Abstract
目的:观察蛋白激酶Cα(protein kinase Cα,PKCα)、AnnexinA2和S100A10蛋白在胃癌组织中的表达及意义,为获取胃癌诊断相关的蛋白分子提供实验依据.方法:Westernblot分析PKCα、AnnexinA2和S100AIO蛋白在正常胃黏膜与胃癌组织中的表达情况;免疫组织化学染色观察组织芯片中三者的表达情况,并分析其临床病理学意义.结果:(1)Westernblot检测结果显示,PKCα、AnnexinA2和S100A10蛋白在胃癌组织中表达较正常胃黏膜组织中高(P〈0.01);(21免疫组织化学染色结果显示,PKC仪蛋白在正常胃黏膜及胃癌组织中的阳性表达率分别为8.82%(3/34)和76.54%(62/811:AnnexinA2蛋白在正常胃黏膜及胃癌组织中的阳性表达率分别为5.88%(2/34)和79.01%(64/811:S100A10蛋白在正常胃黏膜及胃癌组织中的阳性表达率分别为2.94%(1/34)、59.26%(48/81);(3)PKCα、AnnexinA2和S100A10蛋白在胃癌组织中的阳性表达率较正常胃黏膜组织高(P〈0.01).结论:PKCα、AnnexinA2 和S100A10蛋白在胃癌组织中表达较正常胃黏膜组织中表达高,其表达与胃癌的发生及分化程度有关.
