Figure 3.

Effect of rifampicin and oxysterols on the mRNA expression of cholesterol efflux transporters in human primary monocyte–macrophages and foam cells in vitro measured with quantitative RT-PCR. Panels on the left (A, C, E) show the results of the experiments in macrophages and the panels on the right (B, D, F) display the results of the experiments in foam cells. The experiments were performed in four separate wells per experimental condition (n = 4). Data are presented as the mean + SD. *P < 0.05, **P < 0.01, and ***P < 0.001; ANOVA with Dunnett’s post hoc test.
