Figure 2

Pulmonary arginase activity and arginase isozyme expression in CAP+O 3 -exposed mice and filtered air controls. Total arginase activity in FA- and CAP+O3-exposed model OVA/PBS (□) and OVA/OVA (■) mice in the sub-acute (A) and chronic (B) models. Western blotting and quantification of arginase 1 and actin loading controls in the sub-acute (C) and chronic (D) models (*P < 0.05, **P < 0.01, ***P < 0.001, (n)). E) Correlation between levels of arginase 1 expression in the OVA/OVA mice in the sub-acute model and CAP exposure concentration (Spearman ρ = 0.6219; P = 0.013, n = 11 independent exposure dates).
