Rosetta Genomics reports the following scientific and corporate highlights:

Diagnostic Programs

- Squamous vs. Non Squamous non-small cell lung cancer (NSCLC) - Columbia University Medical Center's Molecular Pathology Laboratory has submitted this test, designed to differentiate squamous from non squamous non-small cell lung cancer (NSCLC) using a single microRNA, for regulatory approval to the New York State Department of Health. The approval process is estimated to take 2-6 months.

The ability of physicians to accurately differentiate squamous from non-squamous NSCLC is an important treatment guide. Bevacizumab, an angiogenesis inhibitor and an important new modality of therapy for non-squamous NSCLC, includes a black-box warning about substantially higher rates of severe or fatal hemorrhage among patients with squamous NSCLC histology compared with non-squamous NSCLC.

- Mesothelioma vs. Adenocarcinoma - Differentiating between mesothelioma and adenocarcinoma is critical for optimal therapy, but it is often difficult to differentiate these tumors. Currently, there is no objective, standardized test to aid pathologists in differentiating between the many possible tumors in the lung and pleura. Based on a few microRNA biomarkers that were identified applying Rosetta Genomics' technology, a test is being developed to separate mesothelioma from adenocarcinoma tumors including lung adenocarcinoma and metastases to the lung or to the pleura. This test is expected to be filed for regulatory approval in H2 2008.

- Cancer of Unknown Primary (CUP) - We continued to advance assay development of a microRNA-based test for cancer of unknown primary (CUP). As demonstrated in a paper published by Rosetta Genomics and collaborators in the April issue of Nature Biotechnology, the test is being develo
