Multi-omics integrative analysis reveals the role of tumor necrosis factor superfamily member 4 in keloidal scarring.

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
objectivesTo identify aberrantly expressed immune molecules in keloids and to explore their possible biologic significance.
methodsImmune molecules with abnormal expression were identified based on immune gene sequencing of keloids, microarray datasets and high-throughput sequencing datasets and methylation microarray datasets from the Gene Expression Omnibus (GEO) database, and real-time quantitative PCR analysis.
resultsUpregulation of tumor necrosis factor superfamily member 4 (TNFSF4) in keloids was identified. Enrichment analysis found that high TNFSF4 expression was associated with immune processes, such as regulation of neutrophil chemotaxis, dendritic cell chemotaxis, and antigen processing and presentation. Single-cell RNA sequencing (scRNA) results suggested that TNFSF4 was upregulated in mesenchymal fibroblasts, which are the critical cells in skin fibrosis. This high expression of TNFSF4 enhanced cell-to-cell interactions in fibrosis-related pathways, including the fibronectin 1 (FN1) and collagen pathways. Mesenchymal fibroblasts expressing TNFSF4 significantly upregulated gene expression in extracellular matrix organization and wound healing processes.
conclusionsOur study revealed upregulation of the immune molecule TNFSF4 in keloids at the multi-omics level and its effects on intercellular crosstalk and transcriptional profiles of mesenchymal fibroblasts. Investigation of TNFSF4 as an immune checkpoint molecule may represent a new direction for keloid treatment research.
