摘  要:
为研究miR-M12-5p在马立克氏病病毒(Marek’s disease virus,MDV)感染过程中的调控作用,利用生物信息学方法对其候选靶基因进行预测分析,发现4个miR-M12-5p的结合靶点。体外双荧光素酶报告试验结果表明,miR-M12-5p可结合宿主鸡的氢离子电压门控通道1(HVCN1)基因mRNA的3'-UTR相应位点并发生特异性相互作用。实时荧光定量PCR分析进一步证实,miR-M12-5p能够在体内下调HVCN1基因的表达水平。上述结果表明,miR-M12-5p可以靶向调控宿主基因HVCN1的表达。

摘  要:
In order to study the regulatory role of miR-M12-5p,we predicted the host target genes utilizing bioinformatics method and obtained four candidate mRNA targets for miR-M12-5p. Dual luciferase reporter assay( DLRA) showed that miR-M12-5p could in vitro interact with the 3'-UTR of the mRNA of hydrogen voltage gated channel 1( HVCN1) gene. Further analysis results of the quantitative real-time PCR( qRTPCR) showed that the expression level of HVCN1 gene was in vivo down-regulated by miR-M12-5p. These data suggested that miR-M12-5p could regulate the expression of host chicken gene HVCN1.
