Figure 3. Anti-remodeling effects of minocycline in MCT-treated rats.
A, Representative micrographs show remodeling in pulmonary arteries of external diameter 25 to 50 μM stained with α-smooth muscle actin antibody and quantified for medial wall thickness (scale bar=100μm). B, Cumulative data of α-smooth muscle actin staining showing MCT caused significant increases in pulmonary medial wall thickness and this increase was significantly prevented by minocycline treatment. ‡p<0.001 vs. control and minocycline; ***p<0.001 vs. MCT (n= 6–7 rats/group). Data are represented as mean ± SEM, analyzed using one-way ANOVA with Newman-Keuls post hoc test. 2-way ANOVA showed significant interaction between MCT and minocycline on % medial wall thickness (p=0.0001).
