The elusive role of mitotic bookmarking in transcriptional regulation: Insights from Sox2.

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 ability of some transcription factors to remain bound to specific genes on condensed mitotic chromosomes has been suggested to play a role in their rapid transcriptional reactivation upon mitotic exit. We have recently shown that SOX2 and OCT4 remain associated to mitotic chromosomes, and that depletion of SOX2 at the mitosis-G1 (M-G1) transition impairs its ability to maintain pluripotency and drive neuroectodermal commitment. Here we report on the role of SOX2 at the M-G1 transition in regulating transcriptional activity of embryonic stem cells. Using single cell time-lapse analysis of reporter constructs for STAT3 and SOX2/OCT4 activity, we show that SOX2/OCT4 do not lead to more rapid transcriptional reactivation in G1 than STAT3, a transcription factor that is excluded from mitotic chromosomes. We also report that only few endogenous target genes show decreased pre-mRNA levels after mitotic exit or in other cell cycle phases in the absence of SOX2 at the M-G1 transition. This suggests that bookmarked SOX2 target genes are not differently regulated than non-bookmarked target genes, and we discuss an alternative hypothesis on how mitotic bookmarking by SOX2 and other sequence-specific transcription factors could be involved in transcriptional regulation.
