abstract：:Nuclear factor-kappa B (NF-kappaB) plays an important role in UV-induced skin tumorigenesis. Activation of NF-kappaB by UV-irradiation is composed of two phases. The early phase culminates with maximal levels of DNA binding ability at 4 h postirradiation and is dependent on translational inhibition. The late-phase act...
