Oocyte development encompasses a series of highly orchestrated stages, beginning with the activation of primordial follicles and culminating in the formation of a mature, fertilisation-competent egg.

Chromatin in plants is a dynamic assembly of DNA and associated proteins whose organisation and chemical modifications underpin the precise control of gene activity. Nucleosomes—the basic structural ...

The serine 31 (Ser31) phosphorylation modification (H3.3S31ph) in the N-terminal tail of the histone variant H3.3 can transform H3.3 nucleosomes from a stable state to a dynamically activated ...

Gene expression is controlled, in part, by the interactions between genes and regulatory elements located along the genome. Those interactions depend on the ability of chromatin, a mix of DNA and ...

Gene expression is controlled, in part, by the interactions between genes and regulatory elements located along the genome. Those interactions depend on the ability of chromatin - a mix of DNA and ...

DNA inside the nucleus is not packed as a rigid regular fiber-linker histone H1 dynamically binds and loosely "glues" nucleosomes together, creating a dynamic, fluid organization that can still ...

Certain epigenetic modifications can directly control how genetic material is packed in the nucleus, RIKEN researchers have shown. This has important implications for our understanding of how genes ...

Aging is accompanied by widespread epigenetic reprogramming, including the loss of heterochromatin and altered chromatin-associated processes. These changes compromise transcriptional precision and ...
