TP53 and cancer: Similarly, the KEGG analysis in cluster 2 also enriched some cancer‐related pathways, such as the Wnt signalling pathway, Basel cell carcinoma, signalling pathways regulating pluripotency of stem cells, pathways in cancer, cell adhesion molecules, transcriptional misregulation in cancer, hippo signalling pathway, ECM‐receptor interaction, proteoglycans in cancer, TGF‐β signalling pathway, choline metabolism in cancer, PI3K‐Akt signalling pathway and P53 signalling pathway.
