Chronic exposure of mice to UVB induces activation of NF-κB and IKKα, and degradation of IκBα. The activation of NF-κB (A), IKKα (B) or degradation of IκBα (C) was determined using western blot analysis. A representative blot is shown from three independent experiments with almost identical observations. Equivalent protein loading was confirmed by probing stripped blots for β-actin as shown. The relative density (arbitrary) of each band after normalization for β-actin is shown under each immunoblot.
