Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis was also carried out to reveal the over-expressed pathways in the EmbA_KD infection group, namely, oxidative phosphorylation, vascular endothelial growth factor, signaling pathway, and FoxO signaling pathway and downregulated pathways, such as TNF/C-type lectin/Toll-like receptor/mitogen-activated kinase signaling pathways (Figures 6F, G). This evidence concerns the gene TNF and infection.
