The results of the KEGG enrichment analysis show (Figure 4D) that these DEGs were more enriched in the KEGG pathways, mainly including the Toll-like receptor signaling pathway, salmonella infection, phenylalanine tyrosine and tryptophan biosynthesis, p53 signaling pathway, neuroactive ligand-receptor interactions, melanogenesis, MAPK signaling pathway, GnRH signaling pathway, ErbB signaling pathway, and cytokine–cytokine receptor interactions in these signaling pathways (p < 0.05). Here, GNRH1 is linked to Salmonella Infections.
