MiR-21 (A) and miR-1 (B) expression were assessed in OVA and Aspergillus fumigatus asthma models. (C) MiR-21 expression was determined in IL-4 lung transgenic mice. The relative expression levels were determined by qRT-PCR normalized to snoRNA202; *, p < 0.05; **, p < 0.01, ***, p < 0.001; ****, p < 0.0001. Data are represented as mean ± S.E.M; n = 3–7 mice per group; data representative of 3 experiments.
