Distinct associations of pioneer factor Ascl1-E12a with nucleosomes drive changes in cell fate.

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
Understanding how pioneer transcription factors target nucleosomal DNA and initiate chromatin accessibility reveals the earliest events in cell fate changes. We integrated structural, biochemical, and genomic approaches to assess how the pioneer factor Ascl1-E12a heterodimer perturbs nucleosomes in vitro and in vivo to induce a neural cell fate. Two Ascl1-E12a heterodimers shift and unwrap 15 bp of nucleosomal DNA in a stepwise manner while eliciting solvent exchanges within the octamer. Nucleosome binding, but not free DNA binding, by Ascl1-E12a is enhanced by two types of associations with the nucleosome that differentially affect the kinetics of DNA unwrapping and shifting. Nucleosome association mutants of Ascl1 perturb chromatin opening on linker histone-compacted nucleosome arrays-independent of nucleosome remodelers-and targeting of closed chromatin in vivo, with consequent deficiencies in cellular reprogramming. Our findings establish that distinct associations with nucleosomes are essential for the pioneer factor Ascl1 to overcome chromatin barriers to reprogram cell fate.
