The effect of adiponectin on LXRα expression. The RAW 264.7 macro1phages were incubated with 1 µg/mL, 5 µg/mL and 10 µg/mL adiponectin for 24 h respectively, and macrophages were incubated with 5 mg/mL BSA for 24 h or with 10 µg/mL adiponectin for 0 h, 6 h, 12 h, 24 h, respectively. A and B: LXRα gene expression was measured by real-time quantitative PCR. C and D: LXRα protein expression was measured by Western blot analyses. Data are the means ± SD of three independent experiments. *P < 0.05 compared with the control group.
