Summary: In early life the brain undergoes rapid growth and remodelling, a process regulated by many factors including the insulin-like growth factor (IGF) system, which potently enhances nerve cell (neuron) survival. Similarly, this system is active in response to brain injury such a stroke, but it may also enhance tumor survival. The regulation of availability of IGFs to the neuron is critical in all these processes. IGF binding protein-2 (IGFBP-2), which is highly abundant in the developing or damaged ....

Summary: Breast cancer is the most commonly diagnosed form of cancer in Australian women, accounting for 26% of diagnosed cancers and 21% of cancer deaths among women. One in fourteen Australian and one in nine women worldwide will develop breast cancer in their lifetime. Significantly, approximately one in four of those diagnosed will die from their disease. The primary factor that determines survival is early diagnosis and treatment. Indeed, the primary tumour itself rarely causes death. Rather, the di ....

Summary: The insulin-like growth factor (IGF) system of growth factors and their regulatory proteins is essential for normal growth, but is also involved in a number of overgrowth disorders. Some clinical studies have shown that a high level of IGF-I in the blood increases the risk of breast cancer in some women, but if the protein which carries it in the circulation, IGFBP-3, is also high, the risk is reduced. It has therefore been suggested that IGFBP-3 may be useful in the treatment of breast cancer. ....

Summary: The growth of all tissues in the body depends on many growth factors, hormones and other proteins which work together to control cell division. Some of these factors stimulate the division of the cells which make up the body tissues, and some inhibit it, so that a balance of these stimulators and inhibitors ensures that tissues do not grow too fast, or too large. The development of breast cancer and the growth of breast tumours is thought to be due to uncontrolled or faulty actions of the protei ....

Summary: Steroid hormones, such as oestrogen and cortisol, act in the body by binding a family of proteins (nuclear receptors) that bind directly to the DNA to regulate genes. The mechanisms underlying this process are complex and involve recruitment of additional molecules or coactivators to improve efficiency. Recently a novel coactivator was identified termed SRA, which remarkably is never made into protein in cells, rather exerting its effects as a RNA. We have identified a novel family of proteins t ....

Summary: The insulin-like growth factors are small proteins involved in the growth of most tissues. Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D. These two vitamins are important in cell growth and in the way certain ....

Summary: Our skin protects us from damage, dehydration, infection and harmful UV radiation. At the same time, we expect it to remain healthy, smooth and looking good. How the skin, and more particularly its upper layer, the epidermis, adapts to all these requirements is a complex problem yet to be fully understood. This question forms the basis of our project proposal. The epidermis is a continuously self-renewing tissue, in which cells have an average life of 30 days before they are invisibly shed to th ....

Summary: Growth hormone is responsible for normal postnatal growth, is an important metabolic regulator in starvation, and has many useful therapeutic applications, including forms of cardiac insufficiency, Crohns disease and, it is thought, amelioration of ageing. The means whereby GH brings about these changes are not known, although we do know a considerable amount about how the individual domains within the GH receptor signal. What we do not know is which genes are regulated by GH in these processes, ....
