The aim of the present work was to analyze ... work was to analyze whether resistance to TGF-beta-induced apoptosis in HCC cells is related to the impairment of NOX4 up-regulation due to overactivation of survival signals. ...
2009 NOV 16 ... of the activation markers Fos in the spinal trigeminal nucleus and phosphorylated extracellularsignal-regulated kinase in the trigeminal ganglion. Pre-treatment with olcegepant (900 ... New investigation results, 'Calcitonin gene-related peptide receptor antagonist olcegepant acts in the spinal trigeminal nucleus,' are ...
2009 NOV 23 ... response to insulin attenuated whereas basal and insulin-stimulated phosphorylation of extracellularsignal-relatedkinase (ERK)1/2 was increased in type 2 diabetes MVEC. Endothelin (ET)-1 ...
2009 NOV 23 ... "Aims/hypothesis Extracellular pre-B cell colony-enhancing factor/nicotinamide phosphoribosyltransferase/visfatin ... smooth muscle cells, as well as the mechanisms involved. iNOS levels and extracellular signal-regulated kinase (ERK) 1/2 activity were determined by western blotting. Nuclear factor ... ability of ePBEF/NAMPT/visfatin to promote vascular inflammation, as a condition closely related to atherothrombotic diseases," researchers in Madrid, Spain report. "We ...
2009 NOV 23 ... in LP islets compared to NP islets (P < 0.05). Finally, the ratio of phosphorylated-extracellularsignal-relatedkinase 1/2 (pErk1/2) to total Erk1/2 protein levels was decreased by 71% ...
2009 NOV 3 ... and IFN-beta by plasmacytoid DCs was decreased in the absence of TPL-2, although extracellularsignal-regulated kinase (ERK) activation was blocked," wrote F. Kaiser and colleagues. ... F. Kaiser and colleagues. The researchers concluded: "Extracellular signal-related kinase-dependent negative regulation of IFN-beta in macrophages was IL-10-independent, ...
2009 NOV 23 ... by its ability to render Caco-2 cells tumorigenic in vivo all be it through selective extracellularsignal-relatedkinase (ERK) 2 phosphorylation and high levels of cyclin D1. As a ...
2009 NOV 1 ... was correlated with basal EGFR phosphorylation and inversely correlated with EGF-induced extracellularsignal-regulated protein kinase phosphorylation levels. Investigation of the NCI-60 cell ... expression dynamics. The results show the particular enrichment of EGFR/ErbB signaling-related genes in a differentially expressed gene set, and significant protein expression of ...
2009 NOV 16 ... (FGFR substrate 2 alpha), phospholipase C gamma, endothelial nitric oxide synthase, extracellularsignal-regulated kinase 1/2, and the transcription factor STAT-3. Synergism between PGE2 ... and Matrigel assays. The magnitude of the angiogenic response to PGE2 was directly related to FGF-2 availability which determined the extent of FGFR1 activation. In fact, PGE2 ...

2009 NOV 9 ... to investigate the differences in expression levels and distributions of phosphorylated extracellularsignal-regulated kinase (ERK)1/2, phosphorylated p38 MAPK and NF-kappa B p105/p50 in ... skin diseases." "The mechanism of long-lasting inflammatory processes is related with the activation of nuclear factor (NF)-kappa B and mitogen-activated protein kinase ...
2009 NOV 16 ... HO-1 reporter gene activity was diminished. Lansoprazole promoted the phosphorylation of extracellularsignal-regulated kinase (ERK), and lansoprazole-induced HO-1 up-regulation was ... largely unresolved. In this study, we investigate the role of transcriptional NF-E2-related factor 2 (Nrf2), its phosphorylation/activation, and oxidation of Kelch-like ...
2009 NOV 9 ... an important role in several types of pain. However, the detailed role of phosphorylated extracellularsignal-regulated kinase (pERK) in the region of injured peripheral nerve is poorly ... The researchers concluded: "Our results suggest that pERK itself and ERK-related mediators are potential therapeutic targets for the treatment of neuropathic pain. ...
2009 NOV 23 ... VSMC with LY333531 prevented high glucose-induced activation of nuclear factor kappa B, extracellularsignal-relatedkinase, and iNOS overexpression. Suppression of PKC beta(2) expression by ...
