Hippo cooperates with p53 to regulate lung airway mucous cell metaplasia
Bibliographic record
Abstract
Airway mucous cell metaplasia is a significant feature of many chronic airway diseases, such as chronic obstructive pulmonary disease, cystic fibrosis and asthma. However, the mechanisms underlying this process remain poorly understood. Here, we employed in vivo mouse genetic models to demonstrate that Hippo and p53 (encoded by Trp53) cooperate to modulate the differentiation of club cells into goblet cells. We revealed that ablation of Mst1 (Stk4) and Mst2 (Stk3), encoding the core components of Hippo signaling, significantly reduces mucous metaplasia in the lung airways in a lipopolysaccharide (LPS)-induced lung inflammation murine model while promoting club cell proliferation in a Yap (Yap1)-dependent manner. Additionally, we showed that deleting Mst1/2 is sufficient to suppress p53 deficiency-mediated goblet cell metaplasia. Finally, single-cell RNA-sequencing analysis revealed downregulation of YAP and p53 signaling in goblet cells in human airways. These findings underscore the important role of Hippo and p53 signaling in regulating airway mucous metaplasia.

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.
