Compared with LW pigs, KEGG pathway analysis in the ILN of TC pigs revealed significant enrichment in endocytosis, ErbB signaling pathway, Toll-like receptor signaling pathway (RIPK1, TLR4, CD40, MAPK8, TLR8, IKBKG, MAP2K7, and PIK3CA) and Epstein-Barr virus infection (RIPK1, SLA-6, NFKBIE, PSMC6, CD40, MAPK8, ENTPD1, GSK3B, IKBKG, MAP2K7, POLR2B, and PIK3CA). This evidence concerns the gene EGFR and Epstein-Barr virus infection.
