Cardiovascular and Tumourivascular Laboratory

Research Overview

The Cardiovascular and Tumourivascular Laboratory is co-headed by Dr Peter Wookey and Professor David Hare.

The group focuses on the discovery of new membrane and other targets in cardiovascular diseases and cancer. 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. The translational model involves a collaboration with a biotech start-up company.

Antibodies have been raised against G protein-coupled receptors (GPCR) including extracellular epitopes, which have been notoriously elusive. Antibodies against one such epitope within this domain of the calcitonin receptor (CTR) have been useful for live staining of cells undergoing stress and programmed cell death, as well as expression in inflammation and brain tumours. An anti-NPY1 receptor antibody has also been characterised for studies on breast cancer and appetite. Both antibodies bind unique epitopes in the extracellular domains of their respective GPCR.

As an example of project development, the brain tumour (glioblastoma, GBM) project began with collaboration between our laboratory and neurosurgeons at the Alfred and led to the discovery of expression of CTR by glioma stem cells (GSCs, cancer stem cells). The pathway to the clinic has involved the development of an immunotoxin with an anti-CTR antibody conjugated to a plant toxin and the induction of cell death of GSCs.
