DNA Damage Induces Alternative Lengthening of Telomeres (ALT)–Associated Promyelocytic Leukemia Bodies that Preferentially Associate with Linear Telomeric DNA
25 Jul 2007
Abstract excerpt
The linear chromosomes of vertebrates terminate in telomeres that consist of a tandemly repeated hexameric sequence, 5'TTAGGG3'. Telomeres form a protective loop structure (t-loop), which is thought to prevent them from being recognized as a double-strand break. Approximately 10% of human tumors prevent shortening of their telomeres by using a recombination-mediated alternative lengthening of telomeres (ALT)...
