The majority of cancer deaths are related to the spread of cancer ( metastases) to a new organ in the body. Breast cancer may eventually spread to the brain, while bone and lung cancers can spread throughout the body. A new technology developed by researchers at Cornell utilizes a novel protein called Trail to stop the spread of these moving cancer cells. Attaching Trail to an innovative nanoparticle enables the cancer-killing package to find cancer cells in the blood stream and kill them before residing in a new organ. In several human and animal models, Cornell researchers have showed the disintegration of a significant portion of the moving cancer cells upon administration of their novel nanotechnology.
