摘要(Abstract)：

猪轮状病毒（Porcine rotavirus,PoRV）是在世界范围内与严重腹泻疾病相关的主要肠道病原体，是新生仔猪肠炎和腹泻致死的重要原因之一。为了深入了解猪轮状病毒感染肠道后其致病机制以及引起宿主的抗病毒和修复机制，我们分别饲喂培养基和猪轮状病毒病毒液5d后，采取5 d、10 d、15 d、20 d、25 d小鼠空肠组织进行高通量转录组测序分析。利用基因本体论（Gene Ontology,GO）数据库功能富集分析、京都基因与基因组百科全书（Kyoto Encyclopedia of Genes and Genomes,KEGG）通路富集分析差异表达基因（Differentially Expressed Gene,DEGs），选取部分差异表达基因，进行qRT-PCR验证。结果显示，与对照组相比，5个时间段上调DEGs有849个，下调DEGs有824个。对DEGs进行5个功能富集，有共同差异基因15个。这些差异表达基因广泛参与脂质合成与代谢、免疫、细胞增殖、细胞凋亡等活动，主要注释到PPAR、NOD-like、IL-17等信号通路中。qRT-PCR验证上皮细胞增殖相关基因PBLD、CCL24、Nr1d1、Fst表达趋势与RNA-seq结果趋势一致。此分析提示PoRV感染小鼠肠上皮细胞后可能通过细胞增殖相关基因的高表达或其信号通路的激活进行受损的肠上皮的修复。
