KEGG analysis further indicated the involvement of SFRPs in various pathways, including the Wnt signaling pathway, proteoglycans in cancer, signaling pathways regulating stem cell pluripotency, PI3K-Akt signaling pathway, CRC, AMPK signaling pathway, mRNA surveillance pathway, and other pathways related to CRC (Fig. 3C). Here, AKT1 is linked to cancer.
