Replacing absent microRNAs could make tumors less invasive, more treatable

One group of small, non-coding RNA molecules could serve as a marker to improve cancer staging and may also be able to convert some advanced tumors to more treatable stages, report a University of Chicago-based research team in the April 1, 2008, issue of the journal Genes & Development.
