Starvation and oxidative stress resistance in <i>Drosophila</i> are mediated through the eIF4E-binding protein, d4E-BP
Bibliographic record
Abstract
eIF4E, the mRNA 5' cap-binding protein, is regulated by its binding protein (4E-BP), a downstream target of phosphatidylinositol-3-OH kinase [PI(3)K] signaling. We show that Drosophila 4E-BP (d4E-BP) activity becomes critical for survival under dietary restriction and oxidative stress, and is linked to life span. The Drosophila forkhead transcription factor (dFOXO) activates d4E-BP transcription. We show that ectopic expression of d4E-BP in dFOXO-null flies restores oxidative stress resistance to control levels. Thus, d4E-BP is an important downstream effector of a dFOXO phenotype, and regulation of translation by eIF4E is vital during environmental stress.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
