Analysis of telomere maintenance in artemis defective human cell lines [PDF]

, 2009
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Telomeres are physical ends of chromosomes consisting of (TTAGGG)n DNA sequence and a specialized set of proteins that protect chromosomal ends from ...

Retrotransposons and Telomeres

Biochemistry (Moscow), 2023
Abstract Transposable elements (TEs) comprise a significant part of eukaryotic genomes being a major source of genome instability and mutagenesis. Cellular defense systems suppress the TE expansion at all stages of their life cycle.

A ‘higher order’ of telomere regulation: telomere heterochromatin and telomeric RNAs [PDF]

The EMBO Journal, 2009
Protection of chromosome ends from DNA repair and degradation activities is mediated by specialized protein complexes bound to telomere repeats. Recently, it has become apparent that epigenetic regulation of the telomeric chromatin template critically impacts on telomere function and telomere-length homeostasis from yeast to man.

Telomeres and Telomere Length: A General Overview [PDF]

Cancers, 2020
Telomeres are highly conserved tandem nucleotide repeats that include proximal double-stranded and distal single-stranded regions that in complex with shelterin proteins afford protection at chromosomal ends to maintain genomic integrity. Due to the inherent limitations of DNA replication and telomerase suppression in most somatic cells, telomeres ...

The Tail of the Telomere [PDF]

Journal of the American Chemical Society, 2008
The structure of a higher-order G-quadruplex structure for human telomeric DNA is presented. The structure was determined by a novel integrated approach in which molecular dynamics simulations were used to produce a stable structure, from which specific experimentally accessible properties were predicted.

Telomeric RNAs are essential to maintain telomeres [PDF]

Nature Communications, 2016
AbstractTelomeres are transcribed generating long non-coding RNAs known as TERRA. Deciphering the role of TERRA has been one of the unsolved issues of telomere biology in the past decade. This has been, in part, due to lack of knowledge on the TERRA loci, thus preventing functional genetic studies. Here, we describe that long non-coding RNAs with TERRA

Telomere lengths in human oocytes, cleavage stage embryos and blastocysts [PDF]

, 2010
Telomeres are repeated sequences that protect the ends of chromosomes and harbour DNA-repair proteins. Telomeres shorten during each cell division in the absence of telomerase.

The human telomeric proteome during telomere replication [PDF]

Nucleic Acids Research, 2020
Abstract Telomere shortening can cause detrimental diseases and contribute to aging. It occurs due to the end replication problem in cells lacking telomerase. Furthermore, recent studies revealed that telomere shortening can be attributed to difficulties of the semi-conservative DNA replication machinery to replicate the bulk of ...

Is telomere length a biomarker for aging: cross-sectional evidence from the west of Scotland? [PDF]

, 2012
Background <p> The search for biomarkers of aging (BoAs) has been largely unsuccessful to-date and there is widespread skepticism about the prospects of finding any that satisfy the criteria developed by the American Federation of Aging Research ...
