POU5F1 bridges Hedgehog signaling and epithelial remodeling in COPD.
Article in Frontiers in cell and developmental biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Airway epithelium remodeling is a hallmark of chronic obstructive pulmonary disease (COPD) pathogenesis. Hedgehog signaling is activated during airway epithelial repair to warrant proliferation and during cell differentiation to establish a fully functional epithelium with optimal mucociliary clearance. Consequently, it was found to be altered in COPD patients. Using transcriptomic analysis on air-liquid interface airway epithelial cells during differentiation upon Hedgehog pathway inhibition, we highlighted potential regulators of COPD-associated epithelial remodeling. Furthermore, the alteration of POU5F1 (OCT3/4) was validated in COPD airway epithelial cells and lung tissues. Although further investigations are required, these findings uncovered essential clues tethering respiratory epithelial cell plasticity and Hedgehog signaling.
