GLP-1 receptor agonist targets an AMPKα1-HIF1α-PFKFB3 metabolic vulnerability and enhances Lenvatinib response in hepatocellular carcinoma.
Article in NPJ precision 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
Glucagon-like peptide-1 receptor agonists (GLP-1RAs), widely used for diabetes and obesity, have recently attracted attention for potential anti-tumor effects, although their mechanisms remain unclear. Given their role in metabolic regulation, we hypothesized that GLP-1RAs may target cancer-specific metabolic vulnerabilities. Hepatocellular carcinoma (HCC) is characterized by metabolic reprogramming and enhanced glycolysis, which contribute to therapeutic resistance. Here, we investigated the anti-tumor effects of a GLP-1RA in HCC, focusing on its ability to modulate glycolytic pathways and enhance sensitivity to Lenvatinib. Lenvatinib-resistant HCC cells exhibited suppressed AMPKα1 and increased HIF-1α and PFKFB3 expression, promoting glycolytic adaptation. GLP-1RA treatment restored AMPKα1 activity while suppressing HIF-1α/PFKFB3 signaling, thereby reducing glycolytic activity and enhancing apoptosis. Combination treatment with GLP-1RA and Lenvatinib significantly inhibited tumor cell growth in resistant models. These findings suggest that the AMPKα1/HIF-1α/PFKFB3 axis represents a metabolic vulnerability in Lenvatinib-resistant HCC and support GLP-1RA-based combination strategies.
