Fig. 1. ATF3 is upregulated in mice and human fibrotic liver.
a, b The expression of ATF3 and α-SMA was assessed by qRT-PCR analysis and immunoblot in livers from mice treated with CCl4 for 8 weeks. c The expression of ATF3 was examined in CCl4-induced fibrotic livers using IHC staining, 10× and 40× magnification. d, e The expression of ATF3 and α-SMA was assessed by qRT-PCR analysis and immunoblot in livers from mice that underwent BDL for 21 days. f The expression of ATF3 was examined in BDL-induced fibrotic livers using IHC staining, 10× and 40× magnification. g, h The expression of ATF3 was assessed by qRT-PCR analysis and immunoblot in liver samples of healthy people and fibrotic patients. The data were expressed as the mean ± SD for at least triplicate experiments, GAPDH was used as an internal control; *p < 0.05.
