Expression Profiling and Function Analysis Identified New Cumulus Cells-Expressed Genes and miRNAs Predictive of Oocyte Developmental Potential.

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
Although prior studies have identified cumulus cells (CCs)-expressed genes and miRNAs that regulate cumulus expansion and/or CC apoptosis and may serve as markers for selecting competent oocytes and embryos, there remains an urgent need to identify CCs-expressed genes and miRNAs whose expression levels are directly correlated with oocyte developmental potential (DP). In this study, we first established CC models from mouse cumulus-oocyte complexes (COCs) that exhibited significantly different DP following in vitro or in vivo maturation. Subsequently, we performed mRNA/miRNA sequencing and functional analyses using these in vitro and in vivo CC models. We identified and validated Spp1, Fn1, Sdc1, and Ngf as DP-beneficial genes; Fos and Jun as DP-detrimental genes; and miR-7686-5p, miR-133a-3p, novel-miR-239, novel-miR-193, and miR-339-5p as DP-detrimental miRNAs. Finally, by employing a well-in-well activation/embryo culture system that enables tracking the COC origin of CCs and embryos, we further validated Spp1 and Ngf as DP-beneficial genes, Jun as the DP-detrimental gene, and miR-7686-5p, novel-miR-239, and miR-339-5p as DP-detrimental miRNAs. In conclusion, we identified and validated new sets of CCs-expressed genes and miRNAs whose expression levels were directly correlated with oocyte DP. These newly identified genes and miRNAs may serve as potential biomarkers for selecting competent oocytes and embryos.
