NOX2 mediates NLRP3/ROS facilitating nasal mucosal epithelial inflammation in chronic rhinosinusitis with nasal polyps.
Article in Heliyon, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Background: Previous investigations have provided limited insight into the role of oxidative stress in nasal mucosa inflammation. The aim of this study was to investigate the mechanism of oxidative stress in the epithelial cells of chronic rhinosinusitis with nasal polyps CRSwNP utilizing single-cell RNA sequencing data. Methods: Single-cell RNA sequencing data from HRA000772 were used to assess oxidative stress, inflammasome activation, and nicotinamide adenine dinucleotide phosphate oxidases (NOXs) expression in epithelial cells via integrative rank-based gene set enrichment analysis. The localization of reactive oxygen species (ROS) and NOX2 in nasal mucosa and cell models was visualized using fluorescent probes and immunohistochemistry, respectively. Functional studies on NOX2 involved siRNA and plasmid transfections Results: Single-cell RNA sequencing data suggested an increase of oxidative stress score and NLRP3 inflammasome score in CRSwNP epithelial cells. Vitro experiments demonstrated that lipopolysaccharide could induce ROS accumulation, NLRP3 inflammasome activation and epithelial alarmin expression. MCC950 inhibited the expression of epithelia alarmin Conclusion: This study highlights the crucial role of NOX2 as a key regulator of ROS accumulation and NLRP3 inflammasome activation in CRSwNP, underscoring its potential as a valuable therapeutic target for CRSwNP.
