NYU Langone Medical Center researchers find micro RNA plays a key role in melanoma metastasis

NEW YORK CITY (February 5, 2009)Scientists have long wondered how melanoma cells travel from primary tumors on the surface of the skin to the brain, liver and lungs, where they become more aggressive, resistant to therapy, and deadly. Now, scientists from NYU Langone Medical Center have identifi...
