Single-cell inflammatory signaling defines a novel CEP135
Article in Translational oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
backgroundChronic inflammation is a key driver of glioma progression, but its cellular organization within the tumor microenvironment remains poorly understood.
methodsThis study employed an integrated multi-omics analysis strategy, combining bulk transcriptomics, proteomics, and glioma cell line expression data with single-cell RNA sequencing data from paired gliomas and adjacent normal brain tissues. Inflammatory signaling activity was quantitatively assessed using pathway-level scoring methods, endothelial cell heterogeneity was analyzed at single-cell resolution, and pseudo-temporal trajectory analysis and cell-cell communication analysis were further conducted. Immunohistochemical analysis was performed using human glioma brain tissue samples from our center to independently validate key findings at the protein level.
resultsBulk transcriptomics analysis revealed significantly activated inflammatory signals in glioblastomas. Single-cell analysis identified a highly inflammatory endothelial cell subtype that was significantly enriched in tumor tissues. Cell communication analysis further revealed enhanced signal output capabilities and participation in neurally-related ligand-receptor interactions. CEP135 was specifically enriched in this endothelial cell subtype and showed consistent upregulation of both transcriptional and protein levels across multiple independent datasets. Immunohistochemical analysis of glioma brain tissue from our center confirmed that CEP135 is primarily localized in tumor-associated endothelial regions, and its expression level was significantly correlated with increasing tumor grade.High CEP135 expression was associated with poor treatment response, shorter survival outcomes.
conclusionThis study identified a innovative CEP135+inflammation-associated endothelial cell subtype and established CEP135 as a key biomarker linking endothelial inflammation reprogramming, tumor progression, and adverse clinical outcomes.
