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

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

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 ...

The human telomeric proteome during telomere replication

Joachim Lingner, Thomas Frédéric Lunardi, Aleksandra Vancevska, Gérald Joseph Paul Lossaint, Chih-Yi Gabriela Lin

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 sem ...

RAD51-dependent recruitment of TERRA lncRNA to telomeres through R-loops

Joachim Lingner, Thomas Frédéric Lunardi, Marianna Feretzaki, Rita Valador Fernandes

Telomeres-repeated, noncoding nucleotide motifs and associated proteins that are found at the ends of eukaryotic chromosomes-mediate genome stability and determine cellular lifespan1. Telomeric-repeat-containing RNA (TERRA) is a class of long noncoding RNA ...

CSL controls telomere maintenance and genome stability in human dermal fibroblasts

Joachim Lingner, Thomas Frédéric Lunardi, Paris Jafari

Genomic instability is a hallmark of cancer. Whether it also occurs in Cancer Associated Fibroblasts (CAFs) remains to be carefully investigated. Loss of CSL/RBP-J kappa, the effector of canonical NOTCH signaling with intrinsic transcription repressive fun ...
