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.
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 ...
Bile acids (BAs) are amphipathic molecules that facilitate the uptake of lipids, and their levels fluctuate in the intestines as well as in the circulation depending on food intake. Besides their role in dietary lipid absorption, BAs function as signaling ...
Notch signaling is among one of the highly conserved developmental pathways. Because of its role in the regulation of stem cell self-renewal and cell fate decisions, Notch signaling maintains tissue homeostasis in several organs such as thymus, skin and in ...
The Notch signalling pathway is an ancient cell signalling mechanism that enables short-range communications between cells and controls a broad spectrum of cell fates and developmental processes. In the haematopoietic system Notch signalling has been linke ...
The Notch signaling pathway is an ubiquitous cell-cell interaction mechanism, which is essential in controlling processes like cell proliferation, cell fate decision, differentiation or stem cell maintenance. Recent data have shown that Notch signaling is ...
Notch signaling is a conserved cell-to-cell communication pathway essential in the development and maintenance of various tissues. Upon ligand binding, Notch receptors on the cell surface are proteolytically cleaved, generating the intracellular domain of ...
In the pancreas, Notch signaling is thought to prevent cell differentiation, thereby maintaining progenitors in an undifferentiated state. Here, we show that Notch renders progenitors competent to differentiate into ductal and endocrine cells by inducing a ...
Steroid hormones coordinate and control the development and function of many organs and are implicated in many pathological processes. Progesterone signaling, in particular, is essential for several important female reproductive functions. Physiological ef ...
The Notch signaling cascade is a well conserved pathway that regulates many aspects of embryonic development and plays a crucial role in the differentiation process and tissue homeostasis in multiple organs of adult species. Several human pathological diso ...
BACKGROUND: The Ras and Notch signaling pathways are frequently activated during development to control many diverse cellular processes and are often dysregulated during tumorigenesis. To study the role of Notch and oncogenic Kras signaling in a progenitor ...
