1 · What the graph read from it

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.

2 · The registry

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 a leading male malignancy worldwide, with metabolic reprogramming being a critical hallmark of its progression. Extracellular vesicles (EVs) derived from tissues directly reflect the tumor microenvironment, offering unique insights into cancer pathophysiology that are unattainable through cell line or biofluid-derived EVs. However, the functional roles of tissue-derived EVs in PCa metabolism remain poorly understood. Leveraging our expertise in murine PCa model establishment and EV isolation from prostate tissue, this study aimed to characterize functional differences between PCa and normal prostate tissue via proteomic analysis of tissue-derived sEVs. We orthotopically implanted luciferase-labeled PCa cells into nude mice to establish an in situ PCa model, confirmed tumor formation via in vivo imaging, and harvested tissues after 4 weeks. sEVs were isolated using ultracentrifugation combined with an iodixanol density cushion and characterized by transmission electron microscopy, nanoparticle tracking analysis, and protein marker profiling. Proteomic analysis identified 28 upregulated and 24 downregulated proteins in PCa-derived sEVs compared to normal controls. Subcellular localization revealed enrichment in the cytoplasm, while pathway analysis highlighted significant involvement in metabolic processes, particularly glycolysis, amino acid biogenesis, carbon metabolism, and pyruvate metabolism. Our study establishes a robust method for isolating prostate tissue sEVs and provides the first evidence that PCa tissue-derived sEVs exhibit profound metabolic pathway alterations. These findings enhance our understanding of PCa progression mechanisms and may facilitate the development of novel diagnostic biomarkers and therapeutic strategies targeting metabolic dysregulation in PCa. SUMMARY: In this study, we created a method to isolate prostate tissue small EVs, based on our knowledge of the murine prostate cancer model building. Our data suggested that prostate tissue small EVs proteins significantly changed in many metabolism pathways, such as Glycolysis, Biogenesis of amino acids, Carbon metabolism and Pyruvate metabolism. In this study, we are the first to report prostate tissue-derived EVs proteins enriched in alterations of cancer metabolism. These differential proteins in PCa tissue EVs reflect metabolic changes in PCa and may provide insights into the development of early diagnostic biomarkers or novel therapeutic strategies.
