Figure 3. Normal NF-κB activation in PML^−/− cells.

(A) WT and PML^−/− MEFs were stimulated with TNFα (10 ng/ml) for the indicated times and analysed by immuno-blotting with the indicated antibodies. (B) Nuclear translocation of p65 in TNFα treated WT and PML^−/− MEFs was assessed by confocal microscopy.
