Transcriptional regulation of p65 iso5 on human IL-6-luc and TNFα-luc promoters. (a) Effect of p65 iso5 on natural human promoter IL-6-luc. HeLa cells were cotransfected with a luciferase reporter driven by promoter IL6-651luc; IL6-651luc mut κB; IL6-651luc mut GRE; IL-6-651luc mut AP-1; IL-6-651luc mut CRE; IL-6-651luc mut c/EBP and the plasmids p50, p65 and p65 iso5. (b) HeLa cells were cotransfected with a luciferase reporter driven by promoter TNFα-luc and the indicated plasmids. Cells were maintained in RPMI 1640 supplemented with Charcoal–dextran (CD) Fetal Bovine Serum (FBS). Data information: in (a, b), data are presented as mean ± SEM. *P < 0.001, in comparison to cells transfected with reporter plasmid.
