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...

Cooled exhaust gas recirculation (EGR) is a very effective method to reduce nitrogen oxide emissions of diesel engines. However, due to particulate matter and other components present in diesel exhaust gas, EGR coolers are highly prone to fouling. As different soot deposition mechanisms are acting inside the coolers, various model cooler experiments were performed to clarify their contribution ...

TCR engagement leads to the up-regulation of genetic programs that can both activate and inhibit T cell function. The early growth receptor (Egr) proteins Egr-2 and Egr-3 have recently been identified as TCR-induced negative regulators of T cell function. NAB2 (NGFI-A-binding protein 2) is both a coactivator and a corepressor of Egr-mediated transcription and has been implicated in regulating S...

This study explored the effects of propofol on c-Fos and Egr-1 in neuroblastoma (N2A) cells. We demonstrate that propofol induced the expression of c-Fos and Egr-1 within 30 and 60 min of exposure time. At 16.8 microM concentration, propofol induced a 6 and 2.5-fold expression of c-Fos and Egr-1, respectively. However, at concentrations above 100 microM, propofol failed to induce expression of ...

Hypoxic induction of the early growth response-1 (Egr-1) transcription factor initiates proinflammatory and procoagulant gene expression. Orthotopic/isogeneic rat lung transplantation triggers Egr-1 expression and nuclear DNA binding activity corresponding to Egr-1, which leads to increased expression of downstream target genes such as interleukin-1β, tissue factor, and plasminogen activator in...

The zinc finger transcription factor Egr-1 is critical for coupling extracellular signals to changes in cellular gene expression. In the hippocampus and amygdala, two major central regions for memory formation and storage, Egr-1 is up-regulated by long-term potentiation (LTP) and learning paradigms. Using Egr-1 knockout mice, we showed that Egr-1 was selectively required for late auditory fear ...

Gasoline compression ignition (GCI) has been shown as one of the advanced combustion concepts that could potentially provide a pathway to achieve cleaner and more efficient combustion engines. Fuel and air in GCI are not fully premixed compared to homogeneous charge compression ignition (HCCI), which is a completely kinetic-controlled combustion system. Therefore, the combustion phasing can be ...

Early growth response-1 (Egr-1) is involved in the regulation of cell growth. Here, we found that overexpression of phospholipase D (PLD) isozymes decreased tumor promoter phorbol myristate acetate (PMA)-induced Egr-1 expression and transactivation in glioma cells. Suppression of PMA-induced Egr-1 was dependent on the expression level of PLD isozymes. Overexpression of catalytically inactive PL...

Abstract This work evaluated the effect of cooled exhaust gas recirculation (EGR) on fuel consumption and pollutant emissions from a diesel engine fueled with B8 (a blend biodiesel no. 8:92% by volume), experimentally numerically. Experiments were carried out power generator varying loads 5 kW to 35 10% cold EGR ratio. Exhaust (e.g., total hydrocarbons (THCs), nitrogen oxides (NOx), carbon mono...
