Targeting DNA methylation: molecular and in vivo evidence for quinoa and chia nanocapsules as epigenetic modulators in DMBA-treated rats.
Article in NPJ science of food, 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
This study investigated the modulating role of quinoa and chia nanocapsules on the DMBA-induced DNA methylation in rats. Theoretical docking was conducted to assess the binding affinities of selected phytoconstituents from quinoa and chia against the active sites of DNMT1 and TET2. An in vivo study was conducted to determine the effect of nanocapsules on DMBA-induced LINE-1 DNA methylation patterns. Molecular docking suggested that all selected compounds have high binding affinity for DNMT1, with linoleic acid being the top-rate TET2 inhibitor. The in vivo study demonstrated that quinoa nanocapsules can potentially reverse the DMBA-induced LINE-1 methylation pattern in the liver and kidney. Chia nanocapsules did not change the methylation status in the kidney; however, they partially modulated it in the liver. Our findings show that DMBA-induced LINE-1 DNA methylation in the kidney and liver is reversible via quinoa nanocapsules, and is likely driven by their active phytochemicals.
