1 · What the graph read from it

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.

2 · The registry

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

Goblet cell hyperplasia and metaplasia and excessive mucus are prominent pathologies of chronic airway diseases such as chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF), and chronic bronchitis. Chronic infection by respiratory pathogens, including Pseudomonas aeruginosa, exacerbates cyclical proinflammatory responses and mucus hypersecretion. P. aeruginosa and its virulence factor pyocyanin contribute to these pathologies by inhibiting FOXA2, a key transcriptional regulator of mucus homeostasis, through activation of antagonistic signaling pathways EGFR-AKT/ERK1/2 and IL-4/IL-13-STAT6-SPDEF. However, FOXA2-targeted therapy has not been previously explored. Here, we examined the feasibility of repurposing the incretin mimetic Exendin-4 to restore FOXA2-mediated airway mucus homeostasis. We have found that Exendin-4 restored FOXA2 expression, attenuated mucin production in COPD and CF-diseased airway cells, and reduced mucin and P. aeruginosa burden in mouse lungs. Mechanistically, Exendin-4 activated the GLP1R-PKA-PPAR-γ-dependent phosphatases PTEN and PTP1B, which inhibited key kinases within both EGFR and STAT6 signaling cascades. Our results may lead to the repurposing of Exendin-4 and other incretin mimetics to restore FOXA2 function and ultimately regulate excessive mucus in diseased airways.
