Endothelium dysfunction induced by reactive oxygen species (ROS) is an important initial event at the onset of myocardial ischemia/reperfusion in which the Egr-1 transcription factor often serves as a master switch for various damage pathways following reperfusion injury. We hypothesized that an intracellular ROS/MAPK/Egr-1 signaling pathway is activated in cardiac microvascular endothelial cel...
Although it is well established that members of the Egr family of transcription regulatory factors are induced in many neuronal plasticity paradigms, it is still unclear what role, if any, they play in this process. Because NGF stimulation of pheochromocytoma 12 cells elicits a robust induction of Egr family members, we have investigated their role in mediating long-term effects elicited by NGF...
Egr-1 (early growth response gene-1) is an immediate early gene encoding a zinc finger motif-containing transcription factor. Upon cross-linking of BCR, mature B cells undergo proliferation with an increase in Egr-1 message. Immature B lymphoma cells that express Egr-1 message and protein constitutively are growth inhibited when Egr-1 is down-regulated by negative signals from BCR or by antisen...
Activating the protein-tyrosine kinase activity of v-Fps leads to the rapid transcriptional activation of the Egr-1 gene, which encodes a mitogen-responsive transcription factor. Activation of Egr-1 by v-Fps was insensitive to protein kinase C depletion, suggesting that a protein kinase C-independent signal activated by v-Fps leads to the induction of Egr-1. Expression of v-Fps in transient exp...
OBJECTIVE Angiopoietin-1 (Ang-1) is an important regulator of angiogenesis in endothelial cells. It promotes migration, proliferation, and differentiation of cells, although the regulating factors involved in these processes remain unclear. In this study, we evaluated the contribution of the transcription factor early growth response-1 (Egr-1) to Ang-1-induced angiogenesis in human umbilical ve...
Transcription of early growth response gene-1 (Egr-1) is required for macrophage differentiation. Since granulocyte-macrophage colony-stimulating factor (GM-CSF) induces macrophage proliferation as well as the transcription of Egr-1 mRNA, we characterized the induction of Egr-1 protein in murine peritoneal macrophages following treatment with GM-CSF. As determined by Western blot analysis, the ...

EGR: erythema gyratum repens SLE: systemic lupus erythematosus INTRODUCTION Bullous lupus erythematosus is an autoantibodymediated subepidermal blistering disease that occurs in patients with systemic lupus erythematosus (SLE). Erythema gyratum repens (EGR) is a clinical diagnosis characterized by a wood grain pattern of centrifugally migrating erythematous plaques with fine leading scale. Alth...
PURPOSE EGR-1 is an immediate early gene with diverse functions that include the suppression of growth. EGR-1 is down-regulated many cancer cell types, suggesting a tumor suppressor role, and may critically involve the p53 pathway. The aim of this work was to measure the expression of EGR-1 and the p16/INK4a/ARF-Mdm2-p53 pathway status in fresh human gliomas. EXPERIMENTAL DESIGN Thirty-one hu...
The decrease of ASPP1 (Apoptosis-Stimulating Protein of p53 1), a known p53 activator, has been linked to carcinogenesis and the cytotoxic resistance in various cancers, yet the underlying mechanisms of ASPP1 expression and its complex functions are not yet clear. Here, we report that ASPP1 forms an inter-regulatory loop with Early Growth Response 1 (EGR-1), and promotes apoptosis via inhibitin...
