Astragaloside IV protects brain cells from ischemia-reperfusion injury by inhibiting ryanodine receptor expression and reducing the expression of P-Src and P-GRK2.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Astragaloside IV, a prime active component of Astragalus membranaceus, has potential as a neuroprotectant. We aimed to identify the active ingredients in A. membranaceus and assess if Astragaloside IV can improve cerebral ischemia-reperfusion injury (CIRI) cell apoptosis by reducing P-Src and P-GRK2 via ryanodine receptor (RyR) expression inhibition. We used bioinformatics analysis to examine the effects of A. membranaceus on ischemic stroke. We studied brain samples from middle cerebral artery occlusion (MCAO) mice treated with normal saline, Astragaloside IV, and sham mice for pathology and Western blot tests. We also tested PC12 cells in vitro with or without Astragaloside IV or GSK180736A using Western blotting and fluorescence assays. Our bioinformatics analysis suggested a possible association between A. membranaceus, calcium ion pathways, and apoptosis pathways. Western blot data indicated Astragaloside IV significantly decreased RyR, p-Src, and downstream phosphorylated GRK2, PLC, CaMKII, and IP3R levels in MCAO mice brains. Astragaloside IV also considerably inhibited pro-apoptotic and oxidative stress-associated proteins' expression while boosting anti-apoptotic protein expression. The results suggest Astragaloside IV can inhibit RyR expression, subsequently reducing brain cell apoptosis.
