title: Inhibition of atherosclerosis in low-density lipoprotein receptor-negative mice by sesame oil.
abstract: Diet has profound effects on the development of atherosclerosis. Fatty acid composition, antioxidants, and other components such as lignans have major effects on the atherosclerotic process. Sesame oil has both mono- and polyunsaturated fatty acid constituents in equal proportions. In addition, it also has high levels of numerous antioxidants and inducers of peroxisome proliferator-activated receptor. The objective of this study was to determine the anti-atherosclerotic effects of sesame oil. In this study, male low-density lipoprotein (LDL) receptor (LDLR) -/- mice were fed atherogenic diet or atherogenic diet reformulated with the same level of sesame oil (sesame oil diet). Plasma lipids and atherosclerotic lesions were quantified after 3 months of feeding. Sesame oil-containing diet significantly reduced the atherosclerotic lesion formation and plasma cholesterol, triglyceride, and LDL cholesterol levels in LDLR -/- mice. These findings suggest that sesame oil could inhibit atherosclerosis lesion formation effectively, perhaps because of the synergistic actions of fatty acid and nonsaponifiable components.
