c-Abl Tyrosine Kinase Regulates Caspase-9 Autocleavage in the Apoptotic Response to DNA Damage
Bibliographic record
Abstract
Activation of the initiator caspase-9 is essential for induction of apoptosis by developmental signals, oncogenic transformation, and genotoxic stress. The c-Abl tyrosine kinase is also involved in the apoptotic response to DNA damage. The present results demonstrate that c-Abl binds directly to caspase-9. We show that c-Abl phosphorylates caspase-9 on Tyr-153 in vitro and in cells treated with DNA damaging agents. Moreover, inhibition of c-Abl with STI571 blocked DNA damage-induced autoprocessing of caspase-9 to the p35 subunit and activation of caspase-3. Caspase-9(Y153F) also attenuated DNA damage-induced processing of caspase-9 to p35, activation of caspase-3, and apoptosis. These findings indicate that caspase-9 autoprocessing is regulated by c-Abl in the apoptotic response to genotoxic stress.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
