CHARLOTTESVILLE, Va., April 25, 2007 -- University of Virginia researchers have discovered that microRNAs, a form of genetic material, can function as tumor suppressors in laboratory studies. In the May 1 issue of Genes & Development, UVa researchers Drs. Yong Sun Lee and Anindya Dutta have shown that microRNAs can suppress the overexpression of a gene called HMGA2.
