Targeting Methionine Metabolism Reveals AMPK-SAMTOR Signaling as a Therapeutic Vulnerability in Prostate Cancer.
Article in Biology, 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
Prostate cancer (PCa) is not only one of the most diagnosed malignancies in men but also a leading cause of cancer-related mortality globally. PCa exhibits unique metabolic dependencies, particularly on lipids and glutamine, unlike many solid tumors, rather than glycolysis. Methionine metabolism plays a crucial role in these metabolic pathways, contributing to polyamine biosynthesis, DNA methylation, and cellular signaling processes. Here, we demonstrate that methionine deprivation induces selective vulnerability in AMPK-deficient PC3 PCa cells by disrupting SAMTOR-mTOR signaling and triggering oxidative stress, lipid depletion, and autophagic responses. Through functional and proteomic analyses, we show that SAMTOR directly interacts with p-AMPK and modulates cell fate under methionine-limited conditions. Our findings establish a mechanistic link between methionine sensing and metabolic stress signaling in PCa, offering a new avenue for targeted intervention.
