Findings of disrupted micronuclei may prove to be a valuable tool for detecting cancer Scientists studying cancer development have known about micronuclei for some time. These erratic, small extra nuclei, which contain fragments or whole chromosomes that were not incorporated into daughter cells after cell division, are associated with specific forms of cancer and are predictive of poorer prognosis. In a new study, published on July 3 in Cell, a team of scientists at the Salk Institute...

They are the Robinson Crusoes of the intracellular world -- lone chromosomes, whole and hardy, stranded outside the nucleus where their fellow chromosomes reside. Such castaways, each confined to its own "micronucleus," are often found in cancer cells, but scientists haven't known what role, if any, they play in the cancer process. In a paper published online on Jan. 18 by the journal Nature, Dana-Farber Cancer Institute researchers have mapped out a mechanism by which micronuclei could...
