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: Endothelial damage and NLRP3 inflammasome activation are key mechanisms underlying cerebral ischemia-reperfusion (I/R) injury. Neuregulin-1 (NRG1) alleviates endothelial damage, blood-brain barrier (BBB) disruption, and neurological deficits following acute ischemic stroke (AIS). This study investigates whether NRG1 attenuates endothelial-mesenchymal transition (EndMT) during endothelial injury by suppressing NLRP3 inflammasome activation, potentially through the AKT/NF-κB pathway, in cerebral I/R injury. Methods: Middle cerebral artery occlusion/reperfusion (MCAO/R) mouse models and oxygen-glucose deprivation/reoxygenation (OGD/R)-treated immortalized human cerebral microvascular endothelial cells (hCMEC/D3) were established and treated with NRG1. Neurological deficits were assessed using the modified Neurological Severity Score (mNSS), while cerebral infarct volume and caspase-1 activity were quantified. Cell viability and death were evaluated by the Cell Counting Kit-8 (CCK-8), lactate dehydrogenase (LDH) assays, and TUNEL staining. Protein expression was analyzed using Western blotting and immunofluorescence staining. Results: NRG1 intervention significantly improved mNSS, reduced cerebral infarct volume, and decreased caspase-1 activity in MCAO/R mice. In OGD/R-treated hCMEC/D3, NRG1 enhanced cell viability while reducing cell death, as indicated by decreased LDH release and TUNEL-positive cells. Western blotting and immunofluorescence staining revealed that NRG1 enhanced AKT phosphorylation, inhibited NF-κB p65 phosphorylation, and downregulated NLRP3 and IL-1β expression. These effects were associated with the amelioration of occludin reduction and suppression of α-smooth muscle actin (α-SMA) increase during EndMT progression. Conclusion: The results demonstrate that NRG1 reduces cerebral infarct volume, alleviates neurological deficits, and suppresses NLRP3 inflammasome activation in association with modulation of the AKT/NF-κB pathway, thereby attenuating EndMT-associated proteins following cerebral I/R injury.
