Identification of human polo-like kinase 1 as a potential therapeutic target in pancreatic cancer
Bibliographic record
Abstract
Pancreas cancer is the fourth leading cause of cancer-related death in adults in the United States. New molecular targets for diagnosis and therapy of this disease are desperately needed. In this study, we report on the mitotic serine-threonine kinase polo-like kinase 1 (Plk1) in pancreatic cancer. Plk1 mRNA was found to be overexpressed in 9 of 10 tested pancreatic cancer cell lines and in 4 of 4 tested human tumors. Immunohistochemical staining of a pancreatic tissue microarray showed that 26 of the 35 tumors taken directly from patients overexpressed Plk1. We also examined the effects of depleting Plk1 in pancreatic cancer cells by the use of antisense oligonucleotides. Antisense-treated pancreatic cancer cells showed cell cycle arrest in G(2)-M as well as a drastic reduction in proliferation rates. These data suggest that Plk1 is a potential therapeutic target in devising a treatment for patients with pancreatic cancer.

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.
