According to the results of KEGG pathway analysis, these candidate genes were enriched in several signalling pathways, such as Regulation of lipolysis in adipocytes, Ras signalling pathway, Biosynthesis of antibiotics, Insulin resistance, Pantothenate and CoA biosynthesis, TNF signalling pathway, Melanoma, Glioma, Asthma and Regulation of lipolysis in adipocytes were significantly enriched (p < 0.05) (Table S5). The gene discussed is TNF; the disease is glioma.
