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

Proper regulation of X-linked gene expression, termed dosage compensation, is required for the normal development of mammalian embryos. Through the process of X chromosome inactivation (XCI), somatic cells of mammalian females inactivate one of their two X chromosomes in order to balance X-linked gene dosage with their male counterparts. The process of XCI is dependent upon the long non-coding RNA Xist, which is expressed from and coats the inactivated X chromosome (Xi) in cis. During mouse embryogenesis, imprinted XCI inactivates the paternally inherited X chromosome (Xp) within the extra-embryonic lineages. Consequently, females harboring a paternally derived Xist mutation (X/X(Xist-)) die owing to failure of imprinted XCI and, presumably, poor trophoblast development. Here, we investigate the consequence of two active X chromosomes in the extra-embryonic ectoderm (ExE) of X/X(Xist-) female embryos. At embryonic day (E) 6.5, we find that the X/X(Xist-) ExE lacks the transcriptional regulator CDX2, a factor required to maintain the ExE in a progenitor state. In addition, spongiotrophoblast progenitors are not maintained. Surprisingly, we observe evidence of an Xi in a subpopulation of X/X(Xist-) ExE cells. We demonstrate further that trophectodermal stem cells derived from X/X(Xist-) embryos completely reverse normal imprinted XCI patterns. Taken together, our data suggest that, much like in the cells of the epiblast, the initial imprint that establishes imprinted XCI is probably erased in ExE cells. Conversely, unlike the epiblast, in which XCI is not required for progenitor cell maintenance, we demonstrate that dosage compensation is indispensable for the maintenance of trophoblast progenitors.
