A cancer-memory connection

摘要

A protein whose overexpression is associated with many forms of cancer also controls the formation of connections between brain cells. Cyclin E drives cell proliferation and is found mostly in dividing cells, but is also present in the adult brain. Jarrod Marto and Piotr Sicinski at the Dana-Farber Cancer Institute in Boston, Massachusetts, and their colleagues reveal that, in non-dividing neurons in the mouse brain, the protein is involved in memory formation.
