Research Overview

Colon cancer is the second highest cause of cancer deaths in Australia after lung cancer. The lifetime risks of contracting colon cancer and dying from this disease are 1 in 10 and 1 in 30, respectively. The Heath laboratory is interested in identifying genes and biological pathways that govern intestinal development and colon cancer formation.

Colon cancers develop in the cellular lining (intestinal epithelium) of the large bowel. The over-arching premise of our work is that the rapidly developing zebrafish intestinal epithelium is an excellent model for colon tumour growth. This proposition stems from the fact that developing organs and cancer tissues exhibit several common behaviours, including rapid growth and proliferation, cell migration, blood vessel development and cell death. Due to their external development and optical transparency, zebrafish larvae provide an excellent model for studying these dynamic cellular processes in real time.

Over the last decade, we have discovered several genes that upon mutation disrupt the growth and development of the zebrafish intestinal epithelium. A large part of our research is now focused on determining whether the aberrant expression of these genes may contribute to the formation of colon cancer in mice and humans.
