The transcription factors Sp1, Sp3, and Egr-1 bind with their zinc finger DNA-binding domains to GC-rich sequences in the regulatory regions of their target genes. The similarity of the DNA-binding sites of Sp1, Sp3, and Egr-1 has triggered the hypothesis that they compete for the same DNA-binding site. We have investigated the specificity of(More)
Substance P is a member of the tachykinin family of neuropeptides that plays an important role in pain transmission, neurogenic inflammatory diseases and the adaptive response to stress. Substance P exerts its biological activities via binding to a G-protein coupled receptor of the neurokinin (NK) receptor family. Here, we show by Western blot experiments(More)
Arsenite is a human carcinogen that may induce cancer in skin, liver, kidney, bladder or lung. Arsenite executes its toxic effects by the induction of signaling cascades. In particular, the activation of the stress-induced protein kinase c-Jun N-terminal protein kinase and p38 and the phosphorylation and activation of the transcription factor c-Jun have(More)
Activation of extracellular signal-regulated protein kinase (ERK) triggers the biosynthesis of Egr-1, a zinc finger transcription factor. Likewise, the tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA) strongly upregulates Egr-1 biosynthesis. Here, we have analyzed the genetic elements involved in the regulation of Egr-1 gene transcription by ERK(More)
