We further analyzed related genes (ALB, AFP, CTCF, MET, TP53 and PIK3CA) in human normal liver stem, hepatocellular cancer (HCC) cell lines, gastrointestinal cancer (GI) cell lines and normal skin fibroblasts cell line by using RT-PCR (Fig. 2BII). The gene discussed is ALB; the disease is hepatocellular carcinoma.
