The successful development of sperm requires the proper function of a number of biological processes. This grant investigates the way in which sperm are produced, the genes that are needed to control their development, and the way sperm propel themselves and fertilize the egg. The research also investigates how sperm are protected during their development from infection and immunological rejection, achieved in part by a special environment within the tubes in the testis where they grow. It appears that the general mechanisms that the body uses to combat infections are modified within the testis and the way in which this occurs may provide clues that could be applied to prevent the rejection of transplanted organs in general. Some of the substances that control these processes appear to play an important role in the body�s defense against infection. The grant also investigates the processes that are involved in the development of prostate cancer. These changes can occur over many years and the grant will study some substances that appear to be involved. The work will provide new knowledge that may assist in new tests to identify whether a cancer is slow or fast growing, thereby helping each man to decide the most sensible form of treatment. The grant will investigate how a group of proteins, that also are involved in the control of processes discussed above, assist the mother in protecting her baby during pregnancy. The outcomes will assist in the management of disturbances of pregnancy that may put the fetus at risk of survival.Read moreRead less

Infertility affects one in six couples and is an extremely distressing, expensive and frustrating experience for those that it afflicts. Through gaining a better understanding of the molecular and cellular processes governing ovulation and early embryo development, this team will devise new therapeutic strategies to improve the reproductive health of Australian women.
The foot soldiers of the immune system, the white blood cells, constantly march through the body seeking out invaders, but kept in check by the barrier of endothelial cells that lines the inside of blood vessels. When infection occurs, molecular messages are transmitted amongst the white cells and between white cells and edothelium, to activate the immune cells to pass out of the blood vessels and mount a defence.

When infection occurs, molecular messages are transmitted amongst the white cells and between white cells and edothelium, to activate the immune cells to pass out of the blood vessels and mount a defence. Unfortunatley, the activation system sometimes goes awry, resulting in inflammatory or allergic disease, such as arthritis or asthma. This team of researchers from the Hanson Institute in Adelaide, combining expertise in molecular and cell biology, protein chemestry, structual biology and animal models, has been working together for over 10 years, investigating the molecular mechanisms involved in controlling the formation and activities of blood vessels and white blood cells. This program seeks to further that understanding, and to develop drugs that have the potential of ameliorating the inflammatory condition.Read moreRead less

Preconception and early pregnancy is a critical time for a women's health and that of her future child. New research suggests that a woman's genetic potential, her lifestyle and the physical and socioeconomic environment in which she lives, and her biological and social relationship with her male partner, all impact on the long term health of her baby.

New research suggests that a woman's genetic potential, her lifestyle and the physical and socioeconomic environment in which she lives, and her biological and social relationship with her male partner, all impact on the long term health of her baby. Abnormal events around the time of conception and in early pregnancy can predispose a newborn to later occurrence, in adult life, of conditions including heart disease, diabetes, obesity and stroke. These adverse events originate in the way that eggs and sperm develop, the uterus is prepared for implantation, the attachment of the early embryo to the lining of the uterus and subsequent growth of the placenta. This Program will study the early life events that promote or limit development of a baby's true potential for successful and healthy life. A better understanding of how lifestyle and environment interact with genes and biology to facilitate optimal growth of the fetus will underpin new preventative measures and therapeutic treatments for infertility, miscarriage and other reproductive disorders. The knowledge gained will inform health policy and clinical practise to improve reproductive health in all Australian women and promote healthy development in all Australian children. The team of researchers is a world-class group of clinicians, scientists and epidemiologists who have made major contributions to our understanding of this area. This team will interface with clinics and hospitals that engage with women prior to and during pregnancy, while having the influence to alter clinical and health practices as well as public health policies. The team will utilize the latest, most technologically advanced laboratory methods and clinical skills, including gene profiling, imaging of early pregnancy, randomised clinical trials and access to the best epidemiological and statistical assessments.Read moreRead less

Summary
The world is confronting a major new epidemic of premature heart disease that is being driven by a global increase in obesity. There are several factors that contribute to the increased risk of heart disease in overweight and obese people. One is a low blood level of the “good” HDL cholesterol that normally protects against heart disease. Another relates to a decreased ability to remove cholesterol from the walls of arteries where it builds up to cause heart disease.

There are several factors that contribute to the increased risk of heart disease in overweight and obese people. One is a low blood level of the “good” HDL cholesterol that normally protects against heart disease. Another relates to a decreased ability to remove cholesterol from the walls of arteries where it builds up to cause heart disease. A third is the fact that obesity is associated with a state of chronic inflammation of the blood vessels. This inflammation not only accelerates the development of heart disease but also makes people who have cholesterol accumulated in their arteries more likely to actually have a heart attack. And a fourth is the fact that the lining of blood vessels does not function normally in overweight and obese people. This loss of normal function is a very early sign of future heart disease. These factors are closely inter-related, with the “good” HDL playing a central role in removing cholesterol from arteries, inhibiting arterial inflammation and promoting normal function and repair of the lining of blood vessels. HDL is complex, consisting of a mixture of several subpopulations of particles that vary in shape, size and composition. Furthermore, these HDL subpopulations are continually remodelled as they circulate in blood in reactions promoted by a number of blood factors that change their size and composition. A major component of the research to be conducted in this program relates to understanding how the HDL subpopulations in human blood are regulated and how they protect against heart disease. The applicants have already made major contributions to understanding the functions of the “good” HDLs, how they take cholesterol out of cells in the artery wall, how they inhibit inflammation of the arteries and how they improve the function of the artery lining. We propose to extend these studies to establish how these protective functions can be enhanced, to find out which of the HDL subpopulations are most protective, and to identify how to increase the most protective HDLs in people at risk of heart disease.Read moreRead less
To understand the genetic basis of two of the most important cancers in women, breast and ovarian cancer. The team has already identified one gene that confers a very high risk of breast cancer and may account for a large proportion of 'familial' breast cancer. Their aim is to identify additional predisposition genes and to determine their normal function in the cell, as well as the way in which they contribute to the development of cancer
