Polycyclic aromatic hydrocarbons promote tumorigenesis of gallbladder cancer via aryl hydrocarbon Receptor-HEGBC positive feedback axis
Bibliographic record
Abstract
Gallbladder cancer (GBC) is a highly aggressive tumor associated with risk factors, such as chronic infection, gallstones, and exposure to harmful chemicals. Our study explores the role of polycyclic aromatic hydrocarbons (PAHs) and long noncoding RNA HEGBC in GBC progression. We found that PAHs activate the aryl hydrocarbon receptor (AhR), which enhances HEGBC expression and promotes GBC cell proliferation, invasion, and metastasis both in vitro and in vivo . Mechanistically, AhR binds to the HEGBC promoter, establishing a positive feedback loop that further activates AhR transcription. Moreover, CYP1A1 was identified as a key downstream effector of PAHs-AhR/HEGBC-mediated proliferation, migration, and invasion of GBC cells in vitro and in vivo . These findings provide the integrative view of a molecular mechanism loop for regulating the malignant progression of GBC centered by PAHs/AhR/HEGBC, which represents a promising strategy for the treatment of GBC.

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.
