摘要 为探讨p38-MAPK,u-PA和u-PAR蛋白在大肠癌的表达意义,采用免疫组织化学法观察大肠癌组织、癌旁组织和正常组织中p38-MAPK,u-PA和u-PAR蛋白表达情况。结果,p38-MAPK、u-PA和u-PAR蛋白在大肠癌组织的阳性表达率分别达82%(41/50),68%(34/50),72%(36/50)。在50例相应的癌旁黏膜组织中的阳性率分别为38%(19/50),30%(15/50),28%(14/50)。在正常黏膜中的阳性表达率分别为16%(8/50),6%(3/50),8%(4/50)。在大肠癌组织的表达高于癌旁黏膜,癌旁黏膜高于正常黏膜。在伴有淋巴结转移的大肠癌中阳性率明显高于不伴有淋巴结转移中的表达率。三者在大肠癌中的表达之间没有差异。结果显示,p38-MAPK可能是u-PA和u—PAR的激活物之一,三者在大肠癌的侵袭和转移中起重要作用。
