pubmed:abstractText |
Macrophages accumulated in the arterial intima play an important role in the development of atherosclerosis by producing a large number of proinflammatory cytokines which accelerate the disease. Recent studies show that adipophilin might be involved in inflammatory processes in macrophages. In this study, we observe the effect of adipophilin on proinflammatory cytokine expression and secretion in THP-1 macrophages. SiRNA and adipophilin gene overexpression mediated by an pEGFP-C3 vector were used to observe the effect of adipophilin on proinflammatory cytokines in THP-1 macrophages in vitro. Realtime PCR and enzyme-linked immunosorbent assay (ELISA) were applied to detect the production of tumor necrosis factor alpha (TNF-alpha), monocyte chemoattractant protein 1 (MCP-1), and interleukin-6 (IL-6). It was found that acetylated low-density lipoprotein (AcLDL), pioglitazone [a peroxisome proliferator-activated receptor gamma (PPARgamma) agonist] increased adipophilin expression in macrophages, while glucose had no such affect. It was also shown that adipophilin augments TNF-alpha, MCP-1, and IL-6 expression in AcLDL induced macrophages. Our results suggest that adipophilin augment inflammation in macrophages, which might be one role of adipophilin in atherosclerosis.
