Seven glycogenes: c1galt1, galnt3, gcnt3, man1a1, mgat4a, mgat5, mgat5b, were selected to identify the results of the PCR Array by qRT-PCR in human HCC cell lines (Hep3B, MHCC97L, MHCC97H, HCCLM3) and their orthotopic xenograft tumors. The gene discussed is MGAT5B; the disease is hepatocellular carcinoma.
