DNA replication fork speed acts as a pacer in cortical neurogenesis.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
DNA replication fork speed, which controls the rate of genome duplication, has emerged as a key regulator of cellular plasticity. However, its role in neurogenesis remains unexplored. Mini-chromosome maintenance complex (MCMs)-binding protein (MCMBP) functions as a chaperone for newly synthesized MCMs, increasing chromatin coverage to restrain fork speed. We demonstrate that selectively deleting Mcmbp in neural progenitor radial glial cells (RGCs) accelerates fork speed, triggering DNA damage, micronuclei formation, and widespread apoptosis, which ultimately activates p53 and causes microcephaly. Unexpectedly, concurrent deletion of Trp53 and Mcmbp further increases fork speed, leading to extensive RGC detachment from the ventricular zone and acquisition of outer-RGC characteristics. Mechanistically, we find that the MCM complex coordinates DNA and centrosome duplication, thereby mediating RGC attachment. Behavioral analysis reveals that embryonic replication stress induced by accelerated fork speed results in lasting anxiety-like behavior in adult mice. These findings unveil a role for replication fork speed in neurogenesis.
