The nongenomic effects of aldosterone have been implicated in the pathogenesis of various cardiovascular diseases. Aldosterone-induced nongenomic effects are attributable in part to the activation of extracellular signal-regulated kinase 1/2 (ERK1/2), a classical mitogen-activated protein (MAP) kinase. Big MAP kinase 1 (BMK1), a newly identified MAP kinase, has been shown to be involved in cell...

Abstract Salient object detection via deep neural networks usually needs a large amount of images with human annotation. To avoid laborious and consuming annotation, we propose robust unsupervised salient method three stages in this work. Our first uses unlabeled data to generate an activation map which indicates the coarse location object. Then one scribble generation based on is proposed, pro...

How should Location Based Services (LBS) look like? What should they offer and in which form? This paper aims at answering some of these kinds of questions by presenting the results of a detailed survey recently undertaken in Heidelberg, Germany. A general section covers questions about the acceptance of different content types and services on mobile devices. Furthermore the preferences of vari...

Chromium is an important industrial metal, an environmental pollutant, and a human carcinogen. To investigate the mechanisms of chromium-induced carcinogenesis, activation of mitogen-activated protein (MAP) kinases ERK1 and ERK2 was examined in rat hepatoma cells following exposure to hexavalent chromium (Cr(VI)). Cr(VI) was found to activate both forms of MAP kinase in a dose- and time-depende...

In many tumor cells, the activation and activity of extracellular signal-regulated kinases (ERK1/2) are very high because of the constitutive activation of the Ras-mediated signaling pathway. Here, we ectopically expressed the human homologue of rat eukaryotic initiation factor 2-associated glycoprotein, p67/MetAP2, in EGF-treated mouse embryonic NIH3T3 fibroblasts and C2C12 myoblasts and NIH3T...

A variety of extracellular signals lead to the phosphorylation and activation of mitogen-activated protein kinases (MAP kinases). An activator of MAP kinases, Mek1, phosphorylates MAP kinases at threonine and tyrosine residues and is itself phosphorylated at serine-218 and -222 by the protooncogene product Raf-1. By introducing negatively charged residues that may mimic the effect of phosphoryl...

The phosphorylation of transcription factors by mitogen-activated protein kinases (MAP) is a pivotal event in the cellular response to the activation of MAP kinase signal transduction pathways. Mitogenic and stress stimuli activate different pathways and lead to the activation of distinct groups of target proteins. Elk-1 is targeted by three distinct MAP kinase pathways. In this study, we demon...
