This news item is about: Cancer cells must prepare for travel before invading new tissues, but new Cornell research has found a possible way to stop these cells from ever hitting the road. Researchers have identified two key proteins that are needed to get cells moving and have uncovered a new pathway that treatments could block to immobilize mutant cells and keep cancer from spreading, says Richard Cerione, Goldwin Smith Professor of Pharmacology and Chemical Biology at Cornell’s College of Veterinary Medicine.
