Abstract:Proliferating cells must enact a program of telomere lengthening to counteract the chromosome end replication problem. In most types of cancer cells, telomeres are maintained through the action of the ribonucleoprotein telomerase, but some cancer cells, particularly those of mesenchymal origin, utilize an alternative method of telomere repair and lengthening termed the alternative lengthening of telomeres (ALT) pathway. Since telomere maintenance is essential for tumor cell immortality, better understanding of… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
