Decreased expression of the INK4 family of cyclin‐dependent kinase inhibitors in Wilms tumor
Bibliographic record
Abstract
Cyclin-dependent kinase (CDK) inhibitors represented by the INK4 family (including p16(INK4a, CDKN2A), p15(INK4b, CDKN2B), p18(INK4c, CDKN2C), and p19(INK4d, CDKN2D)) are regulators of the cell cycle shown to be aberrant in many types of human cancer. We tested the hypothesis that these CDK inhibitors are a target for altered gene expression in Wilms tumor. Using RT-PCR, gene expression of the INK4 family was found to be decreased in 9 of 38 Wilms tumor samples obtained from the National Wilms Tumor Study Group (NWTSG) tissue bank. All the affected tumor samples were of favorable histology. Methylation-specific PCR revealed that methylation in the p16 promoter region may be responsible for altered expression. The incidence of loss of p16 expression may increase with increasing tumor stage, i.e., 1/10 (10%) with stage I/II FH Wilms tumor, 2/10 (20%) with stage III FH Wilms tumor, and 4/10 (40%) with stage IV FH Wilms tumor. Thus, determining the expression status of the INK4 family may have potential prognostic value in the management of Wilms tumor.

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.
