Versican regulating viscoelasticity drives pleural fibrosis via mechanotransductive signaling.

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
Extracellular matrix (ECM) disorder was believed to result from fibrosis, but it has recently been recognized that fibrotic ECM initiates a self-reinforcing circuit and contributes to the development of fibrosis. Versican, an ECM component, participates in cell-ECM interaction and ECM regeneration. In pleura, versican is primarily derived from pleural mesothelial cells (PMCs). However, the role and mechanism of versican in pleural fibrosis has remained unknown. In this study, versican and versican-mediated pleural viscoelasticity were found to be elevated in both human and murine pleural fibrotic tissues. Versican knockdown by shRNA prevented increases in viscoelasticity as well as pleural fibrosis. High levels of versican and viscoelasticity promoted mesothelial-mesenchymal transition in PMCs. Mechanistically, increased viscoelasticity induced pleural fibrosis through the CD44/USP10/Smad4 mechanotransduction pathway. In conclusion, these results revealed that excessive versican in fibrotic pleural ECM enhanced ECM viscoelasticity and consequently promoted progression of pleural fibrosis.
