PABPN1L is required for maternal mRNA degradation after meiosis resumption.

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
Poly(A)-binding proteins (PABPs) play roles in mRNA maturation, translational activity, and decay. The functions of PABPs, especially PABPN1 and PABPC1, in somatic cells have been well-studied. However, little is known about the roles of PABPs in oocytes because of the unique mechanisms of mRNA metabolism in oocytes. This study focused on PABPN1L and generated Pabpn1l knockout (KO) mice using the CRISPR/Cas9 system. After mating tests, we found that Pabpn1l KO females were infertile due to the failure of the embryos to develop to the 4-cell stage. RNA-seq analysis revealed aberrant mRNA persistence in Pabpn1l KO-MII oocytes, which indicates impaired mRNA degradation during the germinal vesicle (GV) to MII transition. We also revealed that the exogenous expression of Pabpn1l mRNA in KO-GV oocytes recovered defects of embryonic development. PABPN1L is partly indispensable for female fertility in mice, owing to its necessity for embryonic development, which is supported by mRNA degradation during GV to MII maturation.
