Further KEGG pathway analysis showed that significantly up-regulated DEGs in omental adipose tissue were highly related to categories including JAK-STAT signaling pathway, IL-17 signaling pathway, TNF signaling pathway, salmonella infection, amoebiasis, inflammatory bowel disease (IBD) and cytokine-cytokine receptor interaction, indicating those DEGs in omental adipose tissue might be involved in immune/inflammatory responses, pathological infection, and cell signaling. The gene discussed is TNF; the disease is Salmonella Infections.
