Using conditional knockout technology, we show that AP-2alpha is essential for governing the balance between growth and differentiation in epidermis. In vivo, epidermis lacking AP-2alpha exhibits elevated expression of the epidermal growth factor receptor (EGFR) in the differentiating layers, resulting in hyperproliferation when the receptors are activated. Chromatin immunoprecipitation and promoter activity assays identify EGFR as a direct target gene for AP-2alpha repression, and, in the absence of AP-2alpha, this is manifested primarily in excessive EGF-dependent phosphoinositol-3 kinase/Akt activity. Together, our findings unveil a hitherto unrecognized repressive role for AP-2alpha in governing EGFR gene transcription as cells exit the basal layer and withdraw from the cell cycle. These results provide insights into why elevated AP-2alpha levels are often associated with terminal differentiation and why tumor cells often display reduced AP-2alpha and elevated EGFR proteins."xsd:string |
