摘要 结直肠癌是常见的消化道恶性肿瘤之一,其浸润转移是患者死亡的主要原因.同源异型框转录因子(CDX2)作为一种新发现的特异性的核转录因子,在正常消化道结肠和小肠上皮的发育中起着关键作用,CDX2基因的表达可显著诱导未分化细胞向肠上皮分化,对肠黏膜的分化与表型的维持、肠上皮细胞的增殖和分化发挥重要作用,对正常和肿瘤型肠上皮均有相对特异性和敏感性[1].绒毛蛋白(villin)是Ca^2+调节性肌动蛋白的结合蛋白,对正常小肠、结肠、胰腺导管和近端肾曲小管微绒毛刷状缘的形成起重要作用,在消化道腺癌组织中有特异性表达[2].本实验运用免疫组化方法检测两种蛋白在正常肠黏膜、腺瘤和腺癌中的表达,探讨其与临床病理参数之间的关系.
