Limonin induces ferroptosis in cervical squamous cell carcinoma by activating the expression of soluble epoxide hydrolase 2 protein.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Natural products are a rich sources for developing anti-cancer drugs with low toxicity and high efficiency. Limonin has anti-cancer activity; however, its effect on cervical squamous cell carcinoma remains unreported. The aim of this study was to explore how Limonin affects ferroptosis in cervical squamous cell carcinoma (CESC) and its underlying mechanism. Based on differential gene analysis of the Gene Expression Omnibus database and drug target prediction of the Comparative Toxicogenomics Database, combined with molecular docking technology, potential anti-cancer targets of Limonin were identified. In vitro experiments were conducted to create epoxide hydrolase 2 (EPHX2) knockdown and overexpression cell lines. Relevant phenotypic experiments were conducted to verify how Limonin targeting EPHX2 affects cell proliferation and ferroptosis. Integrated bioinformatic analysis revealed EPHX2 as a key target of Limonin. Functional experiments showed that EPHX2 overexpression inhibited the proliferation of CESC and induced ferroptosis, while Limonin treatment could enhance EPHX2 expression in a concentration-dependent manner. Furthermore, EPHX2 knockdown could reverse the inhibitory effect of Limonin on CESC proliferation and alterations in ferroptosis-related indicators. This study results reveals a new mechanism by which Limonin induces ferroptosis in CESC by activating EPHX2, providing a new strategy for natural compound-based ferroptosis-targeted therapy.
