Objective: Nutritional deficiency during developmental stages could be associated with subsequent development of inflammation-related metabolic abnormalities. In this study, we examined the effects of a 3-d fast during the suckling-weaning transient period of rats, and subsequent intake of high-fat-high-sucrose (HF) and low-fat-high-starch (LF) diets in adulthood, on the expression of inflammatory genes in adipose tissue and peripheral leukocytes. Methods: Male Sprague-Dawley rats were deprived of food for 3 d during the suckling-weaning transient period, and were subsequently fed an HF or LF diet for 14 wk from 17 wk of age. Serum monocyte chemoattractant protein-1 (MCP-1) concentration and mRNA levels of inflammatory genes in mesenteric adipose tissues were assessed at 31 wk of age. The mRNA levels of inflammatory genes at 0 h and 2 h after oral glucose load at 30 wk of age in peripheral leukocytes were measured. Results: Fasting induced circulating MCP-1 protein in rats fed an LF diet but not an HF diet. The HF diet induced high mRNA levels of tumor necrosis factor-alpha, interleukin-1 beta, and 5100 proteins in peripheral leukocytes at 2 h after glucose load in fasted rats when compared with controls. Expression of CD11c, an activated macrophage marker, was induced in the fasted group given an HF diet during adulthood. Conclusions: Fasting rats during the suckling-weaning transient period and an HF diet intake during adulthood enhance inflammation by promoting the expression of inflammatory genes in adipose tissue and peripheral leukocytes.
