with squamous NSCLC histology compared with non-squamous NSCLC. In
addition, several other targeted drugs for NSCLC currently under
development may require this sensitive differentiation.
- Mesothelioma vs. Adenocarcinoma - Differentiating between mesothelioma
and adenocarcinoma is critical for optimal therapy, but it is often
difficult to differentiate. Currently, there is no objective,
standardized test to aid pathologists in differentiating between the
many possible tumors in the lung and pleura. Based on several microRNA
biomarkers, this test is designed to separate mesothelioma from
adenocarcinoma tumors including lung adenocarcinoma and metastases to
the lung or to the pleura
- Cancer of Unknown Primary (CUP) - In 3%-5% of all new cancer patients,
clinicians cannot identify the origin of a patients' tumor. This
information is crucial for determining treatment type.
As demonstrated in a paper published by Rosetta Genomics and collaborators in the April issue of Nature Biotechnology, Rosetta Genomics has developed a panel of microRNA biomarkers potentially able to identify approximately thirty cancer types. This test is designed to assist clinicians to accurately identify the origin of tumors.
About MicroRNA
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.
