Abstract
Citrus fruit compounds have many health-enhancing effects. In this study, using a luciferase ligand assay system, we showed that citrus auraptene activates peroxisome proliferator-activated receptor (PPAR)-α and PPARγ. Auraptene induced up-regulation of adiponectin expression and increased the ratio of the amount of high-molecular-weight multimers of adiponectin to the total adiponectin. In contrast, auraptene suppressed monocyte chemoattractant protein (MCP)-1 expression in 3T3-L1 adipocytes. Experiments using PPARγ antagonist demonstrated that these effects on regulation of adiponectin and MCP-1 expression were caused by PPARγ activations. The results indicate that auraptene activates PPARγ in adipocytes to control adipocytekines such as adiponectin and MCP-1 and suggest that the consumption of citrus fruits, which contain auraptene can lead to a partial prevention of lipid and glucose metabolism abnormalities.
