The epigenetic modifications and the anterior to posterior characterization of meiotic entry during mouse oogenesis.

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
The meiotic initiation of mammalian oogonia is a critical step during the development of primordial germ cells (PGCs) to mature oocytes. In this study, a systematic investigation of epigenetic modifications and DAZL gene expression during oogonia meiotic entry were performed. We found that the expression of DAZL was epigenetically regulated by DNA methylation of CpG islands within its promoter region. During meiotic entry, a continuously increasing level of 5hmC, a stable epigenetic marker usually associated with the activation of gene expression, was observed from 11.5 to 16.5 dpc (days post coitum). Meanwhile trimethylation of lysine 27 on histone3 (H3K27me3), usually associated with repression of gene expression, had a sustainable increase from 12.5 to 16.5 dpc. Finally, by equally dividing the ovaries into three regions representing the anterior, the middle, and the posterior of the ovary and performing immunofluorescence and qRT-PCR on the individual regions, we provided further evidences that the meiotic entry and progression of female germ cells is in an anterior to posterior pattern.
