Mangiferin promotes macrophage cholesterol efflux and protects against atherosclerosis by augmenting the expression of ABCA1 and ABCG1

Figure 6. PPARγ mediates the positive effects of mangiferin on the expression of ABCA1/G1 and LXRα. RAW264.7 macrophage-derived foam cells were pretreated with 25 μM rosiglitazone (AC) or transfected with 20 nM PPARγ siRNA (DF) and then incubated with mangiferin (20 μM) for 24 h. RT-PCR and western blot analyses were performed to assess the mRNA and protein levels, respectively, of ABCA1/G1, LXRα and PPARγ. All results were obtained from three independent experiments, each performed in triplicate. Data are expressed as the mean ± SEM (n =3/group). *P < 0.05 vs. control group; #P < 0.05 vs. mangiferin only group.
