MUC5AC and MUC5B mRNA levels at 1 and 21 days after exposure. Taqman quantitative real-time RT-PCR was used to measure changes in whole lung mRNA levels of A) MUC5AC and B) MUC5B. Values are means ± SEM (n = 5–7 animals/group). *p < 0.05, **p < 0.01, ***p < 0.001 as compared to the control group of the same genotype or as indicated.
