Arrb2 deficiency enhances animal survival after BDL.
A, survival of wild type (WT) and Arrb2 knock-out (KO) mice (n = 25–30 per group) was observed from 5 to 30 days after BDL. *, p < 0.01, Arrb2 KO mice versus WT mice. B, livers were harvested from WT mice after 3 days of sham operation or BDL, and Arrb2 expression was determined by Western blot. *, p < 0.01 compared with WT sham control group.
