Low-activity allele of copper-zinc superoxide dismutase (CuZnSOD) in<i>Drosophila</i>increases paraquat genotoxicity but does not affect near UV radiation damage
Bibliographic record
Abstract
Different types of mutations and DNA-damage profiles induced by near-UV radiation and the superoxide anion (O2-.) indicate separate lesions and (or) mechanisms of mutagenesis. Despite a wealth of data, it is still unclear whether variations in the activity levels of antioxidant enzymes naturally present in suboptimal concentrations are among the underlying causes of the increase of near UV radiation genotoxicity. We incorporated a low-activity allele of copper-zinc superoxide dismutase (CuZnSOD), recovered from natural populations of Drosophila melanogaster, into standard marked strains and employed a somatic mutation and recombination test (SMART) to compare paraquat and near UV radiation genotoxicity in these strains. Our results show that, although the low-activity CuZnSOD allele of D. melanogaster confers hypersensitivity to paraquat, the near UV radiation damage was not affected.

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.
