Telomeric RNAs are essential to maintain telomeres [PDF]

open access: yesNature Communications, 2016
The telomeric long-non coding RNA, TERRA, has been proposed in the past to modulate different telomeric functions based on in vitrostudies. Here the authors show, using a genetic deletion approach, that TERRA is transcribed from the 20q subtelomere and ...

Telomeres

open access: yesCurrent Opinion in Cell Biology, 1991
Telomeres are essential for chromosome stability and replication. Maintaining a balance between telomere shortening and lengthening is essential for cell viability. Recent work on telomeres from yeast, Drosophila and mammals, and on telomerase has provided insight into the mechanisms of both the shortening and lengthening processes.

Retrotransposons and Telomeres

open access: yesBiochemistry (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]

open access: yesThe 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]

open access: yesCancers, 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]

open access: yesJournal 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.

Telomeres in Evolution and Development from Biosemiotic Perspective [PDF]

open access: yes, 2007
Telomeres identify natural chromosome ends being different from broken DNA through differences in their "molecular syntax" (M.Eigen) which determines the functions of reverse transcriptase and its integrated RNA template, telomerase.
