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

Polycomb repressive complex 2 (PRC2) is an essential regulator of cell physiology. Although there have been numerous studies on PRC2 function in somatic tissue development and stem cell control, these have focused on the loss of a single PRC2 subunit. Recent studies, however, have shown that PRC2 subunits may function independently of the PRC2 complex. To investigate the function of PRC2 in the control of skin development, we generated and analyzed three conditional knockout mouse lines, in which the essential PRC2 subunits embryonic ectoderm development (EED), suppressor of zeste 12 homolog (Suz12), and enhancer of zeste homologs 1 and 2 (Ezh1/2) are conditionally ablated in the embryonic epidermal progenitors that give rise to the epidermis, hair follicles, and Merkel cells. Our studies showed that the observed loss-of-function phenotypes are shared between the three knockouts, indicating that in the skin epithelium, EED, Suz12, and Ezh1/2 function largely as subunits of the PRC2 complex. Interestingly, the absence of PRC2 results in dramatically different phenotypes across the different skin lineages: premature acquisition of a functional epidermal barrier, formation of ectopic Merkel cells, and defective postnatal development of hair follicles. The strikingly different roles of PRC2 in the formation of three lineages exemplify the complex outcomes that the lack of PRC2 can have in a somatic stem cell system.
