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

Multiple levels of control are in play to regulate pluripotency and differentiation in human embryonic stem cells (hESCs). At the transcriptional level, the core factors OCT4, NANOG and SOX2 form a positive autoregulatory loop that is pivotal for maintaining the undifferentiated state. At the post-transcriptional level, microRNAs (miRNAs) belonging to the miR-302 family are emerging as key players in the control of proliferation and cell fate determination during differentiation. Here, we show that the transcriptional factors OCT4 and NR2F2 (COUP-TFII) and the miRNA miR-302 are linked in a regulatory circuitry that critically regulate both pluripotency and differentiation in hESCs. In the undifferentiated state, both OCT4 and the OCT4-induced miR-302 directly repress NR2F2 at the transcriptional and post-transcriptional level, respectively. Conversely, NR2F2 directly inhibits OCT4 during differentiation, triggering a positive feedback loop for its own expression. In addition, we show that regulation of NR2F2 activity itself relies on alternative splicing and transcriptional start site choice to generate a full-length transcriptionally active isoform and shorter variants, which enhance the activity of the long isoform. During hESC differentiation, NR2F2 is first detected at the earliest steps of neural induction and thus is among the earliest human embryonic neural markers. Finally, our functional analysis points to a crucial role for NR2F2 in the activation of neural genes during early differentiation in humans. These findings introduce a new molecular player in the context of early embryonic stem cell state and cell fate determination in humans.
