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.
Stem cell use in bladder tissue engineering is a recently addressed area of investigation that has generated excitement as a novel way to restore and regenerate lost or damaged urinary bladder tissue. The remodelling of smooth muscle plays a significant ro ...
Muscular arteries possess the ability to control actively their lumen by altering the tone of the smooth muscle cells of the arterial wall, a property which is vital for a large number of the hemodynamical functions of the body. Arterial contraction is due ...
The gene uncx4.1 is a paired-type homeobox transcription factor, expressed during zebrafish embryonic development in branchial arches, somites, CNS and pronephric ducts. In particular, the expression at the somite level is detectable from 5ss stage and bec ...
Stretch-elicited intracellular calcium (Ca(2+)) changes in individual smooth muscle cells in a ring of aorta were measured simultaneously with the force developed by the ring. A phasic increase in Ca(2+) was observed in 30% of the cells and a sus ...
Asynchronous and synchronous calcium oscillations occur in a variety of cells. A well-established pathway for intercellular communication is provided by gap junctions which connect adjacent cells and can mediate electrical and chemical coupling. Several ex ...
Fas-induced death of motoneurons in vitro has been shown to involve two signaling cascades that act together to execute the death program: a Fas-Daxx-ASK-1-p38 kinase-nNOS branch, which controls transcriptional and post-translational events, and the second ...
Investigating the recruitment and synchronization of smooth muscle cells (SMCs) is the key to understanding the physical mechanisms leading to contraction and spontaneous diameter oscillations of arteries, called vasomotion. We improved a method that allow ...
Based on our previous results, we investigated whether cyclosporin A (CsA)-induced vasopressin type 1A receptor up-regulation was mediated by free radicals. We report that CsA analogues with different affinities for cyclophilin and calcineurin were able to ...
An endothelial cell monolayer with a single mechanically lysed cell was used as a model to examine the extent, kinetics, and nature of local calcium mobilization in the neighborhood of a wound. Individual endothelial cells from confluent monolayers were me ...
Human papillomaviruses (HPV) replicate in keratinocyte but not fibroblast cells. Several factors, including AP1 (Jun/Fos), contribute to the cell-type specific transcription of HPV genes. The binding of AP1 upstream of the HPV type 18 early gene E6 is esse ...
