Fish Skin Mucus Vitellogenin as a Noninvasive, Sensitive Biomarker for Aquatic Xenoestrogens.

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
Environmental estrogens (EEs) can induce vitellogenin (VTG) in fish skin mucosa. However, the applicability of mucus VTG in aquatic xenoestrogen monitoring warrants comprehensive exploration. Here, we employed different estrogen exposure scenarios to compare the applicability of mucus VTG and other conventional biomarkers in zebrafish for EE monitoring. After acute exposure to 17α-ethynylestradiol (EE2) at various concentrations, mucus VTG demonstrated higher sensitivity in male zebrafish than in female zebrafish. Mucus VTG change patterns were similar to liver and blood VTG change patterns in males. Time-course exposure experiments revealed that male mucus VTG responded to EE2 much earlier than male liver and blood VTG, underlining the promise of mucus VTG as an early warning signal of aquatic estrogenicity. Exposure to multiple EEs further validated the high sensitivity of male mucus VTG. Proteomics analysis revealed that EE2 exposure potently shifted the proteome structure of male mucosa, and the VTG1 isoform was noted to be the most suitable biomarker. Overall, our results refine the roles of mucus VTG1 from male fish as a noninvasive, rapid, and sensitive biomarker of aquatic xenoestrogens, applicable to ecological risk assessment for animal welfare and ecosystem protection. Future ecological studies may only need to sample male fish mucus without sacrificing females.
