Network clusters analysis based on protein-protein interaction network constructed in phosgene-induced acute lung injury.
Article in Lung, 2013. 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
purposeAcute lung injury (ALI) is characterized by impairment in gas exchange and/or lung mechanics that leads to hypoxemia with the presence of diffuse pulmonary infiltrate. Assessments of lung injury play important roles in the development of rational medical countermeasures. The purpose of this study is to investigate the molecular mechanisms of phosgene-induced lung injury.
methodsWe downloaded the gene expression profile of lung tissue from mice exposed to air or phosgene from gene expression omnibus database and identified differentially expressed genes (DEGs) in ALI. Furthermore, we constructed a protein-protein interaction (PPI) network and identified network clusters.
resultsIn total, 582 DEGs were found and 4 network clusters were identified in the constructed PPI network. Gene set enrichment analysis found that DEGs were mainly involved in mitochondrion organization and biogenesis, mRNA metabolic process, negative regulation of transferase activity or catalytic activity, and coenzyme metabolic process. Pathways of spliceosome, glutathione metabolism, and cell cycle were dysregulated in phosgene-induced ALI. Besides, we identified four genes, including F3, Meis1, Pvf, and Cdc6 in network clusters, which may be used as biomarkers of phosgene-induced ALI.
conclusionsOur results revealed biological processes and pathways involved in phosgene-induced ALI and may expand understandings of phosgene-induced ALI. However, further experiments are needed to confirm our findings.
