We demonstrate that atherosclerotic plaque size in the aortic sinus of SR-B1 KO mice after 20 weeks of HFCC is similar to that of LDLR KO and ApoE KO mice, while atherosclerosis in the descending aorta and coronary arteries is significantly higher in SR-B1 KO mice. This evidence concerns the gene SCARB1 and atherosclerosis.
