Cannabidiol Suppresses Glioma Growth and Limits Invasion Partly Through an LOXL2-Associated EMT-Like Program.
Article in BioMed research international, 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
backgroundGliomas, particularly glioblastoma, remain difficult to control because diffuse infiltration into surrounding brain tissue limits complete resection and contributes to recurrence. Cannabidiol (CBD), a nonpsychoactive cannabinoid capable of entering the central nervous system, has shown antitumor activity in glioma models, but the mechanisms underlying its anti-invasive effects remain unclear. Lysyl oxidase-like 2 (LOXL2) regulates extracellular-matrix remodeling and mesenchymal phenotypes in several cancers. We therefore tested the hypothesis that CBD limits glioma growth and invasion partly by suppressing an LOXL2-associated extracellular-matrix and EMT-like program.
methodsHuman U87 and murine GL261 glioma cells were used to examine CBD effects on tetrazolium-based cell viability, clonogenic growth, cell-cycle progression, apoptosis, migration, and invasion. The two cell lines provided complementary human and murine models, and the immunocompetent intracranial GL261 model enabled syngeneic in vivo validation. RNA sequencing and public glioma datasets were used to identify and contextualize CBD-responsive molecules. Mechanistic involvement was tested by determining whether LOXL2 knockdown phenocopied and LOXL2 overexpression attenuated the anti-invasive effects of CBD.
resultsCBD reduced glioma-cell viability and clonogenicity, induced G1-phase arrest and apoptosis, and suppressed migration and invasion. C CCK-8-derived IC
conclusionsCBD suppresses glioma growth and limits invasion, at least in part, by attenuating an LOXL2-associated EMT-like and extracellular-matrix-remodeling program. Because LOXL2 overexpression produced only a partial rescue and direct target engagement was not tested, LOXL2 should be interpreted as a functional mediator rather than the sole or direct molecular target of CBD. These findings support further validation in patient-derived and pharmacokinetically informed glioma models.
