BCL2 and related prosurvival proteins require BAK1 and BAX to affect autophagy
Bibliographic record
Abstract
It is widely thought that prosurvival BCL2 family members not only inhibit apoptosis, but also block autophagy by directly binding to BECN1/Beclin 1. To distinguish whether BCL2, BCL2L1/BCL-XL, or MCL1 influence autophagy directly, or indirectly, through their effects on apoptosis, we compared normal cells to those lacking BAX and BAK1. In cells able to undergo mitochondria-mediated apoptosis, inhibiting the endogenous prosurvival BCL2 family members induces both autophagy and cell death, but when BAX and BAK1 are deleted, neither inhibiting nor overexpressing BCL2, BCL2L1, or MCL1 causes any detectable effect on LC3B lipidation, LC3B turnover, or autolysosome formation. These results show that prosurvival BCL2 family members influence autophagy only indirectly, by inhibiting activation of BAX and BAK1.

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.
