Proteomic interrogation of human chromatin. [PDF]

, 2011
Chromatin proteins provide a scaffold for DNA packaging and a basis for epigenetic regulation and genomic maintenance. Despite understanding its functional roles, mapping the chromatin proteome (i.e. the "Chromatome") is still a continuing process. Here,

The Adenomatous Polyposis Coli protein contributes to normal compaction of mitotic chromatin [PDF]

, 2012
The tumour suppressor <i>Adenomatous Polyposis Coli</i> (APC) is required for proper mitosis; however, the exact role of APC in mitosis is not understood.

Quantitative analysis of chromatin compaction in living cells using FLIM-FRET [PDF]

, 2009
We present a quantitative Forster resonance energy transfer (FRET)-based assay using multiphoton fluorescence lifetime imaging microscopy (FLIM) to measure chromatin compaction at the scale of nucleosomal arrays in live cells. The assay uses a human cell

Transcriptional gene silencing mutants in "Arabidopsis thaliana" and their impact on nuclear architecture and heterochromatin organization [PDF]

, 2004
The epigenetic regulation of gene expression is defined by covalent modifications of DNA and histone tails as well as by chromatin structure and nuclear architecture.

RNA polymerase II primes Polycomb‐repressed developmental genes throughout terminal neuronal differentiation

Molecular Systems Biology, 2017
Polycomb repression in mouse embryonic stem cells (ESCs) is tightly associated with promoter co‐occupancy of RNA polymerase II (RNAPII) which is thought to prime genes for activation during early development. However, it is unknown whether RNAPII poising

Chromatin architecture defines the glucocorticoid response [PDF]

Molecular and Cellular Endocrinology, 2013
The glucocorticoid receptor (GR) functions to regulate a wide group of physiological processes through hormone inducible interaction with genomic loci and subsequent manipulation of the transcriptional output of target genes. Despite expression in a wide variety of tissues, the GR has diverse roles that are regulated tightly in a cell type specific ...

Identification and validation of transcription factors that regulate chromatin dynamics [PDF]

, 2012
Gene expression has to be tightly regulated during all cellular processes. During embryonic development differentiating cells loose their developmental potential and acquire specific functions by activating lineage-specific genes.

Inferring the physical properties of yeast chromatin through Bayesian analysis of whole nucleus simulations

Genome Biology, 2017
Background The structure and mechanical properties of chromatin impact DNA functions and nuclear architecture but remain poorly understood. In budding yeast, a simple polymer model with minimal sequence-specific constraints and a small number of ...

Chromatin information content landscapes inform transcription factor and DNA interactions

Nature Communications, 2021
Interaction between transcription factors and chromatin is fundamental for genome organization and regulation. Here, the authors use information theory to measure signatures of organized chromatin resulting from transcription factor-chromatin ...

Effects of DNA supercoiling on chromatin architecture [PDF]

Biophysical Reviews, 2016
Disruptions in chromatin structure are necessary for the regulation of eukaryotic genomes, from remodelling of nucleosomes at the base pair level through to large-scale chromatin domains that are hundreds of kilobases in size. RNA polymerase is a powerful motor which, prevented from turning with the tight helical pitch of the DNA, generates over-wound ...
