Disruption of mc1r Disturbs Skin Pigmentation in Xenopus tropicalis.
Article in Pigment cell & melanoma research, 2025. 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
The melanocortin 1 receptor (MC1R) is well-established as a pivotal regulator of pigmentation in various species. Despite a wealth of research focused on mammals and fish, the role of Mc1r in amphibians has remained largely unexplored. This study was designed to elucidate the contribution of Mc1r in Xenopus tropicalis. Our results reveal that targeted ablation of mc1r in Xenopus tropicalis led to a significant reduction in dorsal skin pigmentation, while simultaneously accelerating the onset of melanophore pigmentation in the ventral region. This dual effect resulted in a perturbation of the canonical countershading pattern. Additionally, knockout of mc1r disrupted the expression of multiple genes primarily associated with pigmentation. Collectively, these findings underscore the critical role of MC1R in the regulation of pigmentation and the development of countershading in amphibians, contributing to the growing body of literature on the evolution and function of MC1R across vertebrate species.
