FOSTER CITY, Calif.--(BUSINESS WIRE)--Scientists at Cold Spring Harbor Laboratory (CSHL), Howard Hughes Medical Institute (HHMI), and Applied Biosystems (NYSE: ABI), an Applera Corporation business, have discovered that a family of small RNA molecules known as microRNAs (miRNAs) are components in a well-studied tumor suppressor network, the p53 pathway, that stops the growth of tumor cells in mice. This tumor suppressor capability represents a newly discovered function for miRNAs. The finding may also suggest new approaches for treating cancers. The results of the team’s two-year collaboration will be published in the June 28th issue of the journal Nature. Other co-authors were from Stony Brook University and Rosetta Inpharmatics.
