Translocation of transcription regulators into the nucleus during granulocyte commitment of HL-60 cells
Bibliographic record
Abstract
Expression of transcription factors required for lineage commitment of differentiating cells (C/EBPbeta and c-Myb) and for survival of differentiated cells (STATs and NFkappaB) was examined in the HL-60 cell line. Differentiation was induced by treating the cells with retinoic acid. c-Myb expression in the nucleus restored at the precommitment stage (18 h) what concurred with the highest nuclear level of C/EBPbeta, which suggests a combinatorial interaction of these transcription factors in the granulocytic signalling pathway. Expression of STAT5a and STAT5b varied during differentiation, whereas no significant changes were seen in STAT3 levels. Increased cytosolic level of NFkappaB p65 during precommitment and commitment stages of granulocytic differentiation coincided with augmentation of the STAT5a protein level, which could be evidence of their possible cooperation during granulocytic-lineage commitment of HL-60 cells. Our results suggest that the studied transcription factors cooperatively promote signalling in the differentiating promyelocytic HL-60 cell line in response to retinoic acid.

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.
