Edinburgh scientists have identified the way a specific cell protein can trigger the spread of cancer. The study by researchers in the Cell Signalling Unit, University of Edinburgh Cancer Research Centre could pave the way for new drugs which limit the protein's ability to turn a normal cell cancerous. The protein, MDM2, normally functions to control the activity of a key cancer preventi...Imaging pinpoints brain regions that 'see the future'
