Strikingly, among the top differentially expressed CRC EGC genes, we identified the two key murine CRC EGC marker genes Lcn2 and Timp1. Using gene set enrichment analysis, we found that human EGC populations differentiate along the same homeostatic and tumor pathogenesis pathway transcriptomic signatures (Fig. 8e) as seen in our murine EGCs (Fig. 2e). Here, LCN2 is linked to neoplasm.
