We subsequently performed GO and KEGG enrichment analyses using the DAVID tool, which indicated that DKK1‐related signaling pathways included Wnt signaling, Wnt‐protein binding, cytokine activity, multicellular organism development, negative regulation of protein phosphorylation, mTOR signaling, and pathways in cancer (Figure 1D,E). The gene discussed is DKK1; the disease is cancer.
