SARS-CoV-2 causes the pandemic coronavirus disease COVID-19, that is more harmful for elderly people, who show more severe symptoms and are at higher risk of hospitalization and death.

Scheme representing the telomeric elongation process associated with the cell division of pluripotent cells and the generation of animals with hyper-long telomeres. Mouse embryonic stem cells are ...

There is a need regarding cardiovascular disease and heart failure for a therapy that reverses the progression of ventricular dysfunction. Previous findings have shown that cardiomyocytes during ...

The extreme ends of every telomere are not blunt, as the 3’ single-stand overhang comprises 200 nucleotides and loops back with some of the double-stranded telomeric DNA to make a telomere loop ...

As described by Xin et al., in Genome Biology in 2008, telomeres are nucleoprotein structures at the ends of eukaryotic chromosomes. These structures help maintain eukaryotic genome integrity by ...

In normal mammalian cells, a small telomeric DNA segment is lost after each cell cycle, gradually eroding to a critical length. At this point, DNA repair systems recognize it as DNA damage and trigger ...

Jayakrishnan Nandakumar, Elaine R. Podell, Thomas R. Cech, Titia de Lange, How Telomeric Protein POT1 Avoids RNA to Achieve Specificity for Single-Stranded DNA, Proceedings of the National Academy of ...

The structure of TPP1's oligonucleotide binding fold contains features that are particularly characteristic of TEBPβ. When the POT1–TPP1 complex is bound to telomeric DNA, it does not inhibit ...

By using a DNA probe that specifically hybridizes to the telomeric region of human chromosomes, we were able to test this assertion directly. After scanning more than 200 dicentrics produced in normal ...

Telomeric repeat-containing RNA (TERRA) constitutes a nucleoprotein component of extracellular inflammatory exosomes. Proceedings of the National Academy of Sciences, 2015; 201505962 DOI: 10.1073 ...

Telomeric mononucleosomes have been found to be hardly detectable in such experiments since they are highly sensitive to overdigestion with micrococcal nuclease. 23 These results clearly show that ...
