Abstract
Sanazole/DNA repair/Hypoxic radiosensitization/DNA polymerases/Saccharomyces cerevisiae Yeast Saccharomyces cerevisiae can exist in two physiological states, namely anaerobic and aerobic. They differ in their response to gamma- radiation and radiomodification. We report hereon our results concerning radiosensitization by Sanazole (AK-2123), a well-known hypoxic radio sensitizer, whose mechanism of action has been studied extensively. The results have revealed that Sanazole (1 mM) when present during irradiation could specifically sensitize wild-type anaerobic yeast cells with a DMF of 2.4. In a radiation-sensitive mutant which lacks a DNA repair pathway specific for the recovery from gamma-radiation induced DNA damage, the extent of sensitization was considerably lower and the DMF was only 1.3. Studies on the liquid holding recovery of cells of both wild- type and rad52 yeast cells exposed to radiation in presence of Sanazole revealed that sensitization by Sanazole is due to a preferential increase in the DNA damage, and not by impairing DNA repair. This system thus holds promise for screening potential hypoxic chemical radiosensitizers.

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 it
