STANFORD, Calif.--(BUSINESS WIRE)--You know the guy—he’s your Facebook friend. The one who knows everyone. Secure at the center of a dense web of relationships, he suggests causes and reconnects old friends like a skilled matchmaker. Scientists have known for some time that biological molecules interact with one another in a similarly complex pattern. Now researchers at the Stanford University School of Medicine have determined that hamstringing these molecular powerbrokers is a good way to derail processes such as cancer development.
