Radiation-Induced Lung Response of AcB/BcA Recombinant Congenic Mice
Bibliographic record
Abstract
The genetic factors that influence the development of radiotherapy-induced lung disease are largely unknown. Herein we identified a strain difference in lung response to radiation wherein A/J mice developed alveolitis with increased levels of pulmonary mast cells and cells in bronchoalveolar lavage while the phenotype in C57BL/6J mice was fibrosis with fewer inflammatory cells. To identify genomic loci that may influence these phenotypes, we assessed recombinant congenic (RC) mice derived from the A/J and C57BL/6J strains for their propensity to develop alveolitis or fibrosis after 18 Gy whole-thorax irradiation. Mouse survival, lung histopathology and bronchoalveolar lavage cell types were recorded. Informative strains for each of mast cell influx, bronchoalveolar cell numbers, alveolitis and fibrosis were identified. In mice with the A/J strain background, the severity of alveolitis correlated with increased mast cell numbers while in C57BL/6J background strain mice fibrosis was correlated with the percentage of neutrophils in lavage. The data for RC mice support the association of specific inflammatory cells with the development of radiation-induced lung disease and provide informative strains with which to dissect the genetic basis of these complex traits.

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.
