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

Asymmetrically dividing muscle stem cells in skeletal muscle give rise to committed cells, where the myogenic determination factor Myf5 is transcriptionally activated by Pax7. This activation is dependent on Carm1, which methylates Pax7 on multiple arginine residues, to recruit the ASH2L:MLL1/2:WDR5:RBBP5 histone methyltransferase complex to the proximal promoter of Myf5. Here, we found that Carm1 is a specific substrate of p38γ/MAPK12 and that phosphorylation of Carm1 prevents its nuclear translocation. Basal localization of the p38γ/p-Carm1 complex in muscle stem cells occurs via binding to the dystrophin-glycoprotein complex (DGC) through β1-syntrophin. In dystrophin-deficient muscle stem cells undergoing asymmetric division, p38γ/β1-syntrophin interactions are abrogated, resulting in enhanced Carm1 phosphorylation. The resulting progenitors exhibit reduced Carm1 binding to Pax7, reduced H3K4-methylation of chromatin, and reduced transcription of Myf5 and other Pax7 target genes. Therefore, our experiments suggest that dysregulation of p38γ/Carm1 results in altered epigenetic gene regulation in Duchenne muscular dystrophy.
