摘要: 旨在探讨gga-miR-155对马立克病病毒转化的肿瘤细胞系MDCC-MSB1细胞转录组水平变化的影响。本研究以MDCC-MSB1细胞为研究对象,首先将gga-miR-155模拟物及其阴性对照转染MDCC-MSB1细胞,在转染后48 h提取总RNA,用安捷伦2100核酸检测仪分析各组细胞总RNA的完整性,采用RT-qPCR分析gga-miR-155在MDCC-MSB1细胞中的过表达情况;然后利用高通量测序技术,分析gga-miR-155过表达后MDCC-MSB1细胞转录水平的变化,筛选差异表达基因,结合生物信息学分析预测差异表达基因中gga-miR-155靶mRNA。结果显示:制备了gga-miR-155在MDCC-MSB1细胞过表达样本并构建了高通量测序文库;与对照组相比,gga-miR-155过表达组的差异表达基因有87个,其中,上调表达的基因有47个,下调表达的基因有40个;GO与KEGG分析显示,这些差异表达基因显著富集于代谢和蛋白结合过程/信号通路;通过Targetscan和miRada软件预测下调表达基因中鸡BACH1为gga-miR-155的靶mRNA (P<0.05)。综上,过表达gga-miR-155可调控MDCC-MSB1细胞的转录组水平,差异表达基因中BACH1基因可能在gga-miR-155的作用下参与了MDCC-MSB1细胞的代谢过程。

Abstract: This study aimed to investigate the effects of gga-miR-155 on the transcriptomic level of Marek's disease virus transformed tumor cell line MDCC-MSB1 cells. In this study, MDCC-MSB1 cells were transfected with gga-miR-155 mimics and gga-miR-155 mimics NC, the total RNA of MDCC-MSB1 cells transfected with gga-miR-155 mimics and its negative control was extracted at 48 h after transfection and the integrity of total RNA was analyzed by Agilent 2100 nucleic acid detector respectively. After analyzing the overexpression of gga-miR-155 in MDCC-MSB1 cells by RT-qPCR, the changes in transcription level of MDCC-MSB1 cells after overexpression of gga-miR-155 were analyzed using the high-throughput sequencing technology. On this basis, the differentially expressed genes were screened, and the involved target mRNAs of gga-miR-155 in the differentially expressed genes were predicted combined with bioinformatics analysis. The RNA samples of gga-miR-155 overexpression in MDCC-MSB1 cells were prepared and a high-throughput sequencing library was constructed. Compared with the negative control group, 87 differentially expressed genes were found in the gga-miR-155 overexpression group, including 47 up-regulated genes and 40 down-regulated genes. GO and KEGG analysis showed that these differentially expressed genes were significantly enriched in metabolic and protein binding processes/signaling pathways. Chicken BACH1 was predicted as the target mRNA of gga-miR-155 by Targetscan and miRada software (P<0.05). The transcriptional level of MDCC-MSB1 cells was regulated by overexpressed gga-miR-155, and BACH1 gene in the differentially expressed genes may be involved in the metabolic process of MDCC-MSB1 cells under the regulation of gga-miR-155.
