KRT20 and colorectal carcinoma: Gene enrichment analysis (GEA) revealed enrichment of prognostic gene signatures (epithelial high-risk [EpiHR]14 and one of the five clinically relevant CRC subsets [CRISB]21) and signatures derived from metastasis-initiating cells in mouse models (high-relapse cells [HRC] KRT20−/+)14 in the RECs (Figure 1E).
