Role of Myc in hepatocellular proliferation and hepatocarcinogenesis.

ABSTRACT:

Background & aims

Myc is involved in cell growth, proliferation, apoptosis, energy metabolism, and differentiation. Whether it is essential for hepatocellular proliferation and carcinogenesis is unclear due to a lack of an efficient hepatocyte-specific Myc disruption model. This study used a novel genetic model to investigate the involvement of Myc in hepatocellular proliferation and hepatocarcinogenesis in mice.

Methods

Temporal hepatocyte-specific Myc disruption was achieved by use of the tamoxifen-inducible Cre-ER(T2) recombinase system under control of the serum albumin promoter. Hepatocyte proliferation was assessed by administering peroxisome proliferator-activated receptor α (PPARα) agonist Wy-14,643. A diethylnitrosamine-induced liver cancer model was used to evaluat
