Figure 5. LiCl (PWL) or atorvastatin(PWA)-induced attenuation of plaque size and the extent of macrophage (Mac-3) or matrix metalloproteinase-9 (MMP-9) immunoreactivity in the aortic arch (C and D) but not in the left common carotid artery (A and B).

Figure 5

PW denotes non-treated western-diet fed ApoE-/- mice with partial ligation-induced carotid atherosclerosis. Statistically significant p values from Mann-Whitney tests between groups are provided. MMP-9 immunoreactivity in the intima tends to be less extensive in the PWL group than in the other groups (B, # p = 0.083). Scale-bars, 100 µm.
