Abstract

fetched live from OpenAlex

L'ADN de chaque cellule est constamment soumis à des stress pouvant compromettre son intégrité. Les bris double-brins sont probablement les dommages les plus nocifs pour la cellule et peuvent être des sources de réarrangements chromosomiques majeurs et mener au cancer s’ils sont mal réparés. La recombinaison homologue et la jonction d’extrémités non-homologues (JENH) sont deux voies fondamentalement différentes utilisées pour réparer ce type de dommage. Or, les mécanismes régulant le choix entre ces deux voies pour la réparation des bris double-brins demeurent nébuleux. Le complexe Mre11-Rad50-Xrs2 (MRX) est le premier acteur à être recruté à ce type de bris où il contribue à la réparation par recombinaison homologue ou JENH. À l’intersection de ces deux voies, il est donc idéalement placé pour orienter le choix de réparation. Ce mémoire met en lumière deux systèmes distincts de phosphorylation du complexe MRX régulant spécifiquement le JENH. L’un dépend de la progression du cycle cellulaire et inhibe le JENH, tandis que l’autre requiert la présence de dommages à l’ADN et est nécessaire au JENH. Ensembles, nos résultats suggèrent que le complexe MRX intègre différents phospho-stimuli pour réguler le choix de la voie de réparation.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
