1 · What the graph read from it

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.

2 · The registry

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

Iron metabolism is critical for sustaining life and maintaining human health. Here, we find that iron homeostasis is linked to facultative heterochromatin assembly and regulation of gene expression during adaptive genome control. We show that the fission yeast Clr4/Suv39h histone methyltransferase is part of a rheostat-like mechanism in which transcriptional upregulation of mRNAs in response to environmental change provides feedback to prevent their uncontrolled expression through heterochromatin assembly. Interestingly, proper iron homeostasis is required, as iron depletion or downregulation of iron transporters causes defects in heterochromatin assembly and unrestrained upregulation of gene expression. Remarkably, an unbiased genetic screen revealed that restoration of iron homeostasis is sufficient to re-establish facultative heterochromatin and proper gene control genome-wide. These results establish a role for iron homeostasis in facultative heterochromatin assembly and reveal a dynamic mechanism for reprogramming the genome in response to environmental changes.
