Abstract/OtherAbstract:
1. Effects of sesamin and episesamin (an epimer of sesamin) on lipid metabolism, in particular cholesterol metabolism, were examined in normocholesterolaemic and hypercholesterolaemic stroke-prone spontaneously hypertensive rats (SHRSP). 2. In normocholesterolaemic SHRSP fed a regular diet, both sesamin and episesamin significantly increased the concentration of serum total cholesterol, which was due to an increase of high density lipoprotein (HDL) subfraction rich in apoE (apoE-HDL). In addition, both substances effectively decreased serum very low density lipoprotein (VLDL). In the liver, only episesamin significantly decreased the activity of microsomal acyl-CoA:cholesterol acyltransferase. 3. In hypercholesterolaemic SHRSP fed a high-fat and high-cholesterol diet (HFC diet), only episesamin improved serum lipoprotein metabolism with an increase in apoA-I and a decrease in apoB. In the liver, both sesamin and episesamin significantly suppressed cholesterol accumulation. Interestingly, only episesamin significantly increased the activity of microsomal cholesterol 7alpha-hydroxylase. 4. These results indicate that sesamin may be effective in preventing cholesterol accumulation in the liver. In comparison with sesamin, episesamin may be effective in the regulation of cholesterol metabolism in the serum and liver.
