Suppression of postprandial hyperglycemia reduces lipogenic enzyme activities in the adipose tissues of normal rats. The present study investigated the expression of genes related to lipogenesis and insulin sensitivity in mesenteric adipose and epididymal adipose tissues to evaluate the effects of wheat albumin (WA) and a crude preparation of WA (CWA) with α-amylase inhibitory activity on lipid metabolism. Rats fed 2.5% WA, which had 12.7-fold inhibitory activity compared with CWA, exhibited reduced mRNA levels for G6PDH, ACO, ACS, PEPCK, and LPL in the mesenteric adipose, but not in the epididymal adipose tissue. Linear regression analyses showed that the gene expression levels of FAS, G6PDH, ACS, and LPL were reduced in dose-dependent manners in the mesenteric adipose tissue of rats fed the CWA diet. These results suggest that supplementation with CWA as well as WA reduces the expression of genes related to lipogenesis and insulin sensitivity in mesenteric adipose tissue.
