How do cancer-associated extrachromosomal circular DNAs arise?
In our new manuscript, we show that single-strand DNA damage in repetitive sequences can trigger i-loop formation and eccDNA generation. What started at telomeres may reflect a much broader principle across the genome and help explain how ecDNA may emerge in cancer.
