The cardiac and vascular systems and disease
 

We are dedicated to generating fundamental knowledge in cardiovascular biology that can be translated into clinical progress. To achieve this, we collaborate with clinicians in Australia and Internationally. There are several major disease areas that benefit from the developmental, stem cell, regenerative and chemical biology studies that we perform:

 


Congenital heart defects

With our stem cell, tissue engineering and animal models, we are identifying novel regulators of cardiac development and function. These regulators are what are defective in congenital heart disease and it is through understanding these regulators and building a roadmap of heart development that makes it possible to make sense of the causes of congenital heart disease. In additional to using these model systems, we are actively collaborating with cardiologists to sequence patients to identify the underlying cause of each patient’s congenital heart defect.

Congenital disorders of the vascular system

Like congenital heart disease, there are numerous inherited disorders of the vascular system that we are currently studying. Prominent examples include Hennekam and Hypotrichosis-Lymphedema-Telangiectasia syndromes and our research into CCBE1 and SOX18, the respective genes mutated in these disorders, has been pivotal for identifying and assigning diagnostics for these disorders. Our ongoing genetic screens in zebrafish and mice continue to discover new genes and pathways in cardiovascular development. All of these represent candidates in cardiovascular pathologies and we collaborate with clinicians on specific findings as they arise.

Cancer metastasis

Solid cancers spread (metastasize) to distant organs via the vascular system. Many tumors produce growth factors that stimulate the growth of a tumor vascular system. The tumor vasculature provides it with nutrients and oxygen for growth. It also provides a route for the cancer to access the rest of the body. We study growth factors that stimulate the tumor vascular system and investigate how they are secreted, what controls their release and processing and how they signal to a receiving cell. This knowledge is paramount for devising strategies to combat tumour growth and spread. As well as studying growth factor biology, we are also developing high-throughput drug screening platforms in an effort to identify new compounds for drug development against tumour vascular growth.

Aging, wound healing and regenerative medicine

As we age, our tissue degenerates and our ability to heal deteriorates. By using regenerative animal modelling and stem cell research, we are investigating the barriers that our bodies put in place as they age to prevent our ability to regrow sick or damaged tissue. One example is our failure to repair our hearts after cardiac injury, such as a heart attack – the most common cause of death in the western world. We are investigating cardiomyocyte biology to determine how we can reactivate this tissue to regrow after tissue damage and we are investigating revascularisation strategies to assist in that repair.
