Acute transcriptomic changes in murine RAW 264.7 cells following pseudorabies virus infection

Next-generation sequencing enables the evaluation of gene expression changes resulting from virus–host interactions at the RNA level. Pseudorabies virus (PRV) causes substantial economic loss in the swine industry. Recent research has revealed that PRV can be transmitted to and infect humans as well. To identify physiopathological and pathological responses post-PRV infection, we characterized transcriptomic changes in the murine RAW 264.7 cell line over the course of 36 h. In total, 156, 153, and 190 differentially expressed genes were identified at 2 h, 12 h, and 36 h, respectively. Seven differentially expressed genes (Trim27, Ccdc117, Mrps12, Ccl4, Cerkl, Ubald1, and Hmga1-rs1) were present across all treatment groups. Our findings expand our knowledge of gene regulation and immune response following PRV infection. These differentially expressed genes can subsequently improve our understanding of PRV pathogenesis.
