BMDCs (A) and BMMs (B) cultured from 129 WT and stat1−/− mice were stimulated with poly I:C, LPS, IFN-α, IFN-β, or IFN-γ for 6 h, and then, Ch25h transcription was measured by real-time RT-PCR. Bars represent the mean (sd) of the response from three mice/strain for each treatment after normalization to 18S rRNA levels. The differences in expression of Ch25h between 129 WT and stat1−/− for BMMs and BMDCs for each treatment were statistically significant at P < 0.0001 (two-way ANOVA).
