Unexpectedly, transactivation assays in transiently transfected Hep 3B cells showed p50 overexpression to markedly induce CRP transcription, acting in a region 3' to -86. In the presence of overexpressed p50, IL-1beta induced a 3-fold increase in CRP expression, and responses to IL-6 and to IL-6 plus IL-1beta were 4-fold greater than seen in cells without p50 overexpression. In contrast, overexpressed p65 abolished CRP induction by p50 and by cytokines. EMSA studies demonstrated that recombinant p50 bound to a nonconsensus kappaB site overlapping the proximal C/EBP binding site on the CRP promoter |
