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.
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 ...
Advancements in high-throughput technologies to measure increasingly complex biological phenomena at the genomic level are rapidly changing the face of biological research from single-gene single-protein experimental approach to studying the behaviour of a ...
Understanding host-microbe interactions has been greatly enhanced by our broadening knowledge of the regulatory mechanisms at the heart of pathogenesis. The "transcriptomics" approach of measuring global gene expression has identified genes involved in bac ...
Sequence-specific binding of a transcription factor to DNA is the central event in any transcriptional regulatory network. However, relatively little is known about the evolutionary plasticity of transcription factors. For example, the exact functional con ...
The thymus is the second fundamental organ of the immune system after the bone marrow; it is the essential for T cell maturation and repertoire selection. The function of the thymus critically depends on the thymic epithelium, which is structured in two di ...
BACKGROUND: Processing by gamma-secretase of many type-I membrane protein substrates triggers signaling cascades by releasing intracellular domains (ICDs) that, following nuclear translocation, modulate the transcription of different genes regulating a div ...
BACKGROUND: To understand cancer-related modifications to transcriptional programs requires detailed knowledge about the activation of signal-transduction pathways and gene expression programs. To investigate the mechanisms of target gene regulation by hum ...
Snail-type transcription factors (TFs) are found in numerous metazoan organisms and function in a plethora of cellular and developmental processes including mesoderm and neuronal development, apoptosis and cancer. So far, Snail-type TFs are exclusively kno ...
Collinear expression of 5′ Hoxd genes during mammalian limb development is required to properly determine digits number and identity. We recently proposed a two-step model to account for the underlying regulatory mechanism, which involves an initial loopin ...
Numerous methods have been developed for inferring gene regulatory networks from expression data, however, both their absolute and comparative performance remain poorly understood. In this paper, we introduce a framework for critical performance assessment ...
