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 transcription factor Meis1 is expressed preferentially in hematopoietic stem cells (HSCs) and overexpressed in certain leukemias. However, the functions of Meis1 in hematopoiesis remain largely unknown. In the present study, we found that Meis1 is required for the maintenance of hematopoiesis under stress and over the long term, whereas steady-state hematopoiesis was sustained in the absence of Meis1 in inducible knock-out mice. BM cells of Meis1-deficient mice showed reduced colony formation and contained significantly fewer numbers of long-term HSCs, which exhibited loss of quiescence. Further, we found that Meis1 deletion led to the accumulation of reactive oxygen species in HSCs and decreased expression of genes implicated in hypoxia response. Finally, reactive oxygen species scavenging by N-acetyl cysteine or stabilization of hypoxia signaling by knockdown of the von-Hippel-Lindau (VHL) protein led to reversal of the effects of Meis1 deletion. The results of the present study demonstrate that Meis1 protects and preserves HSCs by restricting oxidative metabolism.
