Fig. 5From: Genetic deletion of MMP12 ameliorates cardiometabolic disease by improving insulin sensitivity, systemic inflammation, and atherosclerotic features in miceReduced atherosclerotic plaque size and collagen content in aortas of DKO mice. Female LdlrKO and DKO mice were fed a HFSC diet for 20 weeks. (A) Oil red O staining of en face aortas and quantification of atherosclerotic lesions in the (B) total aorta and (C) aortic arch. (D) Oil red O staining of aortic valve sections (magnification, 5X) and (E) plaque area quantification. (F) Masson´s Trichrome staining of aortic valve sections (magnification, 5X) and quantification of (G) collagen-positive area and (H) necrotic core. Data represent mean values (n = 8–11) ± SD. *p < 0.05; ** p ≤ 0.01Back to article page
