Aging: Fewer Obstacles to DNA Replication?

Research output: Contribution to journalShort surveypeer-review


Many cancers are initiated by loss-of-heterozygosity (LOH) events that lead to the replacement of single, functional tumor suppressor genes by the mutant alleles. The underlying mechanisms, of why LOH rates increase with age, are not well understood. We discuss the possible involvement of difficult-to-replicate (fragile) chromosomal sites in this process.
