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

Recent studies point to a pivotal role of Polycomb repressive complex 2 (PRC2) in stem cell function and cancer. Loss-of-function approaches targeting individual PRC2 subunits have, however, generated findings that are difficult to reconcile. Here, we prevent assembly of both Ezh1- and Ezh2-containing PRC2 complexes by conditional deletion of Eed, a core subunit, and assess hematopoiesis. We find that deletion of Eed exhausts adult bone marrow hematopoietic stem cells (HSCs), although fetal liver HSCs are produced in normal numbers. Eed-null neonatal HSCs express HSC signature genes but are defective in maintenance and differentiation. Comparative gene expression profiling revealed that neonatal and adult HSCs lacking Eed upregulated gene sets of conflicting pathways. Deletion of Cdkn2a, a PRC2 target gene, in Eed-null mice enhances hematopoietic stem/progenitor cell (HSPC) survival but fails to restore HSC functions. Taken together, our findings define developmental-stage-specific requirements for canonical PRC2 complexes in normal HSC function.
