TNF and toxoplasmosis: On the other hand, the KEGG pathways of the 4W candidate genes were mainly related to glycosaminoglycan biosynthesis–chondroitin sulfate/dermatan sulfate, leishmaniasis, IL-17 signaling pathway, Toll-like receptor signaling pathway, NF-kappa B signaling pathway, toxoplasmosis, tumor necrosis factor (TNF) signaling pathway, osteoclast differentiation, cell cycle, and alcoholic liver disease (Figure 4F).
