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.
Cellular homeostasis is maintained by tightly regulated gene networks, controlled notably at the levels of transcription, mRNA processing, and protein post-translational modification and turnover. This thesis focuses on two of these regulatory steps, namel ...
Mechanisms responsible for energy management in the cell and in the whole organism require a complex network of transcription factors and cofactors. Peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) has emerged as a master regulator of m ...

Objective Plaque-prone areas are exposed to a particular hemodynamic environment characterized by a low mean shear stress value and a cyclic reversal flow. This mechanical environment, also termed oscillatory shear stress (OSS), induces the expression of s ...
An emerging model views gene regulation as a competition for regulatory sequences between transcription factors and nucleosomes at thermodynamic equilibrium. A computational model of the DNA affinity of nucleosomes was recently developed allowing to predic ...
A new method was developed for the specific and covalent labeling of fusion proteins with small organic probes in vitro and in vivo. The method is based on the construction of fusion proteins of the human O6-alkylguanine-DNA alkyltransferase (hAGT) with a ...

Hormone binding nuclear receptors are transcription factors that activate gene transcription by binding to specific DNA sequences in the gene promoter region and then recruiting the necessary coactivator proteins for transcriptional activation. The knowled ...

The transcripts of many genes involved in Saccharomyces cerevisiae mating were found to fluctuate during the cell cycle. In the absence of a functional Ste12 transcription factor, both the levels and the cell cycle pattern of expression of these genes were ...
Fibrates have been reported to modulate plasma high density lipoprotein cholesterol and apolipoprotein (apo) A-I concentrations. Therefore, the molecular mechanisms underlying the regulation of human apoA-I gene expression by fibrates was investigated. Fen ...
During the course of lytic infection by simian virus 40 (SV40), expression of both the viral late genes and certain host cellular genes is induced. The promoter of the cellular transferrin receptor (TR) gene contains a DNA sequence which is similar to the ...
