| 摘 要： | 目的检测早期胃癌组织中微小RNA（miRNA）表达谱，筛选出早期胃癌的特征性miRNA。方法应用中通量基因芯片技术来检测5例早期胃癌组织及其癌旁组织标本中miRNA的表达。结果相对于癌旁组织，早期胃癌组织中共有36个miRNA表达下调，如miR-9．1、miR-103、miR-141等；12个miRNA表达上调，如miR．196a、miR．142．3p、miR-25等。结论在早期胃癌组织中表达异常的miRNA可能与胃癌发生发展有着一定的相关性。

| Abstract: | Objective To examine the micro-RNA （miRNA） expression profile in tissues of early gastric cancer and to screen the specific miRNA associated with gastric cancer. Methods Gene chip technology was used to detect the expression of miRNA in early gastric cancer tissues and adjacent normal tissues. Results Compared to adjacent normal tissues, a total of 36 miRNAs were down- regulated, such as miR-9-1, miR-103 and miR-141, while 12 miRNAs were up-regulated, such as miR-196a, miR-142-3p and miR-25, etc. Conclusion Abnormal miRNA expression level in early gastric cancer tissues may be associated to the development of gastric cancer. |
