RENBP and Salmonella Infections: The KEGG pathway analysis revealed the pathways most enriched with DEGs in the skin of yellow catfish under transport stress (Figure 7), which included the Toll-like receptors (TLRs) signaling pathway, the NOD-like receptors (NLRs) signaling pathway, salmonella infection, cytokine-cytokine receptor interaction, and the AGE-RAGE signaling pathway related to diabetic complications.
