Abstract
Although cysteine cathepsins, including cathepsin K, are sensitive to oxidation, proteolytically active forms are found at inflammatory sites. Regulation of cathepsin K activity was analyzed in the presence of H2O2 to gain an insight into these puzzling observations. H2O2 impaired processing of procathepsin K and inactivated its mature form in a time- and dose-dependent mode. However, as a result of the formation of a sulfenic acid, as confirmed by trapping in the presence of 7-chloro-4-nitrobenzo-2-oxa-1,3-diazol, approximately one-third of its initial activity was restored by dithiothreitol. This incomplete inactivation may partially explain why active cysteine cathepsins are still found during acute lung inflammation.

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
