Cells differentiate and progress through development guided by a dynamic chromatin
landscape that mediates gene expression programmes. During development, mammalian …

BACKGROUND Multicellular organisms depend on the precise orchestration of gene
expression to direct embryonic development and to maintain tissue homeostasis through …

Polycomb group (PcG) proteins are epigenetic regulators of transcription that have key roles
in stem-cell identity, differentiation and disease. Mechanistically, they function within …

Chromatin modification by Polycomb proteins provides an essential strategy for gene
silencing in higher eukaryotes. Polycomb repressive complexes (PRCs) silence key …

Post-translational modifications of histones by protein methyltransferases (PMTs) and
histone demethylases (KDMs) play an important role in the regulation of gene expression …

The chromatin environment is essential for the correct specification and preservation of cell
identity through modulation and maintenance of transcription patterns. Many chromatin …
