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

Background: Ischemia-reperfusion injury (IRI) is a leading contributor to acute kidney injury (AKI), resulting in severe renal dysfunction and increased mortality. Despite progress in medical research, effective therapies for IRI remain limited. Recently, small extracellular vesicles (sEVs) originating from human umbilical cord mesenchymal stem cells (HucMSC-sEVs) have gained attention as potential therapeutic agents for alleviating organ damage. This study aimed to investigate the protective effects of HucMSC-sEVs in renal IRI and explore the underlying mechanisms involved. Methods: HucMSC-sEVs were isolated from HucMSCs via differential ultracentrifugation. Their characteristics were analyzed via transmission electron microscopy (TEM), nanoFCM, and western blotting. The protective effects of HucMSC-sEVs on OGD/R-induced apoptosis in HK-2 cells were evaluated via western blotting and flow cytometric analysis. Additionally, to explore the molecular mechanisms, qRT-PCR, dual-luciferase reporter assays, and other techniques were employed to investigate the role of miR-202-5p in HucMSC-sEVs, with a focus on its ability to regulate the PI3K/AKT pathway through the targeting of GOLIM4. Finally, the therapeutic effects of HucMSC-sEVs were evaluated Results: The HucMSC-sEVs exhibited a characteristic biconcave circular morphology, with a particle size range of 60-100 nm and an average diameter of 79.8 nm. Western blotting confirmed the presence of sEV markers CD9 and TSG101, and HucMSC-sEVs were efficiently taken up by HK-2 cells. In the OGD/R model, HucMSC-sEVs significantly reduced apoptosis, attenuated the expression of BAX and CC3, and promoted the upregulation of BCL-2. Mechanistic studies revealed that HucMSC-sEVs deliver miR-202-5p, which targets GOLIM4 and activates the PI3K/AKT pathway, ultimately reducing renal tubular cell apoptosis. In the mouse IRI model, HucMSC-sEVs significantly alleviated kidney damage and reduced the serum creatinine and urea nitrogen levels. Conclusion: This study is the first to demonstrate the role of HucMSC-sEVs in attenuating renal IRI both
