Description
Soyfoods have been drawn the interrest in the roles that reducing risk of cardiovascular disease. Among various components, isoflavones have been come to the attention as beneficial soy ingredients. To evaluate the effectiveness of isoflavone content in dietary soybean (Glycine max) on modulating lipid metabolism, hepatic gene expressions involved in lipid metabolism were analyzed in rats. An isoflavone-rich cultivar (Yukipirika) and a conventional cultivar (Fukuyutaka) were employed. A principal component analysis (PCA) of microarray data was used to summarize characteristics of the experimental groups. As a result, the characteristics of the diets were largely explained by the first principal component (PC1). Soybean content in the diets distinctly separated in PC1. In contrast, isoflavone content had little effect on the mRNA expression.
