Dynamics of DNA Methylation Reprogramming Influenced by X Chromosome Dosage in Induced Pluripotent Stem Cells.
Article in Epigenetics insights, 2018. 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
How the epigenome of one cell type is remodeled during reprogramming into another unrelated type of cell remains unclear. Overexpression of transcription factors in somatic cells enables the induction of induced pluripotent stem cells (iPSCs). This process entails genome-wide remodeling of DNA methylation, chromatin, and transcription. Recent work suggests that the number of active X chromosomes present in a cell influences remodeling of DNA methylation during somatic cell reprogramming to mouse iPSCs. Female iPSCs with 2 active X chromosomes display global DNA hypomethylation, whereas male XY iPSCs show DNA methylation levels similar to the somatic cells they are derived from. Global DNA methylation erasure in female iPSCs takes place genome-wide and involves repression of DNA methyltransferases. However, on loss of one X chromosome, female iPSCs acquire a DNA methylation landscape resembling that of XY iPSCs. Therefore, it is the X chromosome dosage that dictates global DNA methylation levels in iPSCs. Here, we discuss the evidence that links X chromosome dosage with the regulation of DNA methylation in pluripotent stem cells. We focus on iPSCs reprogramming studies, where X chromosome status is a novel factor impacting our understanding of epigenetic remodeling.
