Evaluation of Recombination Repair Pathways in Thermal Radiosensitization
Bibliographic record
Abstract
Thermal radiosensitization has been shown to cause inhibition of repair of sublethal and potentially lethal damage and DNA DSBs. In this study we assessed thermal radiosensitization in mutants deficient in homologous recombinational (HR) repair and nonhomologous end joining repair (NHEJ). Using cells of the mouse wild-type embryo fibroblast cell line MEF and its Ku80(-/-) derivative that is deficient in NHEJ, we showed that thermal radiosensitization is the same in both cell lines. Further studies with cells of the wild-type CHO-AA8 cell line and its derivative IRS(ISF), which is deficient in HR, also showed comparable thermal radiosensitization in both cell lines. Further experiments using cells of chicken DT40 cell lines also showed comparable thermal radiosensitization between the wild-type HR mutant Rad54, the NHEJ mutant Ku70, and the double mutant Rad 54-Ku70. These results indicate that the HR and NHEJ pathways may not be targets for thermal radiosensitization.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
