Abstract

fetched live from OpenAlex

Les cancers cutanés sont associés à la formation des dimères cyclobutyliques de pyrimidine (DCP) générés par les ultraviolets (UV) du soleil. Nos résultats indiquent que les transversions T-->G retrouvées suite aux UVA sont dues aux DCP formés majoritairement sur les TT. Nous avons également démontré que, contrairement au dogme établi, les protéines réparant les mésappariements n'influencent pas la réparation des DCP. p53 a indéniablement une influence sur la réparation des DCP. Cependant, la lignée SW480, contenant un gène p53 double-muté, est fonctionnelle en réparation par excision de nucléotides des DCP. Normalement, un stress est nécessaire à l'activation des effecteurs de p53. Cependant, la protéine p53 double-mutée des SW480 active constitutivement p21, un effecteur de p53. L'activation des protéines réparant les DCP par p53 se fait probablement de la même façon que p21. L'éclaircissement de ces mécanismes a amené une meilleure compréhension de l'induction des cancers.

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.
