In KEGG enrichment, the 36 genes were considerably enriched in cellular senescence, PI3K Akt signalling pathway, viral carcinogenesis, Rap1 signalling pathway, TGF-β signalling pathway, MAPK signalling pathway, relaxin signalling pathway, miRNAs in cancer, and apelin signalling pathway (Figure 7(d)). This evidence concerns the gene TGFB1 and cancer.
