Study reveals cancer cells' survival tactic
The new study reveals that some aggressive types of cancer, particularly those that rely on Alternative Lengthening of Telomeres (ALT), surpass the normal order of chromosomes by inserting parts of centromeric DNA into the telomeres. These chimeric sequences are frequently observed in pediatric neural tumors, which may provide a new method for detecting cancers that are difficult to diagnose and treat. The study explains that these structural changes allow cancer cells to survive even after telomeres shorten by copying telomeric sequences from one chromosome to another, thereby enhancing genomic stability and influencing tumor development.
