KEGG pathway analysis indicated significant enrichment in pathways including the PI3K‐Akt signalling pathway, colorectal cancer, apoptosis, Wnt signalling pathway, Jak–STAT signalling pathway, MAPK signalling pathway, TGF‐β signalling pathway, HIF‐1 signalling pathway, VEGF signalling pathway and AMPK signalling pathway (Figure 7D). Here, TGFB1 is linked to colorectal cancer.
