Cardiovascular and Tumourivascular Laboratory
Research in our laboratory has discovered an important role for calcitonin receptor (CTR) in the adaptive response of cells to stress that precedes the onset of apoptosis . Expression of CTR has been found in stressed tissues in cardiovascular disease such as unstable atheroscerotic plaque, in wound healing and in particular cancers. Specific antibodies against extracellular and intracellular epitopes of CTR have been developed. Utilities of these antibodies that are under development here include imaging programmed cell death (PCD) in vitro and in vivo, the reduction in tumour size of models of the brain tumour glioblastoma and the definition of intracellular events that form the basis of CTR involvement in cell stress and PCD.
A further interest is the characterization of an antibody target that is thought to represent a high affinity ligand of CTR in human cells. This protein has been identified on immunoblots and by confocal microscopy with a unique antibody developed in our laboratory. On-going research is directed towards the purification of the target protein, its sequence and the full description of the associated molecular biology.
