The KEGG results exhibited that the DEGs were primarily connected with cytokine-cytokine receptor interaction, human papillomavirus infection, protein digestion and absorption, rheumatoid arthritis, ECM-receptor interaction, the Wnt signaling pathway, breast cancer, chemokine signaling pathways, the IL-17 signaling pathway, viral protein interaction with cytokine and cytokine receptor and the NF-kappa B signaling pathway (Figure 4K). This evidence concerns the gene IL17A and breast cancer.
