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

backgroundSciatic nerve injury was considered to be one of the most common peripheral nerve injuries, posing a major threat to patients. miR-874-3p previously reported to modulate key biological processes including cell proliferation, immune response, and apoptosis. However, its specific role and underlying mechanism in sciatic nerve injury remain largely uncharacterized. In this study, we demonstrated that exosomal miR‑874‑3p derived from bone marrow mesenchymal stem cells (BMSCs) alleviates key pathological features of sciatic nerve injury in a cellular model.

methodsBMSCs were isolated from Sprague Dawley rats and identified by Flow Cytometry (FCM). Exosomes were extracted from BMSCs using differential centrifugation. The morphology of BMSCs-derived exosomes was observed via TEM. The related gene and protein expression were respectively determined by qPCR and western blot. Cell viability and apoptosis were respectively assessed by CCK-8 kits and FCM. The level of ROS, MDA, SOD and GSH-Px were respectively detected using corresponding kit. Inflammatory factors were measured by ELISA. The dual-luciferase reporter assay served to determine the connection of miR-874-3p with KPNA4.

resultsmiR-874-3p was markedly upregulated in BMSCs-derived exosomes. The supplementation of BMSCs-Exos miR-874-3p maintained cell viability and diminished apoptosis. Moreover, it modulated the intracellular levels of oxidative stress-associated proteins within cells and concurrently suppressed the release of inflammatory factor, consequently decelerating neuronal impairment. Furthermore, the regulatory effects of BMSC-Exos miR-874-3p on cell proliferation, apoptosis, cytokine release, and oxidative stress were mediated by the inhibition of KPNA4, as evidenced by the fact that KPNA4 overexpression abolished these effects.

conclusionExosomal miR‑874‑3p from BMSCs alleviated OGD/R‑induced neuronal injury by targeting KPNA4.
