简介:目的:在既往的胃癌蛋白质组研究中我们已发现hnRNPA2/B1具有较高表达,本试验进一步探讨hnRNPA2/B1在胃癌中的表达情况及其与胃癌临床病理特征的关系。方法:用免疫组织化学方法检测122例胃癌患者的胃癌组织及癌旁正常胃粘膜中hnRNPA2/B1蛋白的表达。结果:hnRNPA2/B1在胃癌组织中核表达的阳性率为92.6%(113/122),其中伴有胞浆表达的阳性率为7.3%(9/122)。在癌旁非瘤组织中核表达阳性率为87.7%(107/122),未见胞浆表达。hnRNPA2/B1的表达状态与胃癌临床病理特征无关联。结论:在胃癌及癌旁非瘤组织中均可发现hnRNPA2/B1核表达,hnRNPA2/B1不能作为肿瘤相关的分子标志物。
