Abstract
The mammalian nucleotide excision repair (NER) pathway removes dangerous bulky adducts from genomic DNA. Failure to eliminate these lesions can lead to oncogenesis, developmental abnormalities and accelerated ageing. TFIIH is a central NER factor that opens the damaged DNA through the action of its two helicases (XPB and XPD) prior to incision. Here we review our recently published data that suggest specific and distinct roles for these two helicases in NER. We also discuss the regulation of XPB and XPD enzymatic activities within TFIIH and repair complexes, and show that mutations impeding enzyme-regulator interaction contribute to genetic disorders. Understanding the fundamental molecular mechanism regulating NER is a crucial aspect of cancer therapy since the resistance to chemotherapy treatment relies on the capacities of the cell to eliminate drug-induced DNA lesions.

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
