In the KEGG functional enrichment analysis, the main targets were osteoclast differentiation, IL‐17 signalling pathway, T cell receptor signalling pathway, programed cell death 1 expression and programed cell death ligand‐1checkpoint pathway in cancer, Th17 cell differentiation, Th1 and Th2 cell differentiation, C‐type lectin receptor signalling pathway and tumour necrosis factor(TNF)signalling pathway. This evidence concerns the gene TNF and cancer.
