Title Stem cell regulatory elements remain bookmarked by selected transcription factors and epigenetic marks during mitosis
Organism Mus musculus
Experiment type Genome binding/occupancy profiling by high throughput sequencing
Summary 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 is highly retained on promoters of cell cycle and homeostasis related genes and enhancers of genes important for any given cell identity.
Conclusions: The extensive mitotic occupancy that we observed is in agreement with a recent study that proposes that TF retention on mitotic chromatin may be a much broader phenomenon than previously appreciated.

Overall design Short read signle-end ChIP-seq in V6.5 murine ESC for Klf4 (3 asynchronous and mitotic replicates, respectively ), Oct4 (1 asynchronous replicate with the additional G1 sample of GSE78073, and 2 mitotic replicates with the additional mitotic sample of GSE78073), Sox2(1 asynchronous replicate with the additional asynchronous sample of GSE44288 , and 2 mitotic replicates), H3K27ac (2 asynchronous and mitotic replicates, respectively) and whole cell extract input DNA (7 runs). Mitotic arrest was done as follows: 80-90% confluent mouse ESCs were split 1:3 on gelatinized plates the day before synchronization. Nocodazole at 100ug/ml was added in the medium for 7hr prior to collection by mitotic shake-off.
