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.
During early somite stages of development, the broad endoderm-derived foregut and hindgut territories become further subdivided along the antero-posterior axis into organs. One of these organs is the pancreas which serves two major physiological functions: ...
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 ...
Planar cell polarity (PCP) refers to the collective orientation of cells within the epithelial plane. We show that progenitor cells forming the ducts of the embryonic pancreas express PCP proteins and exhibit an active PCP pathway. Planar polarity proteins ...

Pancreas development is initiated by the specification and expansion of a small group of endodermal cells. Several transcription factors are crucial for progenitor maintenance and expansion, but their interactions and the downstream targets mediating their ...

Pancreatic cancer is one of the most fatal malignancies lacking effective therapies. Notch signaling is a key regulator of cell fate specification and pancreatic cancer development; however, the role of individual Notch receptors and downstream signaling i ...
Cyclooxyganase-2 (COX-2), a rate-limiting enzyme in the prostaglandin synthesis pathway, is overexpressed in many cancers and contributes to cancer progression through tumor cell-autonomous and paracrine effects. Regular use of non-steroidal anti-inflammat ...

Preclinical trials in mice represent a critical step in the evaluation of experimental therapeutics. Genetically engineered mouse models (GEMMs) represent a promising platform for the evaluation of drugs, particularly those targeting the tumor microenviron ...
The pancreas plays a central role in metabolism. The exocrine pancreas, composed of ductal and acinar cells, secretes and delivers digestive enzymes into the duodenum where they contribute to food digestion. The endocrine pancreas, constituted by the islet ...
During development, pancreatic endocrine cells are specified within the pancreatic epithelium. They subsequently delaminate out of the epithelium and cluster in the mesenchyme to form the islets of Langerhans. Neurogenin3 (Ngn3) is a transcription factor r ...

The pancreas is one of the major organs of the digestive tract. Its endocrine function, mainly regulating glucose blood level, is achieved by endocrine cells. These cells are organized in clusters, the so-called islets of Langerhans. During development, th ...
