Epigenetic therapy as a novel approach for GFI136N-associated murine/human AML
Bibliographic record
Abstract
Epigenetic changes can contribute to development of acute myeloid leukemia (AML), a malignant disease of the bone marrow. A single-nucleotide polymorphism of transcription factor growth factor independence 1 (GFI1) generates a protein with an asparagine at position 36 (GFI1(36N)) instead of a serine at position 36 (GFI1(36S)), which is associated with de novo AML in humans. However, how GFI1(36N) predisposes to AML is poorly understood. To explore the mechanism, we used knock-in mouse strains expressing GFI1(36N) or GFI1(36S). Presence of GFI1(36N) shortened the latency and increased the incidence of AML in different murine models of myelodysplastic syndrome/AML. On a molecular level, GFI1(36N) induced genomewide epigenetic changes, leading to expression of AML-associated genes. On a therapeutic level, use of histone acetyltransferase inhibitors specifically impeded growth of GFI1(36N)-expressing human and murine AML cells in vitro and in vivo. These results establish, as a proof of principle, how epigenetic changes in GFI1(36N)-induced AML can be targeted.

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.
