Summary
The main complication in breast cancers leading to death is metastatic relapse. This research aims to understand the role for a protease that promotes spread of breast cancer to the lymph nodes and lungs. The outcomes will identify a novel process that leads to lymph node metastasis and offer a new target for therapies that prevent relapse and tests to identify breast cancer patients at risk of relapse.
MMP13 is upregulated in cancer cells and in the tissue that forms around the cancer (stroma). A new MMP13-specific inhibitor reduces breast cancer growth in a mouse model, both at the primary site and also in bone. We will determine the role of MMP13 made by the cancer cells and stroma, respectively, extend the inhibitor work, and identify proteins being cleaved by MMP13. Being a late-stage manifestation, bone metastasis may represent an important clinical trial setting for MMP inhibitors.

Summary
Invasion and metastasis are major causes of death in cancer patients. Our research has uncovered a pathway that increases the invasive potential of tumour cells in vitro. We now aim to determine if the pathway is relevant in invasion and metastasis in clinically relevant models; how a drug targeting the pathway affects invasion and; the extent to which the pathway is active in human tumours. These studies may identify a new molecular target for anti-invasive drugs.

Summary
The protein “RECK” is known to have a controlling effect on cancers by reducing growth, invasion, and blood supply. RECK is present in normal tissues but in bone and soft-tissue tumours (sarcomas), the protein is reduced. This study aims to; correlate RECK levels in sarcoma with patient survival, use gene technology to increase RECK levels in sarcoma cells, and observe the effects on sarcoma invasion and metastasis.
Regulation of tissue morphogenesis in reproductive function and metastatic cancer. Infertility, endocrine and metabolic disorders and reproductive cancers are all increasing medical problems and principal contributors to morbidity and mortality in the Australian community.

Infertility, endocrine and metabolic disorders and reproductive cancers are all increasing medical problems and principal contributors to morbidity and mortality in the Australian community. This research takes the novel approach of investigating the mechanisms of dynamic remodeling in reproductive organs. Novel hormonally controlled mechanisms of tissue remodeling unique to reproductive organs and cancers in adults have been discovered. The results are being applied to new medical alternatives for infertile patients and new diagnostics and therapeutics for patients with metastatic cancers. The information is also being applied to improve reproductive efficiency in animal production industries.Read moreRead less
The role of retinoic acid signalling in the development of the oesophageal epithelium. Oesophageal adenocarcinoma (OAC) is a disease with increasing incidence. The majority of patients with OAC are diagnosed when the cancer is at a late stage and therefore treatment options are limited, meaning the disease is almost invariably fatal. OAC arises from the precancerous condition, Barrett's oesophagus, which occurs as a consequence of chronic reflux, although the key processes driving its developmen ....The role of retinoic acid signalling in the development of the oesophageal epithelium. Oesophageal adenocarcinoma (OAC) is a disease with increasing incidence. The majority of patients with OAC are diagnosed when the cancer is at a late stage and therefore treatment options are limited, meaning the disease is almost invariably fatal. OAC arises from the precancerous condition, Barrett's oesophagus, which occurs as a consequence of chronic reflux, although the key processes driving its development are unknown. This project aims to better understand the critical first step in the progression to cancer and thus expand the scope for the development of therapies, particularly those aimed at early intervention, and tools that predict progression.Read moreRead less
