Abstract

BPOZ2 is a tumor suppressive mediator in PTEN signaling pathway and plays an important role in cell proliferation. In this study, we investigated the physiology functions of BPOZ2 in CCl4-induced liver injury and hepatocyte proliferation afterwards. After acute CCl4 administration, BPOZ2 null mice exhibited delayed liver injury and impaired hepatocyte proliferation, which was accompanied by altered kinetics of CYP2E1 protein expression, compromised cyclin D1 expression and shortened duration of ERK activation. These results for the first time define that BPOZ2 is an important regulator involved in the injury and repair process induced by acute CC14 administration in mouse liver.
