Through certain threshold screening and GO/KEGG enrichment analysis, we obtained some potential cancer-related pathways, such as interleukin-4 and interleukin-13 signaling: R- HSA:6785807, class I MHC-mediated antigen processing and presentation: R- HSA:983169, collagen biosynthesis and modifying enzymes: R- HSA:1650814, and activation of the prereplicative complex: R- HSA:68962. The gene discussed is IL4; the disease is cancer.
