M1 Macrophage-Derived Extracellular Particles Induce Cell Death in MDA-MB-231 Cells.
Article in Cancer reports (Hoboken, N.J.), 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
backgroundTriple-negative breast cancer (TNBC), a leading cause of female mortality worldwide, presents a treatment challenge due to the lack of targeted receptors. Macrophages, recognized for their role in the immune response, provide a promising avenue for cancer research. Given that macrophages secrete extracellular particles (EPs), which have been implicated in biological processes, including intercellular communication and immune modulation, it is hypothesized that EPs derived from macrophages could have potential anticancer effects.
aimsThis study examines the effect of M1 macrophage-secreted EPs on TNBC cells to investigate their potential as a therapeutic. METHODS AND
resultsPolarization was induced in RAW 264.7 macrophages and characterized using ELISA, nitrite release, and microscopy. Macrophage-derived EPs were isolated and characterized using nanoparticle tracking analysis, electron microscopy, and western blotting. The influence of EPs on MDA-MB-231 cells, a TNBC model, was assessed using confocal microscopy. Results showed the increasing expression of caspase 3/7 in a time-dependent manner (0, 24, and 48 h). Cell death was observed in TNBC cells with M1 macrophage-derived EPs, while cell proliferation was observed when M2 macrophage-derived EPs interacted with MDA-MB-231 cells.
conclusionOverall, results showed that EPs derived from M1 macrophages could induce cell death in MDA-MB-321 cells, opening up potential options for new treatments in TNBC.
