Angiotensin II Receptor-Associated Protein (AGTRAP) Enhances Glioma Cell Survival Through the IL-6/JAK2/STAT3 Pathway and Correlates With an Immunosuppressive Microenvironment.
Article in CNS neuroscience & therapeutics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
aimThere is an urgent need for actionable therapeutic targets for glioma. Angiotensin II receptor-associated protein (AGTRAP) is upregulated in glioma, but its functional role and downstream programs remain insufficiently defined. This study aimed to clarify the clinical relevance, biological function, and mechanism of AGTRAP in glioma.
methodsAGTRAP expression and clinicomolecular associations were analyzed across public glioma cohorts. Loss-of-function studies were performed in glioma cells (A172 and U251), followed by proliferation and apoptosis assays. Recombinant IL-6 was used for rescue experiments. An orthotopic xenograft model was used to evaluate tumor growth in vivo.
resultsAGTRAP expression is significantly elevated in gliomas versus normal brain tissues and correlates with tumor grade, age, 1p/19q co-deletion, and IDH mutations. High AGTRAP expression predicted poorer survival. AGTRAP knockdown suppressed proliferation, increased apoptosis, reduced IL-6 mRNA and protein levels, and attenuated JAK2/STAT3 activation. Recombinant IL-6 partially restored JAK2/STAT3 signaling and mitigated the growth-inhibitory phenotype caused by AGTRAP silencing. In vivo, AGTRAP knockdown reduced tumor burden. Transcriptome-based analyses showed that AGTRAP expression was associated with a myeloid/macrophage-enriched microenvironment, and exploratory analyses suggested cross-tumor associations between AGTRAP expression and checkpoint blockade outcomes.
conclusionAGTRAP supports glioma cell survival by engaging an IL-6-linked JAK2/STAT3 program and is associated with a macrophage-rich, inflammatory tumor microenvironment. These findings suggest that AGTRAP may serve as a candidate intervention target for gliomas.
