Perilla Oil Reduces Fatty Streak Formation at Aortic Sinus via Attenuation of Plasma Lipids and Regulation of Nitric Oxide Synthase in ApoE KO Mice

Consumption of n-3 polyunsaturated fatty acids (PUFA) is associated with a reduced incidence of atherosclerosis. Perilla oil (PO) is a vegetable oil rich in α-linolenic acid (ALA), an n-3 PUFA. In this study, antiatherogenic effects and related mechanisms of PO were investigated in atherosclerotic mice. Apolipoprotein E knockout (ApoE KO) mice (male, n = 27) were fed high-cholesterol and high-fat diets containing 10 % w/w lard (LD), PO, or sunflower oil (SO) for 10 weeks. Plasma triglyceride, total cholesterol, and low-density lipoprotein cholesterol concentrations reduced in the PO and SO groups compared to the concentrations in the LD group (P
