Cardiovascular and Tumourivascular Laboratory
The Cardiovascular and Tumourivascular Laboratory is co-headed by Dr Peter Wookey and Professor David Hare.
The group focuses on the discovery of new targets, predominantly membrane proteins, in cancer and cardiovascular diseases. Cancer stem cells are an important target of our research. Each of the four projects begins with the development of novel antibodies which provide us with the tools for basic research and a pipeline for translational research. Of significance, antibodies have been raised against G protein-coupled receptors (GPCR) including extracellular epitopes, which have been notoriously problematic. The translational model involves collaborations with Pharma.
Novel antibodies against an epitope within the extracellular domain of the calcitonin receptor (CT Receptor) have been useful for imaging live cells undergoing stress and programmed cell death. A theoretical model for the function of CT Receptor in cell stress is being interrogated.
The brain tumour (glioblastoma) project involved the discovery of CT Receptor expressed by glioma stem cells (GSCs), the development of an anti-CT Receptor immunotoxin and the induction of cell death of GSCs. The pathway to the clinic has involved a collaboration with a group in Berlin, Germany, and an EU-based consortium for the Grand Cancer Challenges.
A novel anti-NPY1 receptor antibody is being validated for studies on breast and brain cancers.
