Integrated screening for small molecules interfering with PKM2: a drug repurposing strategy against glioblastoma.
Article in Journal of translational medicine, 2025. 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
backgroundGlioblastoma (GBM), the most aggressive adult brain tumor, remains a significant clinical challenge. Pyruvate kinase M2 (PKM2), by shifting between its tetrameric (metabolic) and dimeric (oncogenic) forms, drives GBM metabolism and tumorigenesis, regulating the Warburg effect. This study explores a drug repurposing strategy to identify clinically approved medications capable of stabilizing PKM2 in its tetrameric form, thus disrupting GBM metabolic adaptability and oncogenic potential.
methodsWe employed a multi-step screening strategy that integrates virtual screening, pharmacological data analysis, and in vitro cellular assays performed on anchorage-dependent and -independent GBM cell lines. This methodological process highlights the potential of repurposable drugs to target a cancer-specific metabolic vulnerability, thereby accelerating the development of novel therapeutic strategies for GBM.
resultsFrom thousands of clinically approved drugs, we selected, among those potentially able to cross the blood-brain barrier, three candidates that significantly inhibited GBM cell viability, reduced PKM2 nuclear localization, and impaired glycolytic activity, suggesting their potential to attenuate the Warburg effect and tumor malignancy.
conclusionsWe established a detailed screening protocol for drug repurposing to treat GBM. This approach targets a critical vulnerability of GBM cells by disrupting their bioenergetic balance. Since metabolic reprogramming and the associated Warburg effect are hallmarks of many cancers, not just GBM, we believe this approach holds significant potential for use against a wider range of tumors.
