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

Tumor-derived extracellular vesicles (EVs) facilitate metastatic progression by transferring bioactive cargo to recipient cells, thereby increasing endothelial permeability and promoting angiogenesis. The harsh conditions of the tumor microenvironment, such as extracellular acidosis, can alter the content of EVs, leading to changes in recipient cells, including endoplasmic reticulum (ER) stress. This study aimed to investigate whether EVs released by tumor cells adapted to acidosis or ER stress can alter endothelial functional properties. ER stress was induced in MDA-MB-231 breast cancer cells with tunicamycin, and adaptation to acidosis was achieved by culturing at pH 6.5 for 30 days. Large extracellular vesicles (LEVs) in these conditions were isolated by centrifugation. LEVs were characterized by nanoparticle tracking analysis (NTA), immunogold, Western blot, and high-performance liquid chromatography (HPLC). ER stress and autophagy markers were quantified by Western blot; cancer cells' adhesion to endothelial cells was assessed by adhesion assay; barrier permeability by dextran diffusion in an organ-on-a-chip model; migration by wound healing assay, and angiogenesis by tube formation assay. Tunicamycin was not detected in LEV from tunicamycin-treated cells (LEV T). LEV T increased the migration of endothelial cells, while not inducing ER stress, nor altering adhesion, angiogenesis, or permeability. Acidosis-adapted cells did not have greater UPR activation, but their LEVs (LEV 6.5) induced ER stress, reduced adhesion and angiogenesis, and increased permeability and migration. These findings indicate that LEVs from acidosis-adapted tumor cells reprogram endothelial physiology, supporting a potential role in metastatic progression.
