Cedars-Sinai 'nano-drug' hits brain-tumor target found in 2001

Article Published in EurekAlert! on 4th November 2010

Nine years ago, scientists at Cedars-Sinai's Maxine Dunitz Neurosurgical Institute detected a subtle shift occurring in the molecular makeup of the most aggressive type of brain tumors, glioblastoma multiforme. With further study, they found that a specific protein called laminin-411 plays a major role in a tumor's ability to build new blood vessels to support its growth and spread. But technology did not exist then to block this protein.

Now, employing new drug-engineering technology that is part of an advanced science called nanomedicine, the research team has created a "nanobioconjugate" drug that may be given by intravenous injection and carried in the blood to target the brain tumor. It is engineered to specifically permeate the tumor cell wall, entering endosomes, mobile compartments within cells.
