Endothelial cells (ECs) subjected to shear stress constantly release nitric oxide (NO). The effect of NO on shear stress-induced endothelial responses was examined. ECs subjected to shear stress induced a transient and shear force-dependent increase in early growth response-1 (Egr-1) mRNA levels. Treatment of ECs with an NO donor, S-nitroso-N-acetylpenicillamine (SNAP) or 3-morpholinosydnonimin...
The Ca2+-induced expression of the primary response genes egr-1 and c-fos was investigated in the murine erythroleukaemia cell line ELM-I-1. Exposure of the cells to the Ca2+-ionophore A23187 led to a rapid transient rise in egr-1 and c-fos mRNA production followed by an increase in Egr-1 and c-Fos protein levels as well as an increase in Egr-1 and activator protein 1 (AP-1) DNA-binding activit...
Hepatocyte injury during cholestasis depends in part on the release of proinflammatory mediators that cause neutrophils to accumulate in the liver and become activated to damage hepatocytes. The mechanism by which cholestasis stimulates production of proinflammatory mediators in the liver is not completely understood. The studies presented here tested the hypothesis that the transcription facto...
Hepatocyte growth factor (HGF) receptor, the product of the c-met protooncogene, is transcriptionally regulated by a wide variety of cytokines as well as extracellular environmental cues. In this report, we demonstrate that c-met expression was significantly suppressed by oxidative stress. Treatment of mouse renal inner medullary collecting duct epithelial cells with 0.5 mM H(2)O(2) inhibited c...
The C(2)H(2) zinc-finger transcription factor Egr-1 has previously been shown to play an essential role within the endocrine system as a molecular determinant of LH beta-subunit synthesis in anterior pituitary gonadotrophs. The extent to which Egr-1 may be a dynamic mediator of changes in gonadotroph function during the oestrous cycle is currently unclear. We have recently produced a novel rat ...
The p21Waf1/Cip1 protein (hereafter, p21) and the c‑Jun N-terminal kinase (JNK) are two well-characterized cell modulators that play a crucial role in cell differentiation, senescence and apoptosis. Here, we report that transcription of the p21Waf1/Cip1 and JNK-1 genes is affected by inhibition of the early growth response-1 (Egr-1) in response to a small interfering RNA [siRNA)-Egr-1] in LNCaP...
Immediate-early gene expression is a key part of a neuron's response to behaviorally relevant stimuli and, as a result, localization of immediate-early gene expression can be a useful marker for neural activity. We characterized the immediate-early gene egr-1 (also called zif268, NGFI-A, krox-24, ZENK) in the teleost Astatotilapia (Haplochromis) burtoni. We compared the A. burtoni egr-1 predict...
This study investigated the effects of high exhaust gas recirculation (EGR) rates on dimethyl ether (DME) fuel combustion performance, exhaust emissions and particle emission characteristics in a small direct injection diesel engine under various injection timings. To examine the effect of EGR and injection timings, the experiment was performed under high EGR rates (0%, 30%, 50%) and injection ...
The early growth response-1 transcription factor (Egr-1) is induced as part of the immediate-early gene expression response during early liver regeneration. In the studies reported here the functional significance of EGR-1 expression during liver regeneration was examined by characterizing the hepatic regenerative response to partial hepatectomy in Egr-1 null mice. The results of these studies ...
BACKGROUND N-4-Tert-Butyl benzyl haloperidol chloride (C(3)) was a novel calcium antagonist synthesized in our laboratory. The present study is to explore the effect of C(3) on vascular smooth muscle cell proliferation and the mechanism involved. METHODS The effects of C(3) on Ang II-induced cytosolic free Ca(2+) concentration change, VSMC proliferation, the key early growth response factor 1...
