BACKGROUND: Previous reports have suggested that advanced glycation end products
(AGEs) participate in the pathogenesis of diabetic macroangiopathy. Our previous
study have found that AGEs can increase the lipid droplets accumulation in aortas
of diabetic rats, but the current understanding of the mechanisms remains
incomplete by which AGEs affect lipids accumulation in macrophages and accelerate
atherosclerosis. In this study, we investigated the role of AGEs on lipids
accumulation in macrophages and the possible molecular mechanisms including
cholesterol influx, esterification and efflux of macrophages. METHODS: THP-1
cells were incubated with PMA to differentiate to be macrophages which were
treated with AGEs in the concentration of 300 ?g/ml and 600 ?g/ml with or without
anti-RAGE (receptor for AGEs) antibody and then stimulated by oxidized-LDL
(oxLDL) or Dil-oxLDL. Lipids accumulation was examined by oil red staining. The
cholesterol uptake, esterification and efflux were detected respectively by
fluorescence microscope, enzymatic assay kit and fluorescence microplate.
Quantitative RT-PCR and Western blot were used to measure expression of the
moleculars involved in cholesterol uptake, synthesis/esterification and efflux.
RESULTS: AGEs increased lipids accumulation in macrophages in a
concentration-dependent manner. 600 ?g/ml AGEs obviously upregulated oxLDL
uptake, increased levels of cholesterol ester in macrophages, and decreased the
HDL-mediated cholesterol efflux by regulating the main molecular expression
including CD36, Scavenger receptors (SR) A2, HMG-CoA reductase (HMGCR), ACAT1 and
ATP-binding cassette transporter G1 (ABCG1). The changes above were inversed when
the cells were pretreated with anti-RAGE antibody. CONCLUSIONS: The current study
suggest that AGEs can increase lipids accumulation in macrophages by regulating
cholesterol uptake, esterification and efflux mainly through binding with RAGE,
which provide a deep understanding of mechanisms how AGEs accelerating diabetic
atherogenesis.
