Calycosin promotes axon growth by inhibiting PTPRS and alleviates spinal cord injury.
Article in Journal of molecular neuroscience : MN, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Our former studies have identified the alleviating effect of Calycosin (CA) on spinal cord injury (SCI). In this study, our purpose is to explore the influence of CA on SCI from the perspective of promoting axon growth. The SCI animal model was constructed by spinal cord compression, wherein rat primary cortex neuronal isolation was performed, and the axonal growth restriction cell model was established via chondroitin sulfate proteoglycan (CSPG) treatment. The expressions of axon regeneration markers were measured via immunofluorescent staining and western blot, and the direct target of CA was examined using silver staining. Finally, the expression of the protein tyrosine phosphatase receptor type S (PTPRS) was assessed using western blot. CA treatment increased neuronal process outgrowth and the expressions of axon regeneration markers, such as neurofilament H (NF-H), vesicular glutamate transporter 1 (vGlut1), and synaptophysin (Syn) in both SCI model rats and CSPG-treated primary cortical neurons, and PTPRS levels were elevated after SCI induction. In addition, PTPRS was the direct target of CA, and according to in vivo findings, exposure to CA reduced the PTPRS content. Furthermore, PTPRS overexpression inhibited CA's enhancement of axon regeneration marker content and neuronal axon lengths. CA improves SCI by increasing axon development through regulating PTPRS expression.
