More than 80 years ago, the first Polycomb-related phenotype was identified in Drosophila
melanogaster. Later, a group of diverse genes collectively called Polycomb group (PcG) …

The polycomb repressive complex 2 (PRC2) is a chromatin-associated methyltransferase
catalyzing mono-, di-, and trimethylation of lysine 27 on histone H3 (H3K27). This activity is …

Addition of chemical tags on the DNA and modification of histone proteins impart a distinct
feature on chromatin architecture. With the advancement in scientific research, the key …

Histones are subject to a vast array of posttranslational modifications including acetylation,
methylation, phosphorylation, and ubiquitylation. The writers of these modifications play …

Methylation of cytosine in CpG dinucleotides and histone lysine and arginine residues is a
chromatin modification that critically contributes to the regulation of genome integrity …

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

Chromatin profiling at locus resolution uncovers gene regulatory features that define cell
types and developmental trajectories, but it remains challenging to map and compare …

The role of long noncoding RNA (lncRNA) in adult hearts is unknown; also unclear is how
lncRNA modulates nucleosome remodelling. An estimated 70% of mouse genes undergo …

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

The Polycomb repressive system is an essential chromatin-based regulator of gene
expression. Despite being extensively studied, how the Polycomb system selects its target …
