PHILADELPHIA and REHOVOT, Israel, June 4, 2013 /PRNewswire/ --Rosetta
Genomics Ltd. (NASDAQ: ROSG), a leading developer and provider of
microRNA-based molecular diagnostics, announces plans to expand its U.S.
commercial footprint from five sales territories currently to 12 territories
beginning in July 2013. In addition, the Company reports the successful
launch of its new corporate and product branding at the recent American
Society of Clinical Oncology Annual Meeting (ASCO 2013).

"Our Rosetta Cancer Origin Test™ (formerly miRview^® mets²) has been trending
positively for the past three months in terms of samples processed and samples
billed. We continue to make progress in executing agreements with Preferred
Provider Organizations (PPOs), such as our recently announced credentialing
agreement with Prime Health, which now allow for this test to be adjudicated
as 'in network' for more than 6.5 million patients in the U.S. Our strong
presence at ASCO 2013 significantly enhanced the knowledge of and interest in
our microRNA-based cancer testing services. Consequently, we believe the time
is right for a strategic expansion of our sales force in order to achieve
greater reach to physicians, and ultimately to ensure that our Cancer Origin
Test^™ is available to more patients," said Kenneth A. Berlin, Rosetta
Genomics' President and Chief Executive Officer.

Rosetta Genomics unveiled its new corporate and product branding at ASCO 2013
through various mediums including an interactive tradeshow booth that featured
a high-definition promotional video and various other promotional materials.
The new branding includes an updated corporate logo with the tagline,
"expanding personalized medicine," and new names and logos for Rosetta's
Cancer Testing Services (formally the miRview^® family of testing services),
all of which were extremely well received by healthcare professionals who
visited the booth.

In addition, Rosetta's Cancer Testing Services were highlighted in an
"Industry Expert Theater Presentation" (IETP), during which Mr. Berlin and E.
Robert Wassman, MD, FAAP, FACMG, Rosetta Genomics' Chief Medical Officer,
delivered a presentation entitled, "Application of microRNAs in Oncology
Diagnostics." Dr. Wassman delivered a presentation on the Cancer Origin
Test^™. During his presentation, Dr. Wassman discussed real-world case
studies of patients with Cancer of Unknown or Uncertain Primary (CUP) impacted
by the test results, and reviewed data from extensive validation studies that
demonstrated a high level of concordance with the predictions made by leading
CUP centers.

"We are delighted with the positive reception to our IETP, and with the
caliber of questions asked. We believe that through educational programs like
this and our other physician outreach efforts, physicians are beginning to
acknowledge the clinical value of microRNA profiling in CUP patients, and
recognize that it is not a matter of whether to use such diagnostics but when
to use them. In many cases a diagnosis of Cancer of Unknown Primary is no
longer acceptable now that we have more precise diagnostic assays to identify
the tumor of origin and, therefore, are able to make better clinical treatment
decisions," said Dr. Wassman.

Mr. Berlin added, "We received very favorable feedback on our new corporate
and product branding. We believe our modern new look and fresh promotional
materials, as well as our highly successful IETP, made a significant
contribution to the steady flow of visitors to our booth, and the subsequent
sales leads recorded. The positive responses confirmed that our new corporate
branding conveys who we are and what we do extremely well. In addition,
visitors to our booth gave highly positive feedback relating to the new names
and logos for our Cancer Testing Services, citing that they like the clear
connection between our corporate brand and what the tests actually do."

About Rosetta Cancer Testing Services (formerly the miRview^® product line)
Rosetta Cancer Tests are a series of microRNA-based diagnostic testing
services offered by Rosetta Genomics. The Rosetta Cancer Origin Test^™ can
accurately identify the primary tumor type in primary and metastatic cancer
including cancer of unknown or uncertain primary (CUP). Rosetta Mesothelioma
Test^™ diagnoses mesothelioma, a cancer connected to asbestos exposure. The
Rosetta Lung Cancer Test^™ accurately identifies the four main subtypes of
lung cancer using small amounts of tumor cells. The Rosetta Kidney Cancer
Test^™ accurately classifies the four most common kidney tumors: clear cell
renal cell carcinoma (RCC), papillary RCC, chromophobe RCC and oncocytoma.
Rosetta's assays 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 200,000
patients a year may benefit from the Rosetta Cancer Origin Test^™, 60,000 from
the Rosetta Mesothelioma Test^™, 65,000 from the Rosetta Kidney Cancer Test^™
and 226,000 patients from the Rosetta Lung Cancer Test^™. The Company's assays
are offered directly by Rosetta Genomics in the U.S., and through distributors
around the world. For more information, please visit
