Chromatin Organisation and Genome Architecture
Dynamic yet functionally stable organization of cellular processes is a crucial feature of biological systems, allowing them to respond to external stimuli and survive. The eukaryotic nucleus represents a complex subcellular organelle where DNA and RNA metabolism occurs through spatio-temporally organized processes that change dynamically during the ...

Chromatin Architecture Reconstruction [PDF]
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 ...

Effects of DNA supercoiling on chromatin architecture [PDF]
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 ...

Proteomic interrogation of human chromatin. [PDF]
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]
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]
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]
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.

Chromatin architecture defines the glucocorticoid response [PDF]
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]
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.

Regulation of Chromatin Architecture by Transcription Factor Binding
Abstract Transcription factors (TF) bind to chromatin and regulate the expression of genes. The pair Myc:Max binds to E-box regulatory DNA elements throughout the genome, controlling transcription of a large group of specific genes. We introduce an implicit modeling protocol for Myc:Max binding to mesoscale chromatin fibers to determine
