Rosetta Genomics Ltd. In-Licenses Proprietary MicroRNAs for Therapeutic use From Rockefeller University

REHOVOT, Israel and NORTH BRUNSWICK, New Jersey, June 13 /PRNewswire-FirstCall/ -- Rosetta Genomics , a leading microRNA company, announced today it has signed a licensing agreement with Rockefeller University for the therapeutic application of proprietary microRNA genes. The addition of these viral and human microRNAs to the Company’s existing intellectual property estate gives Rosetta Genomics access to over 500 proprietary microRNA drug targets. This vast intellectual property portfolio covering a wide range of novel targets, coupled with Rosetta Genomics’ extensive know how in the field of microRNAs and cutting edge technologies, establishes the company as a key leader in the research and development of microRNA-based therapeutics and diagnostics.

MicroRNAs have been shown to hold tremendous potential as a new class of prospective drug targets with significant therapeutic opportunity. Rosetta Genomics’ lead therapeutic development program for liver cancer (hepatocellular carcinoma or HCC), being conducted in collaboration with Isis Pharmaceuticals, Inc. , has so far identified four microRNAs that when inhibited in vitro lead to a decrease in liver cancer cell proliferation. Human and viral microRNA targets are expected to play a role in the regulation of key disease processes in major therapeutic areas such as oncology, metabolism and infectious diseases. The liver cancer program at Rosetta Genomics is being funded in part by the Binational Industrial Research and Development Foundation (BIRD).

“Rosetta Genomics intends to continue to expand what we believe to be the dominant intellectual property estate related to microRNA genes for diagnostic and therapeutic uses,” said Amir Avniel, President and CEO of Rosetta

Genomics. “Our strategy is to supplement our in-house IP efforts through licensing agreements with key academic centers such as Rockefeller University. The proprietary human and viral microRNAs brought to us through this important relationship will provide us access to even more potential drug targets. We are encouraged with the preliminary in vitro results in our liver cancer program and see the addition of these microRNAs as essential to the development of a robust and broad therapeutic pipeline.”

In addition to its therapeutic development program, Rosetta Genomics is advancing several cancer diagnostic products in its pipeline. The Company’s leading product in development is a diagnostic test for Cancer of Unknown Primary which is designed to assist oncologists in determining the origin of metastases. Rosetta Genomics plans to launch the CUP diagnostic test in the second half of 2008.

About microRNAs

MicroRNAs (miRNAs) are a recently discovered, naturally occurring form of RNAi. These small RNAs act as protein regulators and have the potential to form the basis for a new class of diagnostics and therapeutics. Since many diseases are caused by the abnormal activity of proteins, the ability to selectively regulate protein activity through microRNAs could provide the means to treat a wide range of human diseases. In addition, microRNA expression levels have been shown to be correlated with various disease states and to hold great potential as diagnostics and prognostic markers

About Rockefeller University

The Rockefeller University is a world-renowned center for research and graduate education in the biomedical sciences, chemistry, and physics. Founded by John D. Rockefeller in 1901, the university has been the site of many important scientific breakthroughs. Rockefeller scientists established that DNA is the chemical basis of heredity, discovered blood groups, showed that viruses can cause cancer, founded the modern field of cell biology, and worked out the structure of antibodies. Twenty-three Nobel Prize winners have been associated with the university.
