Depletion of AhR and Arnt increases RelB levels in Poly I: C-exposed BEAS- 2B cells. Cells were transfected with siRNA against AhR (siAHR), Arnt (siARNT) or non-targeting control siRNA (siNT), and exposed to 10 μg/ml Poly I:C for 2 and 4 h. Intracellular protein levels of RelB and β-actin were detected by Western blotting as described under “Materials and methods”. The figure displays representative blots of RelB levels in unexposed cells (A) and Poly I:C-exposed cells (B). The graph depicts relative changes in RelB (B) compared to β-actin quantified by densitometric analysis of the Western blots. The results are expressed as mean ± SEM (n = 3). *Significantly different from unexposed controls; †Significantly different from cells transfected with non-targeting siRNA.
