tokens: In U937 and Jurkat T lymphoid cells , the inducibility of the different hybrid promoters by TNF-alpha or phorbol ester varied in a cell type- and promoter context-specific manner ; the levels of gene activity of NF-kappa B -containing plasmids correlated directly with induction of NF-kappa B DNA-binding activity .
