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 mechanistic role of trisomy 8 in the development of myelodysplastic syndrome (MDS) remains poorly defined. Here, we generated a trisomy 8 mouse model by transferring a human chromosome 8 into murine embryonic stem cells and prospectively examined the effects on hematopoietic stem cells (HSC) by trisomy 8. The expression of inflammatory genes was enhanced, and hematopoietic programs mediated by transcription factors and polycomb repressive complex 2 (PRC2) were dysregulated in trisomy 8 HSC, which impaired their self-renewal and balanced differentiation. Trisomy 8 HSC altered the chromatin accessibility and conformations and activated Y chromosome genes, such as Uty/Kdm6c epigenetic modifier, which is known to demethylate histone H3K27me3 modification. The Uty gene facilitated the activation of PRC2-target and Runx1-target genes in leukemogenesis and drove the proliferation of human trisomy 8 leukemic cells. Since the RUNX1 gene is frequently mutated in patients with trisomy 8 MDS, its deletion attenuated the enhanced expression of inflammatory genes and mitigated the impaired self-renewal of trisomy 8 HSC in mice. Our findings reveal that trisomy 8 altered the transcriptional programs and chromatin conformations in HSC and drove a pre-malignant state through activating the expression of Uty, suggesting a route for the development of trisomy 8 MDS.
