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.
There are two main routes for tumor spread and metastasis, the blood vasculature and the lymphatic system. A wide range of human carcinomas, including lung, colon and breast cancer, spread to distant sites via the lymphatic system. Preclinical and clinical ...
Wnt signaling is essential for embryogenesis and adult tissue homeostasis and contributes to cancer development, especially in the colon. A new essential pathway component, legless, was identified in Drosophila melanogaster. Mice with Cre/loxP-mediated con ...
Tumor microenvironment contributes strongly to tumor evolution toward metastasis, a final stage in cancer progression. It provides essential clues to promote migration of cancer cells in metastatic sites. Moreover, inflammatory cells and immunomodulatory m ...
Cancer is a disease subject to both genetic and environmental influences. In this study, we used the RIP1-Tag2 (RT2) mouse model of islet cell carcinogenesis to identify a genetic locus that influences tumor progression to an invasive growth state. RT2 mic ...
Tumor-infiltrating myeloid cells, including tumor-associated macrophages (TAMs), have been implicated in tumor progression. We recently described a lineage of mouse monocytes characterized by expression of the Tie2 angiopoietin receptor and required for th ...
Metastasis is a multistep process that represents the final stage in cancer progression and heralds a terminal disease state. Understanding the molecular changes required for the establishment of metastases that are common or specific to a particular locat ...
Despite their apparent success in pre-clinical trials, metalloproteinase (MMP) inhibitors proved to be inefficacious in clinical settings. In an effort to understand the underlying causes of this unanticipated outcome, we modeled the consequences of long-t ...
Plasminogen activator inhibitor-1 is known to play a paradoxical positive role in tumor angiogenesis, but its contribution to metastatic spread remains unclear. We studied the impact of PAI-1 deficiency in a transgenic mouse model of ocular tumors originat ...
The therapeutic index of drugs that target DNA, a ubiquitous target present in nearly all cells, is low. Nevertheless, DNA has remained the primary target for medicinal chemists developing metal-based anticancer drugs, although DNA has been essentially aba ...
The modulation of the metastatic progression of breast cancer has been evaluated in vitro and in vivo with RAPTA-T, [Ru(η6-toluene)Cl2(PTA)], an organometallic ruthenium compd. In vitro RAPTA-T inhibits some steps of the metastatic process such as the deta ...
