Prevention of arterial thrombotic diseases has a high priority in developed countries. An inappropriate diet is known to enhance the risks for acute thrombotic events, and nutritional products experimentally shown to be antithrombotic, might contribute beneficial effects. The present study forms part of a series of investigations into the antithrombotic effect of various foods and vegetables.

The impact of sesamin, episesamin and sesamolin (sesame lignans) on hepatic gene expression profiles was compared with a DNA microarray. Male Sprague-Dawley rats were fed experimental diets containing 0.2% sesamin, episesamin or sesamolin, and a control diet free of lignans for 15 days.

(+)-Sesamin, a furofuran class lignan, is widespread in vascular plants and represented by Sesamum spp. (+)-Sesamin has been of rapidly growing interest because of its beneficial biological effects in mammals, but its biosynthesis and physiological roles in plants remain to be clarified. It is speculated to be synthesized from (+)-pinoresinol by means of (+)-piperitol by formation of two methylenedioxy bridges mediated by two distinct Sesamum indicum cytochrome P450 (SiP450) proteins.
