Retinoid X receptor agonist 9CDHRA mitigates retinal ganglion cell apoptosis and neuroinflammation in a mouse model of glaucoma.
Article in FASEB journal : official publication of the Federation of American Societies for Experimental Biology, 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
Glaucoma, a leading cause of irreversible blindness, is characterized by the progressive loss of retinal ganglion cells (RGCs) and optic nerve damage, often associated with elevated intraocular pressure (IOP). Retinoid X receptors (RXRs) are ligand-activated transcription factors crucial for neuroprotection, as they regulate gene expression to promote neuronal survival via several biochemical networks and reduce neuroinflammation. This study investigated the therapeutic potential of 9-cis-13,14-dihydroretinoic acid (9CDHRA), an endogenous retinoid RXR agonist, in mitigating RGC degeneration in a high-IOP-induced experimental model of glaucoma. We administered 9CDHRA to glaucomatous mice eyes via intravitreal injections and assessed its effects on endoplasmic reticulum (ER) stress markers, glial cell activation, and RGC survival. Our findings demonstrated that 9CDHRA treatment significantly protected inner retinal function and retinal laminar structure in high-IOP glaucoma. The treatment reduced ER stress markers, increased protein lysine acetylation, and diminished glial cell activation, leading to a significant decrease in apoptotic cells under glaucomatous conditions. These results suggest that 9CDHRA exerts neuroprotective effects by modulating key pathogenic pathways in glaucoma, highlighting its potential as a novel therapeutic strategy for preserving vision in glaucoma.
