No <i>ING1</i> mutations in human brain tumours but reduced expression in high malignancy grades of astrocytoma
Bibliographic record
Abstract
The ING1 family of proteins has been shown to have regulatory functions in oncogenesis, apoptosis, DNA repair and cell cycle regulation. Here we present the first report on LOH analysis of the ING1 locus, mutation analysis of the complete coding sequence including intron-exon boundaries and expression analysis of the different ING1 splice products and protein isoforms in primary brain tumours. No somatic ING1 mutations were detected. Semi-quantitative analysis revealed higher levels of p33ING1b RNA in benign than in malignant lesions. This correlation was significant in a subset of 37 astrocytic tumours WHO grades I to IV. ING1 protein isoforms p47ING1a, p33ING1b and p24ING1c were found to be expressed variably in this series. Our findings support a regulatory contribution of ING1 to the development or progression of brain tumours.

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.
