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.
Bio-inspiration borrows three properties characteristic of living organisms: multicellular architecture, cellular division, and cellular differentiation. Implemented in silicon according to these properties, our self-organizing systems are able to grow, to ...
Adeno-associated virus (AAV) type 2 or UV-inactivated AAV (UV-AAV2) infection provokes a DNA damage response that leads to cell cycle arrest at the G2/M border. p53-deficient cells cannot sustain the G2 arrest, enter prolonged impaired mitosis, and die. He ...
Adeno-associated virus (AAV) DNA, by mimicking a stalled replication fork, provokes a DNA damage response that can arrest cells in the G2/M phase of the cell-cycle. This response depends strictly on DNA damage signaling kinases ATR and Chk1. Here, we used ...

Cytokinesis is the final stage of the cell cycle, and ensures completion of both genome segregation and organelle distribution to the daughter cells. Cytokinesis requires the cell to solve a spatial problem (to divide in the correct place, orthogonally to ...
The human KIN17 protein is an essential nuclear protein conserved from yeast to human and expressed ubiquitously in mammals. Suppression of Rts2, the yeast equivalent of gene KIN17, renders the cells unviable, and silencing the human KIN17 gene slows cell ...
New trans-platinum planar amines (TPAs) represent a family of platinum-based drugs with cytotoxicity equivalent to that of cisplatin, but with negligible cross-resistance. According to the substitution pattern around the metal center, distinct DNA adducts ...
Poly(ADP-ribosyl) polymerases (PARPs) have traditionally been linked to chromosome maintenance and DNA repair. Recent findings identify PARPs as key modulators of metabolism through their influence on SIRT1 activity, hinting to a possible role of PARPs as ...
In a recent issue of Molecular Cell, Bonetti et al. (2009) identify in the yeast Saccharomyces cerevisiae that the molecular activities that generate 3' overhangs at telomeric DNA ends are the same as those that resect DNA at double-strand breaks. ...
DNA photolyase is a highly efficient light-driven enzyme that repairs the UV-induced cyclobutane pyrimidine dimer in damaged DNA. Herein, we investigate the repair reaction of the thymine dimer by means of hybrid quantum mechanical/molecular mechanical QM/ ...
