HO-1 mediates the stimulatory effects of TonEBP knockdown on the M2 phenotype. (A) RAW264.7 cells were treated with IL-4 (10 ng/ml) for 12 h. Expression of mRNA encoding IL-10, Arg-1, and CD206 was measured by quantitative RT-PCR. (B) Cells were transfected with scrambled [Scr (-)], TonEBP-targeting, or HO-targeting siRNA in the combinations indicated at the bottom of the panel for 24 h. The concentration of total siRNA was equalized by adjusting the concentration of Scr (-) siRNA. Transfected cells were then treated with IL-4 (10 ng/ml) for 12 h, and expression of mRNA encoding IL-10, Arg-1, and CD206 was measured by quantitative RT-PCR. Two-way ANOVA with Tukey's post-hoc test was used for multiple comparisons. Different letters indicate statistical differences at P < 0.05. Data (mean + SD) were from three independent experiments (n = 3) each with more than three replicates. AU, arbitrary units.
