In this study, we examined the expression of human C/EBPdelta (NF-IL6beta) gene by epidermal growth factor (EGF) stimulation in human epidermoid carcinoma A431 cells. NF-IL6beta was an immediate-early gene activated by the EGF-induced signaling pathways in cells. By using 5'-serial deletion reporter analysis, we showed that the region comprising the -347 to +9 base pairs was required for EGF response of the NF-IL6beta promoter. This region contains putative consensus binding sequences of Sp1 and cAMP response element-binding protein (CREB). The NF-IL6beta promoter activity induced by EGF was abolished by mutating the sequence of cAMP response element or Sp1 sites in the -347/+9 base pairs region. Both in vitro and in vivo DNA binding assay revealed that the CREB binding activity was low in EGF-starved cells, whereas it was induced within 30 min after EGF treatment of A431 cells. However, no change in Sp1 binding activity was found by EGF treatment. Moreover, the phosphatidylinositol 3 (PI3)-kinase inhibitor (wortmannin) and p38(MAPK) inhibitor (SB203580) inhibited the EGF-induced CREB phosphorylation and the expression of NF-IL6beta gene in cells. We also demonstrated that CREB was involved in regulating the NF-IL6beta gene transcriptional activity mediated by p38(MAPK). Our results suggested that PI3-kinase/p38(MAPK)/CREB pathway contributed to the EGF activation of NF-IL6beta gene expression."xsd:string |
