BACKGROUND Early growth response-1 (Egr-1) protein plays an important role in many human fibrotic diseases. Areca nut chewing is the most important risk factor of oral submucous fibrosis (OSF). METHODS Egr-1 protein expression in OSF was examined using antibody to Egr-1. Arecoline-induced Egr-1 expression and its signaling pathways were assessed by Western blot analyses in human buccal mucosa...
Hyperactivation of proliferative and growth promoting pathways underlies the progression of vessel remodeling, leading to vascular dysfunction. An upregulation of early growth response protein 1 (Egr-1), a zinc finger transcription factor has been observed in several models of vascular diseases. In the vasculature, Egr-1 expression can be induced by multiple hormonal, metabolic and external sti...
Egr-1, a mitogen-responsive transcription factor, is rapidly induced by v-Fps in the absence of protein synthesis. Thus, Egr-1 is a primary response to the protein-tyrosine kinase activity of v-Fps. To determine the v-Fps-responsive elements in the Egr-1 promoter, deletion mutants of the Egr-1 promoter were used in transient expression assays. A v-Fps expression vector was contransfected into N...
Cyclooxygenase (COX) inhibitors have antitumorigenic activity and increase the expression of the early growth response gene Egr-1, a tumor suppressor gene and transcription factor. In this study, we have investigated the gene regulatory and anti-invasive activity of two traditional nonsteroidal anti-inflammatory drugs (NSAID), sulindac sulfide and indomethacin. These compounds inhibited tumor c...
INTRODUCTION Peroxisome proliferator-activated receptor (PPAR)γ has been shown to exhibit anti-inflammatory and anti-catabolic properties and to be protective in animal models of osteoarthritis (OA). We have previously shown that interleukin-1β (IL-1) down-regulates PPARγ expression in human OA chondrocytes. However, the mechanisms underlying this effect have not been well characterized. The PP...
OBJECTIVE Lysophosphatidic acid (LPA), one component of oxidized low-density lipoprotein, is a potent bioactive phospholipid. Early growth response gene-1 (Egr-1), an important transcription factor, regulates expression of an array of genes involved in vascular diseases. Whether and how LPA regulates the transcriptional machinery of Egr-1 gene is unknown and is addressed in this study. METHOD...
The inhibitory effect of a specific small EGR-1 interfering RNA (siRNA) on cell proliferation and the expression of EGR-1 in human prostate carcinoma cell lines PC-3 and LNCaP was investigated. To knockdown Egr-1 expression, a siRNA targeting against Egr-1 was synthesized and transfected into PC-3 and LNCaP cells. The down-regulation of Egr-1 expression at both mRNA and protein levels were dete...
Hepatocyte growth factor/scatter factor (HGF) and the angiogenesis factors platelet-derived growth factors (PDGF), vascular endothelial growth factor (VEGF), and interleukin-8 (IL-8) are found in elevated concentrations in serum or tumor tissue of patients with head and neck squamous cell carcinomas (HNSCC), suggesting these factors may be coregulated. A cDNA microarray analysis for HGF-inducib...
Patients suffering from diabetes mellitus (DM) are at a severe risk of atherothrombosis. Early growth response (Egr)-1 is well characterized as a central mediator in vascular pathophysiology. We tested whether valsartan independent of Ang II type 1 receptor (AT1R) can reduce tissue factor (TF) and toll-like receptor (TLR)-2 and -4 by regulating Egr-1 in THP-1 cells and aorta in streptozotocin-i...
Early growth response (Egr)-1 is a transcription factor that regulates genes involved in inflammation, innate and adaptive immunity, coagulation, and wound healing; however, little is known about the role of Egr-1 in acute liver injury. We tested the hypothesis that Egr-1 is involved in acute liver injury induced by galactosamine/lipopolysaccharide (GalN/LPS). GalN/LPS exposure biphasically inc...
