Sustained activation of Wnt/β-catenin signaling in the retina of form-deprived myopic chicks.
Article in BMC genomics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundForm-deprivation myopia (FDM) in chicks is one of the key models for studying myopia development. The specific molecular events and activation dynamics within the retina during early FDM stage in chicks remain unclear.
methodsRetinal transcriptome datasets (GSE161497, GSE227724) were analyzed using DESeq2 and edgeR to identify differentially expressed genes (DEGs). Protein-protein interaction networks were constructed and visualized, with hub genes identified via the Maximal Clique Centrality algorithm. Functional enrichment was analyzed. Western Blot was used to validate β-catenin and phospho-β-catenin protein expression in control, FDM 1d, and FDM 5d chick retinas.
resultsAnalysis revealed 36 common DEGs between DESeq2 and edgeR. PPI network analysis identified CTNNB1 (β-catenin), GNAQ, and TSHR as the top three hub genes. Western Blot demonstrated significant and sustained upregulation of both total β-catenin and phospho-β-catenin protein levels in FDM 1d and FDM 5d retinas compared to controls, with peak expression at FDM 5d within observed time.
conclusionThis study provides evidence of sustained activation of the Wnt/β-catenin signaling pathway specifically within the chick retina during early FDM development, highlighted by CTNNB1 as a top hub gene and confirmed by progressive increases in both total and activated β-catenin protein. This suggests a potentially conserved role for retinal Wnt/β-catenin signaling in myopia pathogenesis.
