The Dynamic Chromatin Architecture of the Regenerating Liver [PDF]

Cellular and Molecular Gastroenterology and Hepatology, 2019
ABSTRACT Background & Aims The adult liver is the main detoxification organ and is routinely exposed to environmental insults but retains the ability to restore its mass and function upon tissue damage.

Chromatin Architecture Reconstruction [PDF]

Biophysical Journal, 2012
Three-dimensional genomic architecture is increasingly being found to play an important role in the regulation of gene expression through direct physical interactions of distant genomic sites. Conformation Capture Techniques (CCTs) attempt to resolve the conformation of a genetic sequence or entire genome by measuring mean interaction frequencies ...

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,

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 ...

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.

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.

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

Chromatin architecture reprogramming reveals novel epigenetic dependencies in breast cancer. [PDF]

Genes Dev
Chromatin architecture plays a key role in development and cancer, yet most studies lack mechanistic depth due to widespread epigenomic remodeling. To address this, we tracked chromatin structure dynamics during the progression of endocrine resistance in

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 ...

Genetic Architecture of Transcription and Chromatin Regulation [PDF]

Genomics & Informatics, 2015
DNA microarray and next-generation sequencing provide data that can be used for the genetic analysis of multiple quantitative traits such as gene expression levels, transcription factor binding profiles, and epigenetic signatures. In particular, chromatin opening is tightly coupled with gene transcription.
