Par3、Par6及aPKC蛋白在胃癌发生、发展中的意义

摘要

目的：探讨Par3、Par6和aPKC在胃癌中的表达及意义。方法采用免疫组化法分别检测Par3、Par6和aPKC三种蛋白在153例胃癌各个位点(即胃癌黏膜层、肿瘤中心、侵袭前沿)及淋巴结转移灶中的表达,并以正常胃黏膜作为对照。结果Par3、Par6和aPKC在胃癌组织各个位点的表达水平均显著低于正常胃黏膜(P0．05)。结论Par3、Par6和aPKC表达下调促进胃癌的发生、发展。%Purpose To investigate the expression of Par3, Par6 and aPKC in gastric carcinoma and their significance. Method Ex-pression of Par3, Par6 and aPKC, by using immunohistochemistry, was detected in different sites of gastric carcinoma ( including the gastric carcinoma in gastric mucosa, the central area and the invasive front of gastric carcinoma) and the lymph node metastasis, using normal gastric mucosa as controls. Results Expression of Par3, Par6 and aPKC in different sites of gastric carcinoma was lower than in that of normal gastric mucosa (P0. 05 ) . Conclusions The down-regulation expression of Par3, Par6 and aPKC may promote the carcinogenesis and progression of gastric carcinoma.
