Argonaute2 and LaminB modulate gene expression by controlling chromatin topology

Drosophila Argonaute2 (AGO2) has been shown to regulate expression of certain loci in an RNA interference (RNAi)-independent manner, but its genome-wide function on chromatin remains unknown. Here, we identified the nuclear scaffolding protein LaminB as a novel interactor of AGO2. When either AGO2 or LaminB are depleted in Kc cells, similar transcription changes are observed genome-wide. In par...

Chromatin loops, gene positioning, and gene expression

Technological developments and intense research over the last years have led to a better understanding of the 3D structure of the genome and its influence on genome function inside the cell nucleus. We will summarize topological studies performed on four model gene loci: the α- and β-globin gene loci, the antigen receptor loci, the imprinted H19-Igf2 locus and the Hox gene clusters. Collectivel...

HMGN proteins modulate chromatin regulatory sites and gene expression during activation of naïve B cells

The activation of naïve B lymphocyte involves rapid and major changes in chromatin organization and gene expression; however, the complete repertoire of nuclear factors affecting these genomic changes is not known. We report that HMGN proteins, which bind to nucleosomes and affect chromatin structure and function, co-localize with, and maintain the intensity of DNase I hypersensitive sites geno...

How Do Y-Chromosomes Modulate Genome-Wide Epigenetic States: Genome Folding, Chromatin Sinks, and Gene Expression

The Y chromosomes of Drosophila melanogaster and D. simulans contain only a handful of protein-coding genes, which are related to sperm mobility and reproductive fitness. Despite low or absent protein coding polymorphism, the Drosophila Y chromosome has been associated with natural phenotypic variation, including variation in the expression of hundreds to thousands of genes located on autosomes...

Epigenome comparisons reveal linkage between gene expression and postnatal remodeling of chromatin domain topology

Substantial evidence has accumulated linking epigenome change to alterations in stem cell function during postnatal development and aging. Yet much remains to be learned about causal relationships, and large gaps remain in our understanding of epigenome-transcriptome interactions. Here we investigate structural features of large histone H3K27me3-enriched regions in human stem cell-like monocyte...
