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

To reveal the extent of domain-wide epigenetic features at imprinted gene clusters, we performed a high-resolution allele-specific chromatin analysis of over 100 megabases along the maternally or paternally duplicated distal chromosome 7 (Chr7) and Chr15 in mouse embryo fibroblasts (MEFs). We found that reciprocal allele-specific features are limited to imprinted genes and their differentially methylated regions (DMRs), whereas broad local enrichment of H3K27me3 (BLOC) is a domain-wide feature at imprinted clusters. We uncovered novel allele-specific features of BLOCs. A maternally biased BLOC was found along the H19-Igf2 domain. A paternal allele-specific gap was found along Kcnq1ot1, interrupting a biallelic BLOC in the Kcnq1-Cdkn1c domain. We report novel allele-specific chromatin marks at the Peg13 and Slc38a4 DMRs, Cdkn1c upstream region, and Inpp5f_v2 DMR and paternal allele-specific CTCF binding at the Peg13 DMR. Additionally, we derived an imprinted gene predictor algorithm based on our allele-specific chromatin mapping data. The binary predictor H3K9ac and CTCF or H3K4me3 in one allele and H3K9me3 in the reciprocal allele, using a sliding-window approach, recognized with precision the parental allele specificity of known imprinted genes, H19, Igf2, Igf2as, Cdkn1c, Kcnq1ot1, and Inpp5f_v2 on Chr7 and Peg13 and Slc38a4 on Chr15. Chromatin features, therefore, can unequivocally identify genes with imprinted expression.
