A High-Fidelity RNA-Targeting Cas13X Downregulates Connexin43 in Macroglia: A Novel Neuroprotective Strategy for Glaucoma.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 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 is a neurodegenerative disease characterized by the progressive degeneration of retinal ganglion cells (RGCs) and their axons, ultimately leading to irreversible vision loss. Elevated intraocular pressure (IOP) is one of the significant risk factors in glaucoma; however, neurodegeneration continues even after effective IOP management, underscoring the need for neuroprotective therapies. This study investigates the role of connexin43 (Cx43), which is extensively expressed in retinal macroglia, in regulating microglial activation and optic nerve degeneration in glaucoma. A high-fidelity CRISPR-Cas13 (hfCas13X) system is employed to selectively target and knock down Cx43 expression in macroglia. The findings reveal that Cx43-mediated ATP release through hemichannels exacerbates microglial activation and neuroinflammation, thereby contributing to RGC loss. Notably, in a mouse model of chronic ocular hypertension (COH) glaucoma, knocking down Cx43 in macroglia using the hfCas13X system significantly promoted the survival of RGCs and the integrity of the optic nerve, and improved visual function. The hfCas13X system, which offers high-fidelity RNA editing with minimal off-target effects, represents a novel and promising therapeutic strategy for glaucoma, highlighting the potential of gene editing technologies in the management of neurodegenerative diseases.
