Purpose: We investigated the existence, nature and significance of mitotic bookmarking of Klf4, Oct4, Sox2 (KOS) and H3K27ac in mouse ESCs. Methods: DNA-binding/epigenetic profiles of KOS and H3K27ac on asynchronous and mitotic chromatin were generated by deep sequencing following chromatin immunoprecipitation, in replicates. Results: KOS and H3K27ac are largely maintained on mitotic chromatin. KOS bookmark critical stem cell regulatory elements during mitosis. H3K27 acetylation during mitosis i...

How this grade was computed

The insufficient grade is a transparent weighted average. Each metric below scored from 0–100% against the published ChIP-seq thresholds, weighted by its importance; nothing is hidden or subjective.

Scientific quality

Based on hands-on reproduction of the papers that use this dataset. A reproducible paper that stands on this data is positive evidence; a flagged one is a prompt to look closer — never a verdict on the dataset itself without the evidence.
