Establishment and maintenance of heritable chromatin structure during early Drosophila embryogenesis
During embryogenesis, the initial chromatin state is established during a period of rapid proliferative activity. We have measured with 3-min time resolution how heritable patterns of chromatin structure are initially established and maintained during ...

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

Chromatin Structure in Telomere Dynamics [PDF]
The establishment of a specific nucleoprotein structure, the telomere, is required to ensure the protection of chromosome ends from being recognized as DNA damage sites. Telomere shortening below a critical length triggers a DNA damage response that leads to replicative senescence.

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.

NoRC, a novel chromatin remodeling complex involved in ribosomal RNA gene silencing [PDF]
Regulation of gene expression takes place in the nucleus in a highly structured and condensed nucleoprotein environment, called chromatin (Felsenfeld and Groudine, 2003; Khorasanizadeh, 2004; Vaquero et al., 2003).

THE STRUCTURE AND FUNCTION OF CHROMATIN AND CHROMOSOMES [PDF]
1. Background One of the striking features of the eukaryotic nucleus is that chromosomes adopt preferred conformations that vary across different tissues and developmental stages. Many lines of evidence suggest the functional significance of genome architecture, including the existence of chromosomes territories [1], the correlation between radial ...

The language of chromatin modification in human cancers
The genetic information of human cells is stored in the context of chromatin, which is subjected to DNA methylation and various histone modifications.

Evolutionary dynamics of chromatin structure and duplicate gene expression in diploid and allopolyploid cotton [PDF]
Polyploidy is a prominent mechanism of plant speciation and adaptation, yet the mechanistic understandings of duplicated gene regulation remain elusive. Chromatin structure dynamics are suggested to govern gene regulatory control.

Histone methylation by PRC2 is inhibited by active chromatin marks [PDF]
Chromatin modifiers serve as regulatory switches that control the cell cycle, maintain pluripotency and drive differentiation and development. Positive feedback mechanisms help to pass on transcriptional information from one generation of cells to the ...

Kinetochore function depends on H4K20 monomethylation in centromeric nucleosomes but the underlying mechanism is unclear. Here, the authors provide evidence that the centromere-specific nucleosome subunit CENP-A facilitates H4K20 methylation by enabling ...
