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 have identified the possible culprit -- a short strand of RNA called microRNA that is over-expressed in metastatic melanoma cell lines and tissues.
