Summary
We discovered and manufactured a growth factor produced uniquely by the egg. We named this growth factor cumulin. It is a powerful regulator of ovarian function and egg quality. This project will study the basic mechanisms of how cumulin works in the ovary. We will then develop an assay to measure it as a biomarker of human egg quality and quantity. New approaches in fertility preservation for cancer survivors will be developed using cumulin.
Activation Of GDF9 Regulates Human Folliculogenesis

Summary
GDF9 is a key regulator of fertility in female mammals, as it controls the process of folliculogenesis. In this grant, we will demonstrate the importance of GDF9 in human folliculogenesis, determine the mechanisms that activate GDF9 and show why aberrant GDF9 activation leads to ovarian disorders. Collectively, the outcomes of this proposal will increase our understanding of the fundamental mechanisms that regulate ovarian folliculogenesis and provide new avenues to manipulate this process.
Characterising Signals Important For Lymphangiogenesis During Development And Disease.

Summary
Lymphatic vessels are a vital component of the cardiovascular system. Abnormalities in the growth and development of lymphatic vessels are associated with human disorders including cancer, lymphoedema and inflammatory diseases. The focus of this application is to characterise signals that direct the construction of lymphatic vessels, with the aim of identifying targets to which novel therapeutics for the treatment of lymphatic vascular diseases could be generated.

Summary
A protein first identified by our research group, called insulin-like growth factor binding protein-3 or IGFBP-3, has been shown to be a potent inhibitor of the growth of cancer cells. High levels of IGFBP-3 in the bloodstream are associated with a decreased risk of several cancer types, including breast cancer. However, the way in which this protein prevents cancer cells from growing is poorly understood.

High levels of IGFBP-3 in the bloodstream are associated with a decreased risk of several cancer types, including breast cancer. However, the way in which this protein prevents cancer cells from growing is poorly understood. This project will investigate an entirely novel idea, developed in our laboratory, that the actions of IGFBP-3 are intimately connected with the actions of another known cell growth inhibitor called transforming growth factor beta (TGFbeta). We have found that these two proteins initiate the same sequence of events leading to growth inhibition in breast cancer cells, and that a receptor protein required for TGFbeta activity is also needed for IGFBP-3 to be inhibitory. Our work has the potential to explain for the first time exactly how IGFBP-3 stops cancer cells from growing. This is important because it is an abundant protein in the body, and understanding how it acts may lead to the development of new approaches to cancer therapy that exploit our findings.Read moreRead less
