Translational biomarkers of hypoxic brain injury uncovered in CSF secreting human choroid plexus organoids.
Article in Fluids and barriers of the CNS, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The choroid plexus-cerebrospinal fluid (ChP-CSF) interface regulates a microenvironment supporting neural stem cell growth, strongly affected by hypoxia through ChP function. From human induced pluripotent stem cells (hiPSCs), here we established and validated in vitro ChP organoid secreting CSF-like fluid (iCSF) and exposed them to low oxygen atmosphere for 24 h. Transcriptomic indicated major data on morphological and functional alterations in the ChP cells and shotgun proteomics revealed significant changes in proteins involved in energy metabolism and mitochondrial function. We found that H2AZ and ITM2B, involved in neurogenesis and neurite growth, were the key proteins downregulated in hypoxic iCSF and ChP organoids, respectively. Positive correlation analysis between hypoxia-induced mRNA expression of the neuronal progenitor biomarkers SOX2 and PAX6. Mature neuron MAP2 and H2AZ also confirmed impairment of neurogenesis. The results from this study suggest that ChP-CSF interface opens new opportunities to characterize hypoxic brain pathophysiology and discover novel biomarkers.
