer, and this precedes the appearance of neoplastic tissue. Changes in mucin structure may prove to be useful in the identification of premalignant gastrointestinal epithelium in certain humans at high risk for colon cancer.
