- Abstract
Glaesserella parasuis (G. parasuis) is the pathogen of Glässer's disease in pig herds, which can cause severe inflammatory responses. However, at present, the pathogenic mechanism of G. parasuis is not very clear. LncRNAs can regulate the expression of mRNA in a variety of ways, thereby causing host cells to produce a variety of functional changes in response to bacterial infection. Here, we detected the changes in lncRNAs and mRNAs of 3D4/21 cells after G. parasuis CY1201 strain (serotype 13) infection. A total of 876 lncRNAs and 2166 mRNAs were differentially expression in 3D4/21 cells after G. parasuis infection. GO and KEGG enrichment analysis showed that the differentially up-regulated lncRNA target genes were mainly involved in the response to extracellular stimuli, cell receptor signaling pathways and chemokine signaling pathways. The differentially down-regulated lncRNA target genes were mainly involved in ERK1/ERK2 cascade reaction and adhesion junctions. 44 lncRNAs were screened that might be related in inflammation. CeRNA regulatory network of the top five difference inflammation-related lncRNAs showed that the up-regulated lncRNA group involved 5 lncRNAs, 50 miRNAs and 49 mRNAs. Meanwhile, there were 26 miRNAs and 36 mRNAs in the top five down-regulated lncRNA group. Our results contribute to understand the basic role of lncRNAs in 3D4/21 cells during G. parasuis infection, and lay the foundation for following research., (Copyright © 2022 Elsevier Ltd.
