SETDB1 and HUSH modulate Xist RNA levels during establishment of X chromosome inactivation.

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
The non-coding RNA Xist mediates X chromosome inactivation (XCI) in mammals, functioning in cis to direct heterochromatin formation over a single X chromosome in cells of early female embryos. Prior studies have determined that Xist transcription and turnover are modulated to maintain the correct level of Xist RNA to inactivate a single X chromosome. The underlying molecular mechanisms are poorly understood. In this study we demonstrate that RNA-dependent recruitment of the H3K9me3 methyltransferase SETDB1 and the HUSH complex across the transcribed Xist locus functions to suppress Xist transcription during establishment of XCI. Thus, degron-mediated acute depletion of SETDB1 or core HUSH subunits abrogates allelic H3K9me3 deposition, increasing Xist transcription, accumulation of Xist RNA, and the rate of X-linked gene silencing. Our findings support a model in which the SETDB1/HUSH pathway coordinates Xist transcription rates to maintain optimal Xist RNA levels, ensuring the silencing of a single X chromosome.
