The Tumor Suppressor BAP1 Regulates the Hippo Pathway in Pancreatic Ductal Adenocarcinoma
Bibliographic record
Abstract
Abstract The deubiquitinating enzyme BAP1 is mutated in a hereditary cancer syndrome with a high risk for mesothelioma and melanocytic tumors. Here, we show that pancreatic intraepithelial neoplasia driven by oncogenic mutant KrasG12D progressed to pancreatic adenocarcinoma in the absence of BAP1. The Hippo pathway was deregulated in BAP1-deficient pancreatic tumors, with the tumor suppressor LATS exhibiting enhanced ubiquitin-dependent proteasomal degradation. Therefore, BAP1 may limit tumor progression by stabilizing LATS and thereby promoting activity of the Hippo tumor suppressor pathway. Significance: BAP1 is mutated in a broad spectrum of tumors. Pancreatic Bap1 deficiency causes acinar atrophy but combines with oncogenic Ras to produce pancreatic tumors. BAP1-deficient tumors exhibit deregulation of the Hippo pathway.

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.
