EZH2 modulates mRNA splicing and exerts part of its oncogenic function through repression of splicing factors in CML.

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.
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 polycomb protein EZH2 is up-regulated in Chronic Myeloid Leukaemia (CML) and associated with transcriptional reprogramming. Here we tested whether EZH2 might also act as a modulator of the mRNA splicing landscape to elicit its oncogenic function in CML. We treated CML cell lines with EZH2 inhibitors and detected differential splicing of several hundreds of events, potentially caused by the transcriptional regulation of splicing factors. Amongst those genes, CELF2 was identified as a candidate to mediate part of the EZH2 inhibitor induced phenotype. Upon over-expression, we observed (1) reduced cell growth, viability, and colony formation of CML cell lines, (2) a change in the splicing landscape, partially overlapping with EZH2 mediated changes, (3) the down-regulation of MYC signalling. Importantly, these findings were successfully validated in a cohort of CML patient samples, confirming the role of CELF2 as EZH2-regulated tumour-suppressor, contributing to the severe splicing de-regulation present in CML. Based on this we propose that EZH2 exerts part of its oncogenic function in CML through the transcriptional repression of splicing factors. Finally, analysis of publicly available datasets suggests that splicing modulation by EZH2 might not be restricted to CML.
