Neural Melanocortin Receptors in Fish: Insights into Growth Regulation and Aquaculture Advancement.
Review in Biomolecules, 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
Understanding and regulating fish growth is vital for the economic sustainability of aquaculture. The melanocortin-3 and -4 receptors (MC3R/MC4R, known as neural MCRs), integral components of the leptin-melanocortin circuit, play crucial roles in vertebrate energy homeostasis and growth. Abnormal neural MCR signaling contributes to human obesity. In teleosts, Mc4r was first comprehensively studied in goldfish in 2003. Since then, Mc4r has been characterized in various teleosts. Genetic and pharmacological reduction of neural Mcr signaling can increase feeding or growth in several fish models, although its aquaculture value must be evaluated using production endpoints such as feed conversion, body composition, reproduction, welfare, and biosafety. Furthermore, neural Mcrs also play a role in modulating reproductive processes and sexual function in teleosts. This review systematically examines recent progress on the roles of fish neural Mcrs, offering an overview of basic molecular characteristics, tissue distribution, and pharmacology. Physiological roles and mechanisms in growth regulation are reviewed. Finally, the potential and limitations of targeting neural Mcrs for aquaculture-relevant traits are discussed. This work contributes to our understanding of the evolution of energy homeostasis regulation in vertebrates, providing a foundation for healthier and more efficient aquaculture practices.
