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

Epigenetic mechanisms underlying somatic reprogramming have been extensively studied, but little is known about the nuclear architecture of pluripotent stem cells (PSCs). Using circular chromosome conformation capture with high-throughput sequencing (4C-seq) and fluorescence in situ hybridization (FISH), we identified chromosomal regions that colocalize frequently with the Oct4 locus in PSCs. These PSC-specific long-range interactions are established prior to transcriptional activation of endogenous Oct4 during reprogramming to induced PSCs and are facilitated by Klf4-mediated recruitment of cohesin. Depletion of Klf4 leads to unloading of cohesin at the Oct4 enhancer and disrupts long-range interactions prior to loss of Oct4 transcription and subsequent PSC differentiation, suggesting a causative role for Klf4 in facilitating long-range interactions independent of its transcriptional activity. Taken together, our results delineate the basic nuclear organization at the Oct4 locus in PSCs and suggest a functional role for Klf4-mediated higher-order chromatin structure in maintaining and inducing pluripotency.
