RNA snippet suppresses spread of aggressive breast cancer
CAMBRIDGE, Mass. (June 11, 2009) A low cellular level of a tiny fragment of RNA appears to increase the spread of breast cancer in mouse models of the disease, according to researchers at Whitehead Institute for Biomedical Research.
Measuring levels of this so-called microRNA, which is also a...
