MAP3K7 and hepatocellular carcinoma: Accordingly, we generated the HA-tagged constructs expressing the full-length TAK1 (TAK1), and the truncated forms of TAK1 including its kinase domain (TAK1-N, 1-300AA) and the C-terminal domain (TAK1-C, 301-579AA), and then co-transfected each one of these constructs respectively with FLAG-tagged 14-3-3ε into HCC cells.
