High dose methylprednisolone mediates YAP/TAZ-TEAD in vocal fold fibroblasts with macrophages.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The pro-fibrotic effects of glucocorticoids may lead to a suboptimal therapeutic response for vocal fold (VF) pathology. Targeting macrophage-fibroblast interactions is an interesting therapeutic strategy; macrophages alter their phenotype to mediate both inflammation and fibrosis. In the current study, we investigated concentration-dependent effects of methylprednisolone on the fibrotic response, with an emphasis on YAP/TAZ-TEAD signaling, and inflammatory gene expression in VF fibroblasts in physical contact with macrophages. We sought to provide foundational data to optimize therapeutic strategies for millions of patients with voice/laryngeal disease-related disability. Following induction of inflammatory (M(IFN/LPS)) and fibrotic (M(TGF)) phenotypes, THP-1-derived macrophages were seeded onto HVOX vocal fold fibroblasts. Cells were co-cultured ± 0.3-3000 nM methylprednisolone ± 3 µM verteporfin, a YAP/TAZ inhibitor. Inflammatory (CXCL10, TNF, PTGS2) and fibrotic genes (ACTA2, CCN2, COL1A1) in fibroblasts were analyzed by real-time polymerase chain reaction after cell sorting. Ser211-phosphorylated glucocorticoid receptor (S211-pGR) was assessed by Western blotting. Nuclear localization of S211-pGR and YAP/TAZ was analyzed by immunocytochemistry. Methylprednisolone decreased TNF and PTGS2 in fibroblasts co-cultured with M(IFN/LPS) macrophages and increased ACTA2 and CCN2 in fibroblasts co-cultured with M(IFN/LPS) and M(TGF). Lower concentrations were required to decrease TNF and PTGS2 expression and to increase S211-pGR than to increase ACTA2 and CCN2 expression and nuclear localization of S211-pGR. Methylprednisolone also increased YAP/TAZ nuclear localization. Verteporfin attenuated upregulation of CCN2, but not PTGS2 downregulation. High concentration methylprednisolone induced nuclear localization of S211-pGR and upregulated fibrotic genes mediated by YAP/TAZ activation.
