Curcumol ameliorates diabetic retinopathy
Article in World journal of diabetes, 2025. 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
backgroundDiabetic retinopathy (DR) is a major microvascular complication of diabetes mellitus, leading to significant visual impairment and blindness among adults. Current treatment options are limited, making it essential to explore novel therapeutic strategies. Curcumol, a sesquiterpenoid derived from traditional Chinese medicine, has shown anti-inflammatory and anti-cancer properties, but its potential role in DR remains unclear.
aimTo investigate the therapeutic effects of curcumol on the progression of DR and to elucidate the underlying molecular mechanisms, particularly its impact on the fat mass and obesity-associated (FTO) protein and the long non-coding RNA (lncRNA) MAF transcription factor G antisense RNA 1 (MAFG-AS1).
methodsA streptozotocin-induced mouse model of DR was established, followed by treatment with curcumol. Retinal damage and inflammation were evaluated through histological analysis and molecular assays. Human retinal vascular endothelial cells were exposed to high glucose conditions to simulate diabetic environments
resultsCurcumol treatment significantly reduced blood glucose levels and alleviated retinal damage in streptozotocin-induced DR mouse models. In high-glucose-treated human retinal vascular endothelial cells, curcumol inhibited cell proliferation, migration, and inflammatory responses. LncRNA microarray analysis identified MAFG-AS1 as the most upregulated lncRNA following curcumol treatment. Mechanistically, FTO demethylated MAFG-AS1, stabilizing its expression. Rescue experiments demonstrated that the protective effects of curcumol against DR were mediated through the FTO/MAFG-AS1 signaling pathway.
conclusionCurcumol ameliorates the progression of DR by modulating the FTO/MAFG-AS1 axis, providing a novel therapeutic pathway for the treatment of DR. These findings suggest that curcumol-based therapies could offer a promising alternative for managing this debilitating complication of diabetes.
