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.
The septation initiation network (SIN) in Schizosaccharomyces pombe regulates cytokinesis. Cdc7p encodes the first kinase in the core SIN pathway. In this study, I performed a genetic screen to identify novel regulators of the SIN pathway by isolating spon ...
Aim and applications: 1. Optimize fluorescence-based cellular assays for getting insights about mechanisms leading to cell death 2. Informative high content assays development with the aim to implement them in order to obtain preliminary toxicity informati ...
Stem-like cells may be integral to the development and maintenance of human cancers. Direct proof is still lacking, mainly because of our poor understanding of the biological differences between normal and cancer stem cells (SCs). Using the ErbB2 transgeni ...
Non-replicating or dormant cells of Mycobacterium tuberculosis constitute a challenge to tuberculosis (TB) therapy because of their tolerance or phenotypic resistance to most drugs. Here, we propose a simple model for testing drugs against non-growing cell ...
The Schizosaccharomyces pombe septation initiation network regulates cytokinesis. Cdc7p is the first kinase in the core septation initiation network; we have screened genetically for SIN regulators by isolating cold-sensitive suppressors of cdc7-24. Our sc ...
Exposure of a bacterial culture to an antibiotic or other lethal stress typically results in the generation of sub-populations of live cells ("persisters") and dead cells, and, in some cases, viable but non-culturable cells. Studies aimed at understanding ...
Pathogens of bacterial and viral origin hijack pathways operating in eukaryotic cells in many ways in order to gain access into the host, to establish themselves and to eventually produce their progeny. The detailed molecular characterization of the subver ...
Synthetic biomaterials play an important role in regenerative medicine. To be effective they must support cell attachment and proliferation in addition to being non-toxic and non-immunogenic. We used a suspension-adapted Chinese hamster ovary-derived cell ...
Observations of real-time changes in living cells have contributed much to the field of cellular biology. The ability to image whole, living cells with nanometre resolution on a timescale that is relevant to dynamic cellular processes has so far been elusi ...
Phenotypic heterogeneity, defined as metastable variation in cellular parameters generated by epigenetic mechanisms, is crucial for the persistence of bacterial populations under fluctuating selective pressures. Diversity ensures that some individuals will ...
