Extended chromatin fibers and chromatin organization

Biotechnic & Histochemistry, 2010
Studies of chromatin extensibility have revealed the flow of chromatin and DNA from cell nuclei and chromosomes in response to gravity or mechanical stretch following lysis by hypertonic saline and detergent solutions. Since this phenomenon was first reported, the technical methods by which extended chromatin fibers (ECFs) may be analyzed have been ...

Chromatin and signaling

Current Opinion in Cell Biology, 2013
Signaling involves the coordinated action of multiple molecules including stimuli, receptors and enzymes part of which interact with the transcriptional machinery and target chromatin. Signaling systems regulate the cell events responsible for survival, development and homeostasis.

Chromatin replication

BioEssays, 1992
AbstractJust as the faithful replication of DNA is an essential process for the cell, chromatin structures of active and inactive genes have to be copied accurately. Under certain circumstances, however, the activity pattern has to be changed in specific ways.

Chromatin Immunoprecipitation

Cold Spring Harbor Protocols, 2020
Chromatin immunoprecipitation, commonly referred to as ChIP, is a powerful technique for the evaluation of in vivo interactions of proteins with specific regions of genomic DNA. Formaldehyde is used in this technique to cross-link proteins to DNA in vivo, followed by the extraction of chromatin from cross-linked cells and tissues.

The other chromatin

Chromosoma, 2001
Current understanding of heterochromatin, thanks to molecular data, focuses on its performing several functions in evolution and development. Heterochromatin shows characteristic distribution patterns in karyotypes and contributes to the broad scattering of genome sizes through biological taxa.

Chromatin

Nature, 1978
The approximate shape of the chromatin subunit called the nucleosome is now known, but its internal architecture is not well understood. Recent studies reveal details of the organisation of DNA within the nucleosome, and show that the arginine-rich histones are essential to DNA folding.

Reprogramming chromatin

Critical Reviews in Biochemistry and Molecular Biology, 2012
Cellular reprogramming involves the artificial dedifferentiation of somatic cells to a pluripotent state. When affected by overexpressing specific transcription factors, the process is highly inefficient, as only 0.1-1% of cells typically undergo the transformation.

Transcribed chromatin

Trends in Biochemical Sciences, 1992
In eukaryotes, DNA that is transcribed is packaged first into nucleosomes and then into chromatin fibres. How does transcription proceed through chromatin? Studies of transcription through nucleosomes in vitro suggest that the intracellular environment may provide factors which alleviate the inhibitory effect that nucleosomes have on transcription ...

Chromatin remodelling

Current Opinion in Plant Biology, 2001
Epigenetic mechanisms are heritable traits that are mediated by changes in a genetic locus that do not involve a modification at the nucleotide level. As eukaryotic DNA is organised in chromatin units, epigenetic modifications can be mediated by chromatin remodelling.
