Early growth response (EGR) transcription factors link initial cytoplasmic events to long-term alterations of cellular gene expression and are induced by various stimuli. To test their roles in cell physiology, we constructed adenoviral recombinants encoding NGFI-A binding protein 2 (NAB2, a repressor of EGR1, EGR2, and EGR3), EGR1, NAB-insensitive EGR1(I293F) (EGR1∗), EGR2, and the NAB-binding, repressive domain 1 (R1) of EGR1. These viruses regulated EGR-dependent expression of GFP and luciferase reporter genes in heterologous expression assays. Infection of a myoblast cell line with EGR1 and EGR1∗ adenovirus induced the endogenous gene for platelet-derived growth factor A chain (PDGF-A). In addition, in neuroblastoma cells, the two novel EGR1 target genes EGR3 and NAB2 were identified by using adenoviral transfer of EGR1 and EGR1∗. Our results demonstrate that recombinant adenovirus is useful to regulate heterologous and endogenous EGR target gene expression, and suggest that EGR transcription factors can autoregulate themselves.
