摘要: 目的 利用数据库分析肝细胞癌(HCC)组织核转运蛋白XPO5基因水平及其与患者预后的关系。方法 在Oncomine数据库,分析HCC组织XPO5基因水平,并在GEPIA数据库中选择TCGA数据进行验证。在MethHC数据库分析HCC组织XPO5基因甲基化水平。在GEPIA的TCGA数据库,分析XPO5基因水平对HCC患者生存期的影响以及不同病理学分级的HCC组织XPO5基因水平差异。在STRING数据库分析与XPO5相互作用的蛋白种类。结果 与正常肝组织比,HCC组织XPO5基因呈高水平(P<0.01),且在病理学分级为III级组织XPO5基因水平最高;HCC组织XPO5基因高水平患者总体生存期和无病生存期较低水平患者显著缩短,差异具有统计学意义(P<0.01);HCC组织XPO5基因较正常肝组织甲基化水平显著降低,差异具有统计学意义(P<0.005),甲基化降低区域主要位于基因体区域;蛋白相互作用网络分析显示,XPO5与DICER1和RAN等蛋白相互作用,并参与了miRNA的调控。结论 XPO5基因在HCC组织中呈高水平状态,这种高水平状态可能与癌组织不同病理学分级有关,并影响患者的生存期。采用数据库进一步挖掘分析研究结果可能为临床采用生物学方法HCC患者提供参考依据。

Abstract: Objective To analyze cancerous XPO5 gene level changes in patients with hepatocellular carcinoma (HCC) and its clinical significance based on internet data bank. Methods The XPO5 mRNA in cancerous tissues in patients with HCC was analyzed by using Oncomine database and verified in TCGA GEPIA database. The methylation level of XPO5 gene in HCC tissues was analyzed by using MethHC database. The impact of XPO5 gene on the survival of patients with HCC was analyzed by GEPIA. The STRING database was used to analyze certain proteins interacted with XPO5. Results XPO5 mRNA was upregulated in cancerous tissues in patients with HCC compared with in normal liver tissues (P<0.01),and its level increased mostly in cancerous tissues with pathological grading Ⅲ;the survival in HCC patients with high cancerous XPO5 mRNA level were significantly shorter than in patients with low XPO5 mRNA level(P<0.01);low methylation in XPO5 gene body was found in HCC tissues (P<0.005);the analysis of protein interaction network showed that XPO5 interacting with DICER1 and RAN proteins participated in miRNA regulation. Conclusion XPO5 gene is up-regulated in cancerous tissues in patients with HCC, which might be associated with prognosis of patients with HCC. At present,we can fully use internet database online to review the documented literature and provide reference for the biological treatment of patients with HCC.
