"We are especially pleased to be presenting this growing body of clinical data in support of the clinical utility of our miRview® diagnostic tests to accurately identify and classify various cancers at the prestigious ASCO conference. We recently launched our first company-led commercialization efforts in the U.S., and these data enhance the visibility of our miRview® diagnostics before an audience of the world's leading oncologists," commented Kenneth A. Berlin, President and Chief Executive Officer of Rosetta Genomics. "These data also enhance our commercial efforts by providing our sales team with the clinical support needed for widespread adoption of our miRview diagnostics in oncology."

About miRview® Products
miRview® are a series of microRNA-based diagnostic products offered by Rosetta Genomics. miRview® mets and miRview® mets2 accurately identify the primary tumor site in metastatic cancer and CUP. miRview® squamous accurately identifies the squamous subtype of non-small cell lung cancer, which carries an increased risk of severe or fatal internal bleeding and poor response to treatment for certain therapies. miRview® meso diagnoses mesothelioma, a cancer connected to asbestos exposure. miRview® tests are designed to provide objective diagnostic data; it is the treating physician's responsibility to diagnose and administer the appropriate treatment. In the U.S. alone, Rosetta Genomics estimates that approximately 200,000 patients a year may benefit from the miRview® mets and miRview® mets2 test, 60,000 from miRview® squamous and 60,000 from miRview® meso. The Company's tests are offered directly by Rosetta Genomics in the U.S., and through distributors around the globe.

About microRNAs
microRNAs (miRNAs) are recently discovered, small RNAs that act as master regulators of protein synthesis, and have been shown to be highly effective biomarkers. The unique advantage of microRNAs as biomarkers lies in their high tissue specificity, and their exceptional stability in the most routine preservation methods for biopsies, including Formalin Fixed Paraffin Embedded (FFPE) block tissue and fine needle aspirate (FNA) cell blocks. It has been suggested that their small size (19 to 21 nucleotides) enables them to remain intact in FFPE blocks, as opposed to messenger RNA (mRNA), which tends to degrade rapidly. In addition, early preclinical data has shown that by controlling the levels of specific microRNAs, cancer cell growth may be reduced. To learn more about microRNAs, please visit
