Shutting down DNA construction: How senescence halts growth of potential cancers

Researchers discovered that oncogene-induced senescence can suppress cancer development by depriving cells of nucleotides, the building blocks of DNA. By targeting the RRM2 enzyme, which produces these nucleotides, scientists may be able to stabilize senescence and improve the effectiveness of chemotherapy or targeted drugs.
