Modelling Robust Feedback Control Mechanisms That Ensure Reliable Coordination of Histone Gene Expression with DNA Replication.
Article in PloS one, 2016. 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
Histone proteins are key elements in the packing of eukaryotic DNA into chromosomes. A little understood control system ensures that histone gene expression is balanced with DNA replication so that histone proteins are produced in appropriate amounts. Disturbing or disrupting this system affects genome stability and gene expression, and has detrimental consequences for human development and health. It has been proposed that feedback control involving histone proteins contributes to this regulation and there is evidence implicating cell cycle checkpoint molecules activated when DNA synthesis is impaired in this control. We have developed mathematical models that incorporate these control modes in the form of inhibitory feedback of histone gene expression from free histone proteins, and alternatively a direct link that couples histone RNA synthesis to DNA synthesis. Using our experimental evidence and related published data we provide a simplified description of histone protein synthesis during S phase. Both models reproduce the coordination of histone gene expression with DNA replication during S phase and the down-regulation of histone RNA when DNA synthesis is interrupted, but only the model incorporating histone protein feedback control was able to effectively simulate the coordinate expression of a simplified histone gene family. Our combined theoretical and experimental approach supports the hypothesis that the regulation of histone gene expression involves feedback control.
