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.
Gene expression profiling of beta-catenin, Cripto and Wnt3 mutant mouse embryos has been used to characterise the genetic networks that regulate early embryonic development. We have defined genes whose expression is regulated by beta-catenin during formati ...
Ewing's sarcoma is a member of Ewing's family tumors (EFTs) and the second most common solid bone and soft tissue malignancy of children and young adults. It is associated in 85% of cases with the t(11;22)(q24:q12) chromosomal translocation that generates ...
The aim of this thesis is to optimise and gain fundamental information on two applications of photomedicine using fluorescence imaging and spectrofluorometry: (1) the detection of early bronchial cancer by autofluorescence imaging and (2) the endometrial a ...
Telomerase is crucial for human carcinogenesis. The limiting component of telomerase activity is telomerase reverse transcriptase (hTERT), undetectable in differentiated somatic cells but present in most tumor cells. There is evidence that hTERT transcript ...
The DNA repair protein O6-methylguanine-DNA methyltransferase (MGMT, alkyltransferase) is an important suicide enzyme involved in defense against O6-alkylating endogenous metabolites and environmental carcinogens. It also plays a pivotal role in primary an ...
For better understanding of genetic mechanisms underlying clinical observations, it is interesting to determine which genes and clinical traits are interrelated. In the last few years a consistent amount of research in genomics has been done concerning cor ...
We have previously reported that IGF-II binds the extracellular matrix protein vitronectin (VN) with an affinity similar to that for the type-1 IGF receptor (IGF-1R). In view of this finding, and given the cited role of VN in cell motility and adhesion, we ...
A series of trans-platinum(IV) complexes with functionalized aromatic carboxylate ligands, cis,cis,trans-Pt(NH3)2Cl2(CO2C6H4R)2 (R = H (3), p-vinyl (4), p-methoxy (5), p-iodo (6), ...
The early detection and localization of bronchial cancer remains a challenging task. Autofluorescence bronchoscopy is emerging as a useful diagnostic tool with improved sensitivity and specificity. Evidence exists that the native fluorescence or autofluore ...
Notch proteins are important in binary cell-fate decisions and inhibiting differentiation in many developmental systems, and aberrant Notch signaling is associated with tumorigenesis. The role of Notch signaling in mammalian skin is less well characterized ...
