Multitasking microRNA regulates metastasis

Multitasking microRNA regulates metastasis - Understanding how a tumor switches from sustaining growth in just one part of the body to disseminating secondary tumors throughout the body, a process called metastasis, is a key goal of cancer research. Dr. Robert Weinberg and his colleagues have identified a microRNA that suppresses metastasis at several different stages of the process by virtue of its ability to coordinately target and repress a set of metastasis-promoting genes.
