GenomicsGenome-wide analysis of H3.3 dissociation in mouse embryonic stem cells
Using Tet-inhibited expression of epitope-tagged H3.3 combined with ChIP-Seq we undertook genome-wide measurements of H3.3 dissociation rates across the ESC genome and examined the relationship between H3.3-nucleosome turnover and ESC-specific transcription factors, chromatin modifiers and epigeneti...

TranscriptomicsHistone H3.3 and its proteolytically processed form drive a cellular senescence program
In this study, we have uncovered novel proteolytic processing of the histone H3 tail in senescence models in primary fibroblasts and melanocytes. Cleavage of H3 tail occurs at two distinct residues and is mediated by Cathepsin L. We show that variant H3.3 is preferentially cleaved, and that cleaved ...

GenomicsGenome-wide incorporation dynamics reveal distinct categories of turnover for the histone variant H3.3
We developed a system to study the DNA replication-independent turnover nucleosomes containing the histone variant H3.3 in mammalian cells. By measuring the genome-wide incorporation of H3.3 at different time points following epitope-tagged H3.3 expression, we find three categories of H3.3-nucleosom...

TranscriptomicsHistone variant H3.3 is an essential maternal factor for oocyte reprogramming
Mature oocyte cytoplasm can reprogram somatic cell nuclei to the pluripotent state through a series of sequential events including protein exchange between the donor nucleus and ooplasm, chromatin remodeling, and pluripotency gene reactivation. Maternal factors that are responsible for this reprogra...

GenomicsDistinct factors control histone variant H3.3 localization at specific genomic regions
The incorporation of histone H3 variants has been implicated in the epigenetic memory of cellular state. Using genome editing with zinc finger nucleases to tag endogenous H3.3, we report genome-wide profiles of H3 variants in mammalian embryonic stem (ES) cells and neuronal precursor cells. Genome-w...

GenomicsHistone H3.3 regulates dynamic chromatin states during spermatogenesis
We used H3f3b-/- testes to analyze the impact of H3f3b derived H3.3 on spermatogenesis. Analysis of Histone H3 (Lys 4) tri-methylation in H3f3b WT/WT and H3f3b -/- testes tissue.

TranscriptomicsHistone H1 binding is restricted by histone variant H3.3 (Expression)
Linker histones are involved in the formation of higher-order chromatin structure. Although linker histones have been implicated in the regulation of specific genes, it still remains unclear what their principal binding determinants are and how their repressive function in vitro can be reconciled wi...
