The umbilical cord blood exosome MFG-E8 alleviates hypoxic-ischemic encephalopathy brain injury in neonatal rats by restoring autophagy flux and inhibiting ferroptosis through GSK3β/β-catenin signaling.

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
Background: Recent studies have revealed importance of human umbilical cord blood (HUCB)-derived exosomes (HUCB-Exo) in central nervous system diseases, but the role of HUCB-Exo in hypoxic-ischemic encephalopathy (HIE) remains unclear. This study aims to explore the mechanisms of HUCB-Exo in HIE. Methods: HIE models were constructed in 7-day-old neonatal rats using classical Rice-Vannucci modeling, and SH-SY5Y cells were induced by oxygen-glucose deprivation/reperfusion (OGD/R) injury, followed by intervention with HUCB and HUBC-Exo, either non-transfected or transfected with si-NC/si-MFG-E8. Results: HUBC-Exo decreased cerebral infarct size and cerebral water content in HIE neonatal rats and improved short-term and long-term neurological function. HUBC-Exo down-regulated Beclin1, ATG7, and LC3 II/I expression, while promoting p62 expression in HIE neonatal rats. After HUBC-Exo treatment, NCOA4 and ACSL4 expression in HIE neonatal rats decreased, while FTH1, SLC7A11, and GPX4 expression were increased. In addition, HUBC-Exo decreased Fe Conclusion: Our results suggested that HUBC-Exo-transmitted MFG-E8 inhibited autophagy and ferroptosis through GSK3β/β-catenin signaling, thereby alleviating brain injury in HIE neonatal rats, which provided a new idea for treating HIE.
