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.
We evaluated the metabolic impact of farnesoid X receptor (FXR) activation by administering a synthetic FXR agonist (GW4064) to mice in which obesity was induced by a high fat diet. Administration of GW4064 accentuated body weight gain and glucose intolera ...
The role of the tumor suppressor retinoblastoma protein (pRb) has been firmly established in the control of cell cycle, apoptosis, and differentiation. Recently, it was demonstrated that lack of pRb promotes a switch from white to brown adipocyte different ...
To investigate whether intracellular amyloid beta (iA beta) induces toxicity in wild type (WT) and APP/PS1 mice, a mouse model of Alzheimer's disease. ...
Cells respond to stress by coordinating proliferative and metabolic pathways. Starvation restricts cell proliferative (glycolytic) and activates energy productive (oxidative) pathways. Conversely, cell growth and proliferation require increased glycolytic ...
Embryonic motoneurons from mutant SOD1 (mSOD1) mouse models of amyotrophic lateral sclerosis (ALS), but not wild-type motoneurons, can be triggered to die by exposure to nitric oxide (NO), leading to activation of a motoneuron-specific signaling pathway do ...
raptor is a specific and essential component of mammalian TOR complex 1 (mTORC1), a key regulator of cell growth and metabolism. To investigate a role of adipose mTORC1 in regulation of adipose and whole-body metabolism, we generated mice with an adipose-s ...
The maintenance of metabolic homeostasis relies on the balanced intake of nutrients from food. Consequently, diet composition strongly impacts whole-body physiology. Dietary formulations with strong nutrient imbalances can lead to metabolic disorders, with ...
RNAi holds promise for neurodegenerative disorders caused by gain-of-function mutations. We and others have demonstrated proof-of-principle for viral-mediated RNAi in a mouse model of motor neuron disease. Lentivirus and adeno-associated virus have been us ...
The neurochemical profile of the striatum of R6/2 Huntington's disease mice was examined at different stages of pathogenesis using in vivo1H NMR spectroscopy at 9.4 T. Between 8 and 12 weeks, R6/2 mice exhibited distinct changes in a set of 17 quantifiable ...
Body mass and composition reflect the combined effects of three processes: energy intake, energy partitioning (storage), and energy expenditure. Energy is released from food as it is combusted to carbon dioxide and water, and is expended as heat and work w ...
