Summary
Gastric cancer is a major cause of morbidity and death worldwide. We have previously established a very informative animal model of this disease which has facilitated a new understanding of the diverse role of the IL-6 family of cytokines in regulating gastric tumour growth and dissemination to distant organs. This proposal will focus on how the main members of this cytokine family, namely IL-6 and IL-11, inhibit gastric tumour invasion to other organs, and promote tumour growth respectively .

This proposal will focus on how the main members of this cytokine family, namely IL-6 and IL-11, inhibit gastric tumour invasion to other organs, and promote tumour growth respectively . An understanding of these processes will aid in designing therapeutic interventions specific for each cytokine and which may lead to drugs aimed at limiting or reversing this disease.Read moreRead less
Interstitially Invasive Trophoblast Of The Murine Placenta: Developmental Origins, Functions And Gene Expression.

Summary
Due to the obvious limitations to studying human pregnancy, the mouse has become a valuable model. However, invasion of the placenta into the uterine wall and vasculature, critical for successful pregnancy, is poorly understood in the mouse. The aims of the proposal are designed to gain a better understanding of these processes in mice and will provide a more accurate model system to study serious pregnancy complications resulting from abnormal placental invasion, such as preeclampsia.

Summary
This research proposal investiagtes the role of a molecule known as histidine-rich glycoprotein (HRG) in the important diseases of cancer and inflammation. Inflammatory diseases can occur when the the normal checks on the immune system breakdown resulting in attacks on the body leading to tissue damage (e.g rheumatoid arthritis) and are significant contributors to morbidity and health costs in Australia. Cancer is the leading cause of death in Australia (28.4% of deaths in 2003).

Inflammatory diseases can occur when the the normal checks on the immune system breakdown resulting in attacks on the body leading to tissue damage (e.g rheumatoid arthritis) and are significant contributors to morbidity and health costs in Australia. Cancer is the leading cause of death in Australia (28.4% of deaths in 2003). HRG has been implicated in controlling important aspects of inflammatory and cancer disease progression. Namely, HRG appears to regulate the formation and clearance of substances known as immune complexes - the primary cause of tissue damage in this disease. Furthermore, HRG may also control the process of cell invasion which is crucial for the migration of white blood cells of the immune system (leukocytes) to sites of inflammation to combat infections, and is also an important mechanism by which malignant tumour cells escape from primary tumour sites and spread throughout the circulation to other sites in the body. It is this process that makes cancer such a deadly disease. This study aims to define how HRG contributes to these important processes. This information may allow the development of new therapeutic approaches for the treatment of inflammatory diseases and cancer.Read moreRead less
The Role Of Eph/ephrin Clustering And Trafficking In Control Of Tumour Cell Invasion

Summary
Eph and ephrin proteins are important for normal development of the embryo by controlling cell positioning. In adult tissues these proteins are present at low levels but are found at high levels in human cancers, including skin cancers, where their presence is thought to promote aggressive tumours. We wish to understand how these proteins control cell movement and contribute to cancer progression so that we can develop new cancer therapies.
