Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Both beta-catenin and plakoglobin can stimulate the expression of Lef/Tcf target genes in vitro. beta-Catenin is known to associate with Lef/Tcf factors and to participate directly in transactivation in vivo, whereas the role of plakoglobin in transcriptio ...
Cell membrane receptors and ion channels are essential in many different cellular processes. To analyse the activity of membrane proteins in vesicles and biological cells, we fabricated micro- nanostructured chips, enabling the application of electrophysio ...
How membrane receptors transduce external signals across the membrane and activate intracellular processes is a key question for fundamental research and for therapeutic purposes. Reliable in situ investigations requiest to preserve the full biological act ...
Many central biol. signal transduction processes such as synaptic transmission occur at the level of cell membranes. It is therefore not surprising that the biol. function of membrane proteins in general and neuroreceptors in particular can be modulated by ...
Many mono or multicellular organisms secrete soluble proteins, referred to as protein toxins, which alter the behavior of foreign, or target cells, possibly leading to their death. These toxins affect either the cell membrane by forming pores or modifying ...
G protein-coupled receptors (GPCR) constitute by far the largest family of transmembrane cell-surface proteins involved in signal transduction and are the most important targets for the development of novel therapeutic compounds. Many processes mediated by ...
Gab1 is a multiadaptor protein that has been shown to be required for multiple processes in embryonic development and oncogenic transformation. Gab1 functions by amplifying signal transduction downstream of various receptor tyrosine kinases through recruit ...
Airway smooth muscle constriction leads to the development of compressive stress on bronchial epithelial cells. Normal human bronchial epithelial cells exposed to an apical-to-basal transcellular pressure difference equivalent to the computed stress in the ...
Targeted gene transfer into human cells has previously been achieved with spleen necrosis virus (SNV)-derived vector particles harboring envelope (Env) proteins which carry single chain Fv (scFv) domains derived from antibodies. Such cell targeting vectors ...
