HOXB5 and hepatocellular carcinoma: To investigate whether cytokines or chemokines were involved in HOXB5-mediated HCC metastasis, a human Cytokines & Chemokines PCR Array was applied to compare cytokines and chemokines expression in PLC/PRF/5-HOXB5 cell and PLC/PRF/5-control cell or MHCC97H-shHOXB5 cell and MHCC97H-shcontrol cell.
