How cells solve their identity crisis

LA JOLLA—Cancer is often the result of DNA mutations or problems with how cells divide, which can lead to cells “forgetting” what type of cell they are or how to function properly. Now, Professor Martin Hetzer and a team of scientists have provided clarity into how new cells remember their identity after cell division. These memory mechanisms, published in Genes & Development on June 4, 2020, could explicate problems that occur when cell identity is not maintained, such as cancer.
