Early growth response-1 (Egr-1) and the non-receptor protein tyrosine kinase (c-Abl) are 2 response genes that can act as regulators of cell growth and apoptosis in response to stress. Both Egr-1 and c-Abl regulate cell proliferation and survival in different types of cancer cells. To study the effect of overexpression of EGR-1 on the activity of c-Abl in prostate cancer cells, human PC-3 and L...

Early growth response-1 (Egr-1) is a Cys2-His2-type zinc-finger transcription factor. A broad range of extracellular stimuli is capable of activating Egr-1, thus mediating growth, proliferation, differentiation or apoptosis. Egr-1 is, therefore, participating in the progression of a variety of diseases such as atherosclerosis or cancer. Functional response elements connect Egr-1 to signal trans...

The early growth response-1 gene (EGR-1) is induced by a wide range of stimuli in diverse cell types; however, EGR-1-regulated genes display a highly restricted pattern of expression. Recently, an overlapping Sp1.EGR-1 binding site has been identified within the interleukin-2 (IL-2) gene promoter directly upstream of the binding site for the nuclear factor of activated T cells (NFAT). We used t...

The EGR-1 gene is an immediate early response gene encoding a zinc finger DNA-binding protein. The present studies have examined the regulation of EGR-1 gene expression in human U-937 monocytic leukemia cells treated with granulocyte-macrophage colonystimulating factor (GM-CSF). The results demonstrate that GM-CSF rapidly and transiently increases EGR-1 gene expression in U-937 cells. Similar f...

Long-term exposure to arsenic, an environmental contaminant, leads to increased risks of cancers. In the present study, we investigated the sequential regulation of Elk-1 and Egr-1 on As3+-induced GADD45α, an effector of G2/M checkpoint. We found that As3+ transcriptionally induced both Elk-1 and Egr-1, and NF-κB binding site was necessary for As3+-induced Egr-1 promoter activity. However, spec...

The proapoptotic BH3-only protein Bim is a crucial regulator of neuronal apoptosis. Previous studies have indicated the involvement of the c-Jun, FOXO1/3a, and B/C-Myb transcription factors in the regulation of Bim during neuronal apoptosis. However, the mechanism underlying the transcriptional regulation of Bim in activity deprivation-induced neuronal apoptosis has remained unclear. The presen...

FasL expressed in tumor cells plays an important role in the escape from immune surveillance by inducing apoptosis in T-cells bearing Fas. Since the Fas/FasL signaling pathway requires transcriptional induction of the FasL gene, elucidation of the precise mechanisms underlying regulation of FasL gene expression may provide useful molecular insights on tumor progression. We and others (Shin, E. ...

Prostate cancer is the most prevalent malignancy and the second leading cause of cancer mortality in men. Early growth response gene-1 (EGR-1) plays a crucial role in the development and progression of prostate cancer. The presented data show that EGR-1 differs in cellular localization in benign cells compared with malignant prostate cells and that this localization is critical for the transcri...

OBJECTIVES The excess proliferation of vascular smooth muscle cells (VSMCs) and the development of intimal hyperplasia is a hallmark of vein graft failure. This study aimed to verify that a single intraoperative transfection of early growth response gene-1 (Egr-1) decoy oligonucleotide (ODN) can suppress vein graft proliferation of VSMCs and intimal hyperplasia. METHODS In a rabbit model, jug...

Early growth response gene (Egr)-2 is important for the maintenance of T cell homeostasis and controls the development of autoimmune disease. However, the underlying mechanisms are unknown. We have now discovered that Egr-2, which is induced by TGF-β and IL-6, negatively regulates the expression of IL-17, but not IL-2 or IFN-γ, in effector T cells. In the absence of Egr-2, CD4 T cells produce h...
