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.
Huntington's disease (HD) is a progressive neurodegenerative disorder with autosomal dominant inheritance. It is caused by a singular mutation in exon 1 of the HD gene encoding an abnormal polyglutamine (polyQ) expansion in the N-terminal region of the hun ...
53BP1, the vertebrate ortholog of the budding yeast Rad9 and fission yeast Crb2/Rhp9 checkpoint proteins, is recruited rapidly to sites of DNA double-strand breaks (DSBs). A tandem tudor domain in human 53BP1 that recognizes methylated residues in the hist ...
The inhibitors of growth (ING) family of tumor suppressors consists of five homologous proteins involved in chromatin remodeling. They form part of different acetylation and deacetylation complexes and are thought to direct them to specific regions of the ...

Sirtuins (Sirts) compose a family of NAD(+)-dependent deacetylases and/or ADP-ribosyltransferases, which have been implicated in aging, metabolism, and tolerance to oxidative stress. Many of the biological processes regulated by Sirts result from the adapt ...
Being in the layer at the interface of the body with the outside world, keratinocyte stem cells constantly adapt and respond to environmental cues such as temperature and oxygen. However, until now, experiments involving temperature have only examined cold ...
Histone acetyl transferases (HATs) play a crucial role in eukaryotes by regulating chromatin architecture and locus-specific transcription. The GCN5 HAT was identified as a subunit of the SAGA (Spt-Ada-Gcn5-Acetyltransferase) multiprotein complex. Vertebra ...
A review. Histone deacetylase inhibitors are an emerging class of antiproliferative agents that have the potential to combat cancer on an epigenetic level. The recently reported marine natural product largazole was recently isolated in trace amts. from cya ...
KAP1 is an essential cofactor of KRAB-zinc finger proteins, a family of vertebrate-specific epigenetic repressors of largely unknown functions encoded in the hundreds by the mouse and human genomes. Here, we report that KAP1 is expressed at high levels and ...
The activity of locus control regions (LCR) has been correlated with chromatin decondensation, spreading of active chromatin marks, locus repositioning away from its chromosome territory (CT), increased association with transcription factories, and long-ra ...
One of the central questions in eukaryotic transcription is how activators can transmit their signal to stimulate gene expression in the context of chromatin. The multisubunit SAGA coactivator complex has both histone acetyltransferase and deubiquitination ...
