Long non-coding RNAs (lncRNAs) are a new arm of gene regulatory mechanism as discovered by sequencing techniques and follow-up functional studies. The lncRNAs regulation of pseudorabies virus (PRV) infection has rarely been reported so far. Using RNA sequencing analysis, 225 lncRNAs with significant altered expressions in 3D4/21 cells infected with PRV (ZJ01) were identified. Five lncRNAs upregulated in PRV-infected cells were verified in cells infected with different PRV strains by qRT-PCR. By down- and up-regulation of lnc641, the accelerating effect of lnc641 on PRV replication was confirmed. Furthermore, we found that lnc641 regulated PRV replication by inhibiting the JAK-STAT1 pathway. This study suggests that lnc641 could be a new host factor target for developing antiviral therapies against PRV infection.
长链非编码 RNA（lncRNAs）是测序技术和后续功能研究发现的基因调控机制的新分支。迄今为止，关于 lncRNAs 对伪狂犬病病毒（PRV）感染的调节作用鲜有报道。通过 RNA 测序分析，在感染 PRV（ZJ01）的 3D4/21 细胞中鉴定出 225 个表达显著改变的 lncRNAs。通过 qRT-PCR 在感染不同 PRV 株的细胞中验证了上调的 5 个 lncRNAs。通过下调和上调 lnc641，证实了 lnc641 对 PRV 复制的加速作用。此外，我们发现 lnc641 通过抑制 JAK-STAT1 通路来调节 PRV 复制。本研究表明，lnc641 可能成为针对 PRV 感染开发抗病毒治疗的新宿主因子靶标。
