Oxidative stress at telomeres triggers internal DNA loops, TRF1 dissociation, and TRF2-dependent R-loops

Joachim Lingner, Wareed Ahmed, Thomas Frédéric Lunardi, Thu Trang Nguyen, Eftychia Kyriacou

Telomeres are the nucleoprotein structures at chromosome ends. Telomeres are particularly sensitive to oxidative stress, which can induce telomere damage, shortening, and premature cellular senescence. How oxidative damage influences telomere structure has ...

PRDX1 Counteracts Catastrophic Telomeric Cleavage Events That Are Triggered by DNA Repair Activities Post Oxidative Damage

Joachim Lingner, Wareed Ahmed

Telomeres are prone to damage inflicted by reactive oxygen species (ROS). Oxidized telomeric DNA and nucleotide substrates inhibit telomerase, causing telomere shortening. In addition, ROS can induce telomeric single-strand DNA breaks (SSBs). The peroxired ...

SMCHD1 promotes ATM-dependent DNA damage signaling and repair of uncapped telomeres

Joachim Lingner, Verena Pfeiffer, Wareed Ahmed, Aleksandra Vancevska, Marianna Feretzaki

Structural maintenance of chromosomes flexible hinge domain-containing protein 1 (SMCHD1) has been implicated in X-chromosome inactivation, imprinting, and DNA damage repair, and mutations in SMCHD1 can cause facioscapulohumeral muscular dystrophy. More re ...
