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.
Adeno-associated virus type 2 (AAV2) provokes a DNA damage response that mimics a stalled replication fork. We have previously shown that this response is dependent on ataxia telangiectasia-mutated and Rad3- related kinase and involves recruitment of DNA r ...
Human papillomavirus (HPV) begins its life cycle by infecting the basal cells of the epithelium. Within these proliferating cells, the viral genomes are replicated, maintained, and passed on to the daughter cells. Using HPV episome-containing cell lines th ...
Adeno-associated virus type 2 (AAV2) infection incites cells to arrest with 4N DNA content or die if the p53 pathway is defective. This arrest depends on AAV2 DNA, which is single stranded with inverted terminal repeats that serve as primers during viral D ...
BACKGROUND: Phi29 polymerase based amplification methods provides amplified DNA with minimal changes in sequence and relative abundance for many biomedical applications. RNA virus detection using microarrays, however, can present a challenge because phi29 ...
A synthetic antibody phage library, (ETH-2) was screened against the MUC-1 peptide. Two standard methods were used, namely screening on immunotubes coated with the peptide antigen and on streptavidin-coated paramagnetic particles together with a biotinylat ...
TRIM5alpha is a restriction factor that limits infection of human cells by so-called N- but not B- or NB-tropic strains of murine leukemia virus (MLV). Here, we performed a mutation-based functional analysis of TRIM5alpha-mediated MLV restriction. Our resu ...
Forkhead/winged-helix transcription factors are evolutionarily conserved and found in organisms as diverse as yeast and humans. They regulate a broad spectrum of events during embryonic and post natal development, including cell cycle regulation, survival, ...
The human papillomavirus (HPV) E1 empty set E4 protein is the most abundantly expressed viral protein in HPV-infected epithelia. It possesses diverse activities, including the ability to bind to the cytokeratin network and to DEAD-box proteins, and in some ...
The presence of a 174 kb plasmid called pMUM001 in Mycobacterium ulcerans, the first example of a mycobacterial plasmid encoding a virulence determinant, was recently reported. Over half of pMUM001 is devoted to six genes, three of which encode giant polyk ...
Integration of a DNA copy of the viral RNA genome is a crucial step in the life cycle of human immunodeficiency virus type 1 (HIV-1) and other retroviruses. While the virally encoded integrase is key to this process, cellular factors yet to be characterize ...
