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

The Additional sex combs like 1 (Asxl1) gene is 1 of 3 mammalian homologs of the Additional sex combs (Asx) gene of Drosophila. Asx is unusual because it is required to maintain both activation and silencing of Hox genes in flies and mice. Asxl proteins are characterized by an amino terminal homology domain, by interaction domains for nuclear receptors, and by a C-terminal plant homeodomain protein-protein interaction domain. A recent study of patients with myelodysplastic syndrome (MDS) and chronic myelomonocytic leukemia (CMML) revealed a high incidence of truncation mutations that would delete the PHD domain of ASXL1. Here, we show that Asxl1 is expressed in all hematopoietic cell fractions analyzed. Asxl1 knockout mice exhibit defects in frequency of differentiation of lymphoid and myeloid progenitors, but not in multipotent progenitors. We do not detect effects on hematopoietic stem cells, or in peripheral blood. Notably, we do not detect severe myelodysplastic phenotypes or leukemia in this loss-of-function model. We conclude that Asxl1 is needed for normal hematopoiesis. The mild phenotypes observed may be because other Asxl genes have redundant function with Asxl1, or alternatively, MDS or oncogenic phenotypes may result from gain-of-function Asxl mutations caused by genomic amplification, gene fusion, or truncation of Asxl1.
