Particulate Matter 2.5 Induces FGFR1-mediated Integrin Switch to Promote Non-small Cell Lung Cancer Metastasis.
Article in Cancer genomics & proteomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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/
aimParticulate matter 2.5 (PM2.5) is known to adversely affect human health. While its involvement in lung cancer pathogenesis is recognized, its specific impact on metastasis-related behaviors of lung cancer cells remains largely unexplored. MATERIALS AND
methodsIn this study, we employed cell culture models, proteomic analysis, and bioinformatic analysis. Target proteins and signaling pathways were validated using western blotting and immunofluorescence assay. Wound healing, transwell migration and phalloidin-rhodamine assays were used to determine the migratory activity.
resultsProteomic analysis identified 3,795 proteins in both control and PM2.5-treated groups. Among these, proteins associated with metastasis, particularly those related to "cell migration" (GO: 0016477), were highlighted, identifying six key proteins involved in cancer metastasis. Protein-protein interaction analysis pinpointed fibroblast growth factor receptor 1 (FGFR1) as a central target influenced by PM2.5, which promoted cell migration
conclusionThese results indicate that FGFR1 is a crucial target in PM2.5-induced metastasis in lung cancer cells, operating through an FGFR1/integrin/Akt signaling axis. This study advances our understanding of the role of PM2.5 in lung cancer metastasis and suggests potential therapeutic strategies to mitigate cancer progression.
