Chattez avec Graph Search
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.
Heritable changes to the transcriptome that are independent to changes in the genome are defined as epigenetics. DNA methylation and posttranslational modifications of histones, such as acetylation/deacetylation and methylation/demethylation of lysine resi ...
Cellular homeostasis is maintained by tightly regulated gene networks, controlled notably at the levels of transcription, mRNA processing, and protein post-translational modification and turnover. This thesis focuses on two of these regulatory steps, namel ...
In this study, we present a detailed characterization of the full α/β interface in the farnesyltransferase (FTase) enzyme, an important target in drug design efforts. This characterization is presented in terms of hot spots, warm spots, and null spots and ...
The causes of sporadic Alzheimer's Disease (AD), the most common form of dementia at old age, are still unknown. Familial early onset AD (FAD) is mainly caused by mutations of Presenilins (PS), the active subunits of γ-secretase. Processing of its substrat ...
The HIV-1 Rev protein is responsible for shuttling partially spliced and unspliced viral mRNA out of the nucleus. This is a crucial step in the HIV-1 lifecycle, thus making Rev an attractive target for the design of anti-HIV drugs. Despite its importance, ...
Glycodendrimers, such as glycoclusters and glycopolymers, are known to be very useful molecules to probe carbohydrate-lectin interactions. Herein, new second generation glycopeptide dendrimers (G2a-f) presenting a L-lysin-based (Lys) tetraantennary scaffol ...
Transcription factor-DNA interactions are life sustaining and therefore the subject of intensive research. In spite of vast effort, quantitative in vivo studies of the molecular mechanisms underlying these fundamental interactions remain challenging. In th ...
Flagellar motility is an important process for bacterial survival. It allows bacteria to move to aquire nutrients or to retreat from unfavorable environments. In the Gram-positive bacterium Listeria monocytogenes, flagellar motility is a temperature-depend ...
Desulfitobacterium is a Gram-positive obligate anaerobic bacterium affiliated to the Firmicutes with a highly versatile carbon and energy metabolism. Increasing interest in this genus came with its involvement in the degradation of chlorinated compounds us ...
Summary Tuberculosis is still a leading cause of death in developing countries, for which there is an urgent need for new pharmacological agents. The synthesis of the novel antimycobacterial drug class of benzothiazinones (BTZs) and the identification of t ...
