HO-1 expression and its effects on HSC proliferation. (a) HO-1 mRNA expression was detected with real-time PCR after the cells were exposed to Hemin or ZnPP-IX. (b) The HO-1 protein level was detected using Western blotting. (c) Effect of HO-1 expression on HSC-T6 cell proliferation. The MTT results for the normal, Hemin-treated, and ZnPP-IX-treated groups were 1.034 ± 0.003, 0.867 ± 0.023, and 1.161 ± 0.015, respectively. ^∗P < 0.01 vs. the normal group; ^▲P < 0.05 vs. the Hemin-treated group.
