p53‐LIKE PROTEIN BINDING AFFINITY TO THE HORMONE RESPONSIVE ELEMENT OF THE HAPTOGLOBIN GENE IN FETAL RAT LIVER
Bibliographic record
Abstract
In order to identify nucleoproteins involved in transcriptional regulation of the haptoglobin (Hp) gene, fetal rat livers of dams exposed to inflammation on day 19 of pregnancy were used. Previously observed acute phase-dependent elevation of Hp gene transcriptional activity in prenatal liver was accompanied by increased binding affinities of several fetal soluble nucleoproteins and the hormone response element (RE) of the Hp gene (-170/-56). One of these proteins, a hepatic nucleoprotein of 53 kDa, was identified by Western blotting analysis as a protein within the same molecular mass and epitopes as transcription factor p53. Also, in vitro phosphorylation experiments revealed that the examined fetal nucleoprotein could be liable to the same phosphorylative post-translational modification as p53. The obtained results suggest that the fetal 53 kDa-nucleoprotein could be a homologue of transcription factor p53, participating in the transcriptional modulation of the Hp gene throughout prenatal hepatic development.

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.
