JAG1/Notch Pathway Inhibition Induces Ferroptosis and Promotes Cataractogenesis.
Article in International journal of molecular sciences, 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
Cataracts remain the leading cause of visual impairment worldwide, yet the underlying molecular mechanisms, particularly in age-related cataracts (ARCs), are not fully understood. The Notch signaling pathway, known for its critical role in various degenerative diseases, may also contribute to ARC pathogenesis, although its specific involvement is unclear. This study investigates the role of Notch signaling in regulating ferroptosis in lens epithelial cells (LECs) and its impact on ARC progression. RNA sequencing of anterior lens capsule samples from ARC patients revealed a significant downregulation of Notch signaling, coupled with an upregulation of ferroptosis-related genes. Notch1 expression decreased, while ferroptosis markers increased in an age-dependent manner. In vitro, upregulation of Notch signaling alleviated ferroptosis by decreasing ferritin heavy chain 1 (FTH1) and p53 levels while enhancing the expression of nuclear factor erythroid 2-related factor 2 (Nrf2), glutathione peroxidase 4 (GPX4), and solute carrier family 7 member 11 (SLC7A11). Conversely, inhibition of Notch signaling exacerbated ferroptosis, as evidenced by reduced Nrf2, GPX4, and SLC7A11 expression. These findings suggest that downregulation of Notch signaling promotes ferroptosis in LECs by impairing the Nrf2/GPX4 antioxidant pathway, thereby contributing to ARC development. This study offers new insights into ARC pathogenesis and highlights the Notch signaling pathway as a potential therapeutic target for preventing or mitigating ARC progression.
