IFN induces NF-κB activation in diverse cell types. (A) EMSA on nuclear extracts from IFN-treated (5,000 units/ml rat IFNβ for 30 min) murine 3T3 fibroblasts and rat intestinal IEC-6 cells, or IFN-treated (5,000 units/ml IFNCon1 for 30 min) human CaKi and HepG2 cells. (B) Murine L929 cell transfectants expressing empty vector (EV) or two independent wild-type huIFNAR-1 (WT) transfectants (29) were treated with IFNCon1 (5,000 units/ml) for 30 min before gel shift analysis with a NF-κB probe.
