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.
In fission yeast, the onset of septation is signalled through the septum initiation network (SIN) signaling pathway. Similarly, in budding yeast the onset of budding is signalled through the mitotic exit network (MEN) pathway. We previously characterized i ...

Cell cultures from reef-building scleractinian corals are being developed to study the response of these ecologically important organisms to environmental stress and diseases. Despite the importance of cell division to support propagation, cell proliferati ...
Since stem cells have the unique ability to produce more of themselves (i.e. to "self-renew") and to generate specialized tissue cells, they are an ideal source of cells for regenerative medicine and in vitro tissue models. In order to fully exploit this p ...
The mammalian intestine has one of the highest turnover rates in the body. The intestinal epithelium is completely renewed in less than a week. It is divided into spatially distinct compartments in the form of finger-like projections and invaginations that ...
In this issue of Developmental Cell, Sakano et al. describe a novel mechanism of how a key lymphocyte transcription factor crosstalks to Notch signaling during embryonic development and thereby selectively inhibits Notch-activated target genes to allow pro ...

Transgenic animals are essential research tools, whether to address basic biological questions or to develop preclinical models of human diseases. Their generation through the injection of naked plasmid DNA into the male pronucleus of a fertilized oocyte h ...

One of the basic characteristics of every living system is the ability to respond to extracellular signals. This is carried out through a limited number of protein-based signaling networks, whose function is not based only on simple transmission of the rec ...

PIKfyve is a kinase encoded by pip5k3 involved in phosphatidylinositols (PdtIns) pathways. These lipids building cell membranes have structural functions and are involved in complex intracellular regulations. Mutations in human PIP5K3 are associated with F ...
The Cajal body (CB) is an evolutionarily conserved nuclear subcompartment, enriched in components of the RNA processing machinery. The composition and dynamics of CBs in cells of living organisms is not well understood. Here we establish the zebrafish embr ...
Centrosomes are the principal microtubule organizing centers (MTOCs) of animal cells and comprise a pair of centrioles surrounded by pericentriolar material (PCM). Centriole number must be carefully regulated, notably to ensure bipolar spindle formation an ...
