The vertebrate segmentation clock drives segmentation by stabilizing Dusp phosphatases in zebrafish.
Article in Developmental cell, 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
Pulsatile activity of the extracellular signal-regulated kinase (ERK) controls several cellular, developmental, and regenerative programs. Sequential segmentation of somites along the vertebrate body axis, a key developmental program, is also controlled by ERK activity oscillation. The oscillatory expression of Her/Hes family transcription factors constitutes the segmentation clock, setting the period of segmentation. Although oscillation of ERK activity depends on Her/Hes proteins, the underlying molecular mechanism remained mysterious. Here, we show that Her/Hes proteins physically interact with and stabilize dual-specificity phosphatases (Dusp) of ERK, resulting in oscillations of Dusp4 and Dusp6 proteins. Pharmaceutical and genetic inhibition of Dusp activity disrupt ERK activity oscillation and somite segmentation in zebrafish. Our results demonstrate that post-translational interactions of Her/Hes transcription factors with Dusp phosphatases establish the fundamental vertebrate body plan. We anticipate that future studies will identify currently unnoticed post-translational control of ERK pulses in other systems.
