Unveiling the Molecular Mechanisms of Rosacea: Insights From Transcriptomics and In Vitro Experiments.
Article in Journal of cosmetic dermatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundRosacea is a prevalent inflammatory skin condition, but its molecular mechanisms and treatment responses remain poorly understood.
aimsThis study aims to investigate the molecular mechanisms underlying rosacea and explore drug response through transcriptomic analysis and in vitro experiments. PATIENTS/
methodsWe performed high-throughput RNA sequencing to analyze gene expression patterns in rosacea patients. In vitro experiments, including RT-qPCR, Western blot, ELISA, scratch, and Transwell assays, were used to evaluate gene and protein expression and cell behavior in HaCaT cells under simulated rosacea conditions.
resultsTranscriptomic analysis revealed significantly elevated expression of inflammatory-related genes in rosacea patients. In vitro, HaCaT cells exhibited enhanced proliferation and migration abilities, accompanied by increased expression of pro-inflammatory genes and proteins. Specifically, Toll-like receptor 2 (TLR2) and S100A9 proteins were upregulated, potentially promoting these processes.
conclusionsOur study elucidates the molecular mechanisms of rosacea, highlighting the role of inflammatory pathways and altered cell behavior in the disease. TLR2 and S100A9 may contribute to disease progression, offering potential targets for future therapeutic strategies.
