瞄准:为了识别,差别表示了 miRNAs,他们在肝炎 B 病毒(HBV ) 的目标联系了 hepatocellular 癌(HCC ) 。方法:六百和 67 人的 miRNAs 是 Taqman 低密度的 miRNA 数组(TLDA ) 在 HBV-HCC 纸巾分析的份量上。基因本体论(去) 并且小径分析的基因和染色体(KEGG ) 的京都百科全书被用来分析重要功能,差别的小径在 HBV-HCC 表示了 miRNAs。TargetScan 软件被用来预言 deregulated miRNAs 的目标。西方的弄污和酶试金被执行验证这些 miRNAs 的目标。结果:十起来调整的 miRNAs ( miR-217 , miR-518b , miR-517c , miR-520g , miR-519a , miR-522 , miR-518e , miR-525-3p , miR-512-3p ,和 miR-518a-3p )和 11 下面调整的 miRNAs ( miR-138 , miR-214 ,miR-214#, miR-199a-5p , miR-433 , miR-511 , miR-592 , miR-483-3p , miR-483-5p , miR-708 和 miR-1275 )被 Taqman miRNAs 数组识别并且在 HCC 和邻近的非肿瘤纸巾由反向的抄写聚合酶链反应证实了份量上。去并且 KEGG 小径分析表明在癌症的肌动朊细胞骨架和小径的那条规定是最可能的在 HCC tumorigenesis 起关键作用。(RPS6KA3 ) MiR-519a 和 ribosomal 蛋白质 S6 kinase 多肽 3 被 miRNA-mRNA 网络作为最重要的候选人预言。另外, cyclin D3 (CCND3 ) 和 clathrin 重链(CHC ) ,在 HCC 纸巾通常起来调整,分别地作为 miR-138 和 miR-199a-5p 的直接目标被验证。结论:我们的数据在 HCC tumorigenesis 建议 miR-138 和 miR-199a-5p 以及他们的目标 CCND3 和 CHC 的重要性,并且可以为综合生物信息学分析的可靠性提供更多的证据。
AIM: TO identify the differentially expressed miRNAs and their targets in hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC). METHODS: Six hundred and sixty seven human miRNAs were quantitatively analyzed by Taqman lowdensity miRNA array (TLDA) in HBV-HCC tissues. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were used to analyze the significant function and pathway of the differentially expressed miRNAs in HBV-HCC. TargetScan software was used to predict the targets of deregulated miRNAs. Western blotting and luciferase assay were performed to verify the targets of these miRNAs.RESULTS: Ten up-regulated miRNAs (miR-217, miR- 518b, miR-517c, miR-520g, miR-519a, miR-522, miR- 518e, miR-525-3p, miR-512-3p, and miR-518a-3p) and 11 down-regulated miRNAs (miR-138, miR-214, miR-214#, miR-199a-5p, miR-433, miR-511, miR-592, miR-483-3p, miR-483-5p, miR-708 and miR-1275) were identified by Taqman miRNAs array and confirmed quantitatively by reverse transcription polymerase chain reaction in HCC and adjacent non-tumor tissues. GO and KEGG pathway analysis revealed that "regulation of actin cytoskeleton" and "pathway in cancer" are most likely to play critical roles in HCC tumorigenesis. MiR- 519a and ribosomal protein S6 kinase polypeptide 3 (RPS6KA3) were predicted as the most significant can-didates by miRNA-mRNA network. In addition, cyclin D3 (CCND3) and clathrin heavy chain (CHC), usually up-regulated in HCC tissues, were validated as the di- rect target of miR-138 and miR-199a-5p, respectively.
