Basal mRNA expression level of epithelialcell adhesion molecule (EPCAM),CD44, THY1(also known as CD90), alanyl aminopeptidasemembrane (ANPEP, also known asCD13), Keratin19 (KRT19), and prominin-1 (PROM1, also known as CD133) was quantifiedin seven different HCC cell lines. The gene discussed is ANPEP; the disease is hepatocellular carcinoma.
