However, the expression of CEA (a cell adhesion protein anchored to the cell membrane by either a glycosylphosphatidylinositol moiety or a proteinaceous transmembrane and cytoplasmic domain, and highly expressed on many different cancers) and CK19 was not noted (Fig. 4E) suggesting that the primary liver tumors were hepatocellular carcinoma. The gene discussed is KRT19; the disease is hepatocellular carcinoma.
