CDX1 and neoplasm: Among the 17 overexpressed genes, CDX1 (caudal type homeobox 1) had the highest fold difference in tumor versus non-tumor tissues followed by SI (sucrase-isomaltase, aka alpha-glucosidase), KRT16 (keratin 16) and SERPINB5 (serpin peptidase inhibitor, clade B (ovalbumin), member 5).
