Research description

In terms of basic science we are interested in how protein kinase and lipid signalling pathways control cell fate decisions such as proliferation versus differentiation and survival versus death. However, these pathways are frequently de-regulated in human cancer due to mutations in growth factor receptors, KRAS, BRAF or PI3K (or PTEN loss). As a result, tumours frequently evolve to be 'addicted' to these oncoproteins or the signalling pathways they control. This makes them attractive targets for therapeutic intervention and new drugs that target these pathways are in development or are entering the clinic; for example, the MEK1/2 inhibitor AZD6244 which blocks the BRAF-MEK1/2-ERK1/2 signalling pathway. We are interested in understanding why some tumours are intrinsically resistant to such drugs, how cells adapt to long term exposure to these drugs ('acquired resistance') and the remodelling of signalling pathways that this entails.
