This study shows that repetitive sequences, which are ‘hotspots’ of DNA evolution, emerge early in tumor evolution but fade away in later phases, particularly during the transition to metastatic states, though they leave clear marks in the genome, said Eugene Koonin, Ph.D., a co-author of the study and head of NLM’s Evolutionary Genomics Research Group.
