CBD Disrupts Malme-3M Cell Metabolism via Glycolytic Shift and Redox Imbalance.
Article in Current issues in molecular biology, 2025. 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
backgroundAccumulating evidence suggests that cannabidiol (CBD) exerts variable effects on cancer cells that influence cellular activity, including growth. While anecdotal evidence abounds, mechanistic studies have lagged.
methodsMalme-3M cells derived from melanoma and less-aggressive BJ fibroblast cells were incubated with CBD. CE-MS mass spectroscopy was used to measure metabolite changes resulting from CBD treatment.
resultsData indicate a differential response between malignant Malme-3M cells and BJ fibroblasts with respect to metabolites critical for primary metabolic function. A significant reduction in TCA metabolites is seen with a corresponding increase in glycolytic output in the Malme-3M cell line. A similar reduction in TCA activity in BJ fibroblasts appears to differentially activate fatty acid oxidation. ATP is significantly reduced in the Malme-3M cells with a corresponding decrease in metabolites associated with redox maintenance.
conclusionsThis is the first metabolomics analyses of malignant Malme-3M cells and less-aggressive BJ fibroblasts after pre-treatment with CBD. The data suggest that the CBD-induced metabolic perturbation could reprogram cellular metabolism and affect ATP production and redox maintenance of the more-aggressive Malme-3M cells.
