Plasma-Derived Exosomal i-tRF-LeuCAA as Biomarker for Glioma Diagnosis and Promoter of Epithelial-Mesenchymal Transition via TPM4 Regulation.
Article in CNS neuroscience & therapeutics, 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
aimsThis study aimed to discover plasma-derived exosomal tsRNAs that serve as novel diagnostic biomarkers for glioma and to investigate the mechanism by which tsRNAs regulate glioma development.
methodsDifferentially expressed tsRNAs in the plasma exosomes of glioma patients were identified using small RNA array sequencing. Bioinformatics analyses were used to predict the biological function of tsRNAs. The changes in the phenotypes of glioma cells treated with a tsRNA mimic and inhibitor were detected. The diagnostic and prognostic characteristics of potential target genes and their related functions in gliomas were further analyzed. The cell and animal experiments were used to analyze the molecular mechanisms.
resultsAmong the 453 differentially expressed tsRNAs identified in the plasma-derived exosomes of glioma patients using small RNA sequencing, i-tRF-LeuCAA was associated with the prognosis and molecular diagnostic characteristics of glioma patients and promoted the migration, invasion, and proliferation of glioma cells and inhibited their apoptosis. In addition, TPM4 is a potential target of i-tRF-LeuCAA and is related to epithelial-mesenchymal transition in gliomas.
conclusionsi-tRF-LeuCAA could be served as a non-invasive biomarker in the diagnosis and prognosis of glioma. i-tRF-LeuCAA may indirectly regulate TPM4 expression and influence epithelial-mesenchymal transition, which may promote glioma progression.
