TRF2-Mediated Control of Telomere DNA Topology as a Mechanism for Chromosome-End Protection

Eric Aeby

The shelterin proteins protect telomeres against activation of the DNA damage checkpoints and recombinational repair. We show here that a dimer of the shelterin subunit TRF2 wraps similar to 90 bp of DNA through several lysine and arginine residues localiz ...

A quantitative telomeric chromatin isolation protocol identifies different telomeric states

Joachim Lingner, Marc Moniatte, Romain Hamelin, Florence Armand, Diego Chiappe, Eric Aeby, Larissa Grolimund

Telomere composition changes during tumourigenesis, aging and in telomere syndromes in a poorly defined manner. Here we develop a quantitative telomeric chromatin isolation protocol (QTIP) for human cells, in which chromatin is cross-linked, immunopurified ...

Peroxiredoxin 1 Protects Telomeres from Oxidative Damage and Preserves Telomeric DNA for Extension by Telomerase

Joachim Lingner, Viesturs Simanis, Wareed Ahmed, Sophie Redon, Eric Aeby

Oxidative damage of telomeres can promote cancer, cardiac failure, and muscular dystrophy. Specific mechanisms protecting telomeres from oxidative damage have not been described. We analyzed telomeric chromatin composition during the cell cycle and show th ...

ALT Telomeres Get Together with Nuclear Receptors

Joachim Lingner, Eric Aeby

Nuclear receptors bind chromosome ends in "alternative lengthening of telomeres" (ALT) cancer cells that maintain their ends by homologous recombination instead of telomerase. Marzec et al. now demonstrate that, in ALT cells, nuclear receptors not only tri ...
