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

Growing mammalian oocytes accumulate substantial amounts of RNA, most of which is degraded during subsequent meiotic maturation. The growth-to-maturation transition begins with germinal vesicle or nuclear envelope breakdown (GVBD) and is critical for oocyte quality and early development. The molecular machinery responsible for the oocyte transcriptome transition remains unclear. Here, we report that an exosome-associated RNase, EXOSC10, sculpts the transcriptome to facilitate the growth-to-maturation transition of mouse oocytes. We establish an oocyte-specific conditional knockout of Exosc10 in mice using CRISPR/Cas9 which results in female subfertility due to delayed GVBD. By performing multiple single oocyte RNA-seq, we document dysregulation of several types of RNA, and the mRNAs that encode proteins important for endomembrane trafficking and meiotic cell cycle. As expected, EXOSC10-depleted oocytes have impaired endomembrane components including endosomes, lysosomes, endoplasmic reticulum and Golgi. In addition, CDK1 fails to activate, possibly due to persistent WEE1 activity, which blocks lamina phosphorylation and disassembly. Moreover, we identified rRNA processing defects that cause higher percentage of developmentally incompetent oocytes after EXOSC10 depletion. Collectively, we propose that EXOSC10 promotes normal growth-to-maturation transition in mouse oocytes by sculpting the transcriptome to degrade RNAs encoding growth-phase factors and, thus, support the maturation phase of oogenesis.
