In line with the loss of transcriptional drivers of colonic differentiation, expression of general markers of colonic epithelial cells (VIL1, GPA33, MYO1A) (Fig. 3A), and markers of the major colonic cell lineages, enterocytes (FABP1, CDH17, KRT20, ALPI, ERBB3) and goblet cells (TFF3, MUC2, AGR2), were significantly downregulated in HG tumours (Fig. 3C, D). Here, GPA33 is linked to neoplasm.
