Telomeric chromatin structure

open access: yesCurrent Opinion in Structural Biology, 2022
Eukaryotic DNA is packaged into nucleosomes, which further condenses into chromosomes. The telomeres, which form the protective end-capping of chromosomes, play a pivotal role in ageing and cancer. Recently, significant advances have been made in understanding the nucleosomal and telomeric chromatin structure at the molecular level. In addition, recent

Chromatin structure in cancer

open access: yesBMC Molecular and Cell Biology, 2022
In the past decade, we have seen the emergence of sequence-based methods to understand chromosome organization. With the confluence of in situ approaches to capture information on looping, topological domains, and larger chromatin compartments ...

Live-cell visualisation of chromatin for the study of radiation-induced chromosome aberrations [PDF]

open access: yes, 2011
This thesis was submitted for the degree of Master of Philosophy and awarded by Brunel University.Chromosomes can be visualised during the metaphase stage of the cell cycle however, there are various limitations associated with the visualisation of ...

The Structure of Chromatin [PDF]

open access: yesProceedings of the National Academy of Sciences, 1971
The DNA in chromatin of isolated thymus nuclei, and in two different preparations of deoxyribonucleoprotein extracted from chromatin, has been digested with DNase. By variation of the time of reaction and the concentration of enzyme, and by comparison of the action of the enzyme on (protein-free) DNA with its action on DNA complexed with protein in ...

Function of the upstream activating factor in chromatin structure organization and transcriptional regulation at the yeast ribosomal DNA [PDF]

open access: yes, 2010
Chromatin is the template of all processes involved in DNA metabolism in the eukaryotic cell. Accordingly, chromatin is a dynamic structure which changes in its composition and posttranslational modification correlating with the functional state of a ...

Repressive and non-repressive chromatin at native telomeres in Saccharomyces cerevisiae [PDF]

open access: yes, 2009
Background In Saccharomyces cerevisiae genes that are located close to a telomere can become transcriptionally repressed by an epigenetic process known as telomere position effect.

Perturbation of chromatin structure globally affects localization and recruitment of splicing factors [PDF]

open access: yes, 2012
Chromatin structure is an important factor in the functional coupling between transcription and mRNA processing, not only by regulating alternative splicing events, but also by contributing to exon recognition during constitutive splicing.

Proteomic interrogation of human chromatin. [PDF]

open access: yes, 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,

Dynamic chromatin: concerted nucleosome remodelling and acetylation [PDF]

open access: yes, 2005
The flexibility of chromatin that enables translation of environmental cues into changes in genome utilisation, relies on a battery of enzymes able to modulate chromatin structure in a highly targeted and regulated manner.

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

open access: yes, 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.
