Neuroprotective Potential of the Flavonoids Quercetin and Epicatechin in a C. elegans Tauopathy Model.
Article in Molecular nutrition & food research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The prevalence of cognitive disorders such as Alzheimer's disease (AD) is increasing due to the global rise in longevity. The accumulation of amyloid β (Aβ) deposits and hyperphosphorylated Tau protein (p-Tau) are considered the main hallmarks of AD. A growing body of evidence suggests that the regular intake of flavonoid-rich foods could reduce the risk of developing AD or mitigate its progression. This study explores the potential of quercetin (Q) and epicatechin (EC) as effective molecules against AD-like pathology, using the Caenorhabditis elegans BR5270 strain, which expresses the pro-aggregant F3DK280 fragment of the human Tau protein. The results showed that after exposure to 150 µM of EC or Q, worms exhibited increased lifespan, improved chemotaxis, and delayed age-related decline in locomotion. To explore the molecular mechanisms involved, the expression of genes associated with the inhibition of p-Tau proteotoxicity were measured by RT-qPCR. It was found that Q and EC significantly increased the expression levels of autophagy-related genes and of a key gene for de novo synthesis of α- tubulin. EC and Q delay neurodegeneration in the C. elegans tauopathy model, suggesting their potential to reduce the risk of AD progression.
