Kaposi's sarcoma associated herpesvirus (KSHV) regulates the host cellular environment to establish life-long persistent infection by manipulating cellular signaling pathways, with approximately 1- 5% of cells undergoing lytic reactivation during the course of infection. Egr-1 (Early Growth Response Factor-1) is one such cellular transcription factor, which gets phosphorylated during the lytic ...

Treatment of quiescent primary human fibroblasts with tumor necrosis factor (TNF) alpha, TNF-beta, interleukin-1, interferon (IFN) alpha, IFN beta, or IFN gamma induced Egr-1 mRNA. In primary human fibroblasts TNF-alpha and TNF-beta were mildly mitogenic and IFN alpha and IFN gamma were growth inhibitory. However, in HeLa cells TNF but not IFN induced the expression of Egr-1 mRNA, while both cy...

Early Growth response-1 (Egr-1) is a transcription factor that possesses a variety of biological functions. It has been shown to regulate HSV-1 gene expression and replication in different cellular environments through the recruitment of distinct cofactor complexes. Previous studies demonstrated that Egr-1 can be induced by HSV-1 infection in corneal cells but the level was lower compared to ot...

Early growth response factor-1 (Egr-1) controls the expression of a growing number of genes involved in the pathogenesis of atherosclerosis and postangioplasty restenosis. Egr-1 is activated by diverse proatherogenic stimuli. As such, this transcription factor represents a key molecular target in efforts to control vascular lesion formation in humans. In this study, we have generated DNAzymes t...

in the diesel engine exhaust gas recirculation (egr) components, valve and connecting pipes are the critical components and fails often during new engine development. these components are important for meeting nox emissions norms. therefore design of these components should remain robust. but the challenge in design is compact packaging of complete egr components on the engine consequently vibr...

in this study a heat exchanger is designed for cooling exhaust gas and an experiment is carried out to investigate the effect of exhaust gas recirculation (egr) temperature on destruction of the fuel’s availability due to combustion processes in idi diesel engine cylinder. to serve this aim an exergy analysis is conducted on the engine cylinder which provides all the availability terms by which...

Aging is associated with a large number of both phenotypic and molecular changes, but for most of these, it is not known whether these changes are detrimental, neutral, or protective. We have identified a conserved Caenorhabditis elegans GATA transcription factor/MTA-1 homolog egr-1 (lin-40) that extends lifespan and promotes resistance to heat and UV stress when overexpressed. Expression of eg...
