Rosetta Genomics Announces Commercial Availability of Its Third MicroRNA-Based
Diagnostic Test: miRview(TM) meso
The Company now has Three Commercially Available Molecular Diagnostic Tests
for Cancer

REHOVOT, Israel, JERSEY CITY, New Jersey and PHILADELPHIA, Pennsylvania,
December 29 /PRNewswire-FirstCall/ -- Rosetta Genomics, Ltd. (NASDQ: ROSG),
the leading developer of microRNA-based molecular diagnostics, announced
today the introduction of its third diagnostic test, miRview(TM) meso. The
test is now commercially available through Rosetta Genomics CLIA-certified
lab in Philadelphia.
To order the test, physicians may contact 1-888-522-7971, or visit the
company's website http://www.rosettagenomics.com.
"I am very excited to finally see a molecularly-based test that can
objectively differentiate mesothelioma from several types of carcinomas in
the lung with such high level of accuracy" noted Harvey Pass, MD, Division
Chief for Thoracic Surgery and Thoracic Oncology at the New York University
Langone Medical Center. "Ruling out Mesothelioma from lung cancer for
individuals that were exposed to asbestos can be difficult and challenging. I
am sure that this test will become an important tool for both oncologists and
pathologists in obtaining the right diagnosis in these patients."
Malignant pleural mesothelioma is directly linked to exposure to asbestos
particles, as well as to various heavy metals. Rescue workers, shipyard
workers, and miners are at increased risk of developing mesothelioma.
Currently, there is no single diagnostic test that is entirely conclusive for
this differentiation. In addition, pathological diagnosis may suffer from
significant inter-observer variability, and in the absence of a single
specific and reliable test, mesothelioma can be difficult to identify from
other cancers.
miRview(TM) meso differentiates mesothelioma, a cancer connected to
asbestos exposure, from other carcinomas in the lung. Currently, there is no
single diagnostic test that is entirely conclusive for this differentiation.
Each year, approximately 130,000 patients in the United States are diagnosed
with adenocarcinoma of the lung. miRview(TM) meso is available for $3170.
Rosetta Genomics currently has approximately $16M in cash, and it expects
to perform approximately 2,000 tests during 2009 in its laboratory in
Philadelphia, PA.
The company is now offering the following ground-breaking tests through
its clinical lab in Philadelphia:
- miRview(TM) mets - This test can accurately identify the
primary tumor site in patients presenting with metastatic cancer, as well
in patients with Cancer of Unknown Primary (CUP). In the U.S., hundreds
of thousands of patients are diagnosed each year with metastatic cancer,
and approximately 70,000 patients are labeled CUP patients. miRview(TM)
mets is available for $3650.

- miRview(TM) squamous - This test differentiates between two
subtypes of non small cell lung cancer (NSCLC). This diagnosis is
important as some NSCLC patients have demonstrated varying response
patterns ranging from a high incidence of severe or fatal internal
bleeding in the lungs to overall poor response to treatment. In the US
alone, approximately 170,000 patients are diagnosed each year with NSCLC.
miRview(TM) squamous is available for $3170.

- miRview(TM) meso - This test differentiates mesothelioma, a
cancer connected to asbestos exposure, from other carcinomas in the lung.
Currently, there is no single diagnostic test that is entirely conclusive
for this differentiation. Each year, approximately 130,000 patients in
the United States are diagnosed with adenocarcinoma of the lung.
miRview(TM) meso is available for $3170.

About microRNAs
MicroRNAs (miRNAs) are recently discovered, naturally occurring, small
RNAs that act as master 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 in various pathological conditions. As a result,
these differences may provide for a novel diagnostic strategy for many
diseases.
About Rosetta Genomics
Rosetta Genomics (Nasdaq: ROSG) is a leading developer of microRNA-based
molecular diagnostics. 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 proprietary platform
technologies, Rosetta Genomics is working on the application of these
technologies in the development of a full range of microRNA-based diagnostic
tools. The company have their first three microRNA-based tests, miRview(TM)
squamous, miRview(TM) mets, and miRview(TM) meso, commercially available
through its Philadelphia-based CLIA-certified lab.
