Mouse EWSR1 is crucial for spermatid post-meiotic transcription and spermiogenesis.

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
Spermatogenesis is precisely controlled by complex gene-expression programs. During mammalian male germ-cell development, a crucial feature is the repression of transcription before spermatid elongation. Previously, we discovered that the RNA-binding protein EWSR1 plays an important role in meiotic recombination in mouse, and showed that EWSR1 is highly expressed in late meiotic cells and post-meiotic cells. Here, we used an Ewsr1 pachytene stage-specific knockout mouse model to study the roles of Ewsr1 in late meiotic prophase I and in spermatozoa maturation. We show that loss of EWSR1 in late meiotic prophase I does not affect proper meiosis completion, but does result in defective spermatid elongation and chromocenter formation in the developing germ cells. As a result, male mice lacking EWSR1 after pachynema are sterile. We found that, in Ewsr1 CKO round spermatids, transition from a meiotic gene-expression program to a post-meiotic and spermatid gene expression program related to DNA condensation is impaired, suggesting that EWSR1 plays an important role in regulation of spermiogenesis-related mRNA synthesis necessary for spermatid differentiation into mature sperm.
