Figure 8. Changes of mRNA expression and protein expression levels of NF-κB and IκB in the lung at 21 and 42 days of the experiment. (A) Western blot assay of NF-κB and IκB at 21 days. (B) Western blot assay of NF-κB and IκB at 42 days. (C) The relative protein expression levels of NF-κB and IκB. (D) The relative mRNA expression levels of NF-κB and IκB. Data are presented with the mean± standard deviation (n=8). *p < 0.05, compared with the control group; **p < 0.01, compared with the control group.
