Cell signalling is the process by which our cells communicate with each other and with their environment. Pathways that govern how cells proliferate, move, survive and differentiate represent key targets in cancer biology. Targeting cell signalling has proven extremely successful in cancer treatment – drugs such as Glivec, Herceptin and Iressa, all discovered as a result of our increased understanding of cell signalling, are being used to treat millions of patients worldwide.
