REHOVOT, Israel and NEW YORK, October 2 /PRNewswire-FirstCall/ --

- Management and Distinguished Scientists Will Provide Overview on Company’s Diagnostic and Therapeutic Development Programs, as Well as on the microRNA Field

Rosetta Genomics, Ltd. , a global leader in microRNA-based diagnostics and therapeutics, announced today it will host its R&D Day on microRNAs and their significant potential in cancer treatment and other medical applications. This event will take place on Friday, October 26, from 12:00 pm-3:00 pm (New York time), and will be webcasted live on the “Investors” section of the company’s website at http://www.rosettagenomics.com.

Amir Avniel, Chief Executive Officer of Rosetta Genomics, and Dalia Cohen, Ph.D., Executive Vice President, Global Head of Research & Development, will provide an overview of the company’s development and commercialization plans for microRNA-based diagnostics and therapeutics, as well as its Intellectual Property.

In addition, the following leading scientific experts will provide their insights on microRNAs’ future role in therapeutics and diagnostics:

Harvey Pass, MD, Professor and Chief, Division of Thoracic Surgery and Thoracic Oncology at NYU Medical Center.

Mahesh Mansukhani, MD, Associate Director of the Molecular Pathology Laboratory at Columbia University Medical Center

Prof. Moshe Hod, Director, Division of Maternal Fetal Medicine, Helen Schneider Hospital for Women, Rabin Medical Center

Eva M Hernando-Monge Ph.D., B.S., Assistant Professor, Department of Pathology, New York University School of Medicine

“As microRNAs are a relatively new field of study, there is significant demand to obtain a broader knowledge of microRNAs and their commercial potential,” stated Mr. Avniel. “Our distinguished panel of speakers will give a unique insight into how new technologies are integrated into medical practice and the impact these discoveries have on patient care.”

This invitation-only event will be webcasted and posted on the Rosetta Genomics website. To access the live audio webcast for this conference, please log on to the Rosetta Genomics website at http://www.rosettagenomics.com approximately 15 minutes prior to the presentation in order to register and download any necessary software. A replay of the audio presentation will be available following the event.

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, microRNAs have been shown to have different expression levels in certain diseased versus normal tissues. As a result, these differences potentially provide for a novel diagnostic strategy for many diseases. MicroRNAs are thought to play a key role in the differentiation of cells into specific cell types performing various functions in the body.

About Rosetta Genomics

Rosetta Genomics is a leader in the development of microRNA-based diagnostics and therapeutics. Founded in 2000, the company’s integrative research platform combining bioinformatics and state-of-the-art laboratory processes has led to the discovery of hundreds of biologically validated novel human microRNAs. Building on its strong IP position and strategic alliances with leading biotechnology companies, Rosetta Genomics is working to develop a full range of diagnostic and therapeutic products based on microRNAs. The company’s primary focus is in the development of microRNA-based products to diagnose and treat different forms of cancer and other diseases.
