Figure 4. Effects of the MR antagonist eplerenone on neointimal lesions in C57Bl/6J mice and 11β-HSD2−/− mice.
A) Eplerenone had no effect on systolic blood pressure in either normotensive C57Bl/6J or hypertensive 11β-HSD2−/− mice (p=0.6).
B) Eplerenone reduced neointimal area in both C57Bl/6J and 11β-HSD2−/− mice.
C) Eplerenone reduced macrophage content of lesions (staining for Mac-2), but did not affect smooth muscle (α-smooth muscle actin staining) or collagen (Picrosirius red) content.
Data are mean±SEM for n= 6/group and were analysed by two-way ANOVA and post hoc t tests when appropriate. ns indicates non-significant, ** indicates p<0.01.
