Induction of acute myeloid leukemia in mice by the human leukemia-specific fusion gene NUP98-HOXD13 in concert with Meis1
Bibliographic record
Abstract
HOX genes, notably members of the HOXA cluster, and HOX cofactors have increasingly been linked to human leukemia. Intriguingly, HOXD13, a member of the HOXD cluster not normally expressed in hematopoietic cells, was recently identified as a partner of NUP98 in a t(2;11) translocation associated with t-AML/MDS. We have now tested directly the leukemogenic potential of the NUP98-HOXD13 t(2; 11) fusion gene in the murine hematopoietic model. NUP98-HOXD13 strongly promoted growth and impaired differentiation of early hematopoietic progenitor cells in vitro; this effect was dependent on the NUP98 portion and an intact HOXD13 homeodomain. Expression of the NUP98-HOXD13 fusion gene in vivo resulted in a partial impairment of lymphopoiesis but did not induce evident hematologic disease until late after transplantation (more than 5 months), when some mice developed a myeloproliferative-like disease. In contrast, mice transplanted with bone marrow (BM) cells cotransduced with NUP98-HOXD13 and the HOX cofactor Meis1 rapidly developed lethal and transplantable acute myeloid leukemia (AML), with a median disease onset of 75 days. In summary, this study demonstrates that NUP98-HOXD13 can be directly implicated in the molecular process leading to leukemic transformation, and it supports a model in which the transforming properties of NUP98-HOXD13 are mediated through HOX-dependent pathways.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
