Abstract:
Objective To investigate the effect of the asthmatic mice's contents of nuclear factorerythroid-2-related factor 2,Nrf2 and HO-1 reated with curcumin in lung tissue.Methods All 45 mice were divided into three teams randomly,the normal mice,the asthmatic mice and the curcumin mice group.We tested the expression of Nrf2 and HO-1 of three mice teams in lung by immunolfluorescence technique.We tested the protein contents of Nrf2 and HO-1 of the three teams in the lung tissue by Western blot.We tested the binding activity of Nrff2 and ARE of the three teams in lung by EMSA.Results The expression of Nrf2 and HO-1 in curcumin group was significantly higher than that in asthma group and normal control group by immunolfluorescence technique.There was no sigrnificant difference in content of cytoplasm Nrf2 protein in lung tissue between three groups by western blot(P ＞ 0.05).The content of nuclear Nrf2 and HO-1 protein in the lung tissue of the curcumin group was significantly higher than that in the other two groups,the difference is statistically significant (Nrf2,P ＜0.05;HO-1,P ＜0.01).The binding activity of Nrf2-ARE in lung tissue of curcumin group was significantly higher than that of asthma group and control group,with statistical significance(P ＜ 0.05).Conclusion Curcumin can increase the protein contents of the Nrf2 and HO-1 of mice and enhance the expression of them.
