Funding Amount
$2,616,397.00
Summary
This study will track 11,000 Australian adults over 12 years to determine how many develop diabetes, obesity, kidney and heart disease. The study will develop ways to best predict those who are going to develop these conditions before they have arisen, and will explore a range of novel risk factors to better understand these conditions.
Epigenetic Programming Of Immune Development In Utero: Role Of The Maternal Environment In The Allergy Epidemic
Funder
National Health and Medical Research Council
Funding Amount
$764,463.00
Summary
This study will provide new insights into the development of allergic disease. Specifically, we will explore the hypothesis that allergic disease and other disorders or immune dysregulation occur as a result of gene-environmental interactions in early life, and that these events begin in pregnancy when the developing fetus is still developing and most susceptible to these effects.
How Does NF-kB2 Regulate Thymic Selection To Prevent Organ-specific Autoimmune Disease?

Summary
Autoimmune diseases like type 1 diabetes and thyroiditis arise from defects that cause the immune system to confuse self and non-self. Normally, this distinction is programmed in the thymus. We recently identified the gene that causes a form of autoimmune disease. We also made an important discovery about how the thymus gland regulates self-non-self discrimination. We will build on these two discoveries to gain a precise understanding of how the immune system normally avoids autoimmune disease.

Funding Amount
$362,570.00
Summary
The injection of a single sperm into the egg (ICSI) has been the main IVF treatment for men with poor sperm quality since 1993 but is now often used for other types of infertility. Concern has been raised about the health of the children. We will approach >800 parents and their adult sons conceived using ICSI and will assess his general health and development, and fertility. This work will improve patient counselling and practice guidelines, and direct research into the safety of ICSI.
Epidemics, mortality and longevity in Tasmania, 1838-1930. This project will investigate areas of contemporary importance that can only be explored using historic-demographic data. National benefits include (1) gaining a better understanding of how epidemics spread through families and communities, and possible mortality and case-fatality rates, to assist in preparation for future epidemics; (2) improved accuracy in projecting older-age mortality and population ageing in Australia and other coun ....Epidemics, mortality and longevity in Tasmania, 1838-1930. This project will investigate areas of contemporary importance that can only be explored using historic-demographic data. National benefits include (1) gaining a better understanding of how epidemics spread through families and communities, and possible mortality and case-fatality rates, to assist in preparation for future epidemics; (2) improved accuracy in projecting older-age mortality and population ageing in Australia and other countries; and (3) more precise estimates of women's capacity to naturally conceive and carry to term by characteristics such as her age, her partner's age, and her number of previous births. The project will also result in augmentation of a unique publicly available dataset.Read moreRead less
Chromosomes are structures that carry genes in all our cells. Every human cell has 46 chromosomes. In the nucleus of eukaryotic cells, DNA is highly folded and compacted with specific proteins into a dynamic polymer called chromatin. Gene expression, chromosome division, DNA replication, and repair all act, not on DNA alone, but on this chromatin template. The discovery that enzymes can (re)organise chromatin into accessible and inaccessible configurations revealed mechanisms that considerably e ....Chromosomes are structures that carry genes in all our cells. Every human cell has 46 chromosomes. In the nucleus of eukaryotic cells, DNA is highly folded and compacted with specific proteins into a dynamic polymer called chromatin. Gene expression, chromosome division, DNA replication, and repair all act, not on DNA alone, but on this chromatin template. The discovery that enzymes can (re)organise chromatin into accessible and inaccessible configurations revealed mechanisms that considerably extend the information potential of the genetic code. In addition, it is now established that chromatin structural features can influence gene expression. In vitro studies support a model in which chromatin functions as a barrier for the access to DNA. Therefore this organization has to be tighly regulated and dynamic to allow the protein-DNA interactions critical for nuclear functions. Importantly genome organisation provides in addition to genetic information another layer of information, so called epigenetic, which by definition means that it is stably inherited throughout cellular divisions, yet it is not encoded genetically. Thus each cell type will display a specific epigenome. We have recently constructed small human minichromosomes, which are much easier to study than the much larger normal chromosomes. The present project proposes to define the epigenetic feature across an entire human chromosome using our minichhromosomes as working models. The outcome will be a significant gain in our knowledge on the processes underlying epigenetic regulation, the organisation of specialised chromatin domain, and behaviour of the chromosomes.Read moreRead less
Reducing Prolonged Workplace Sitting Time In Office Workers: A Cluster-randomised Controlled Trial
Funder

Funding Amount
$524,613.00
Summary
Groundbreaking Australian research shows that sitting for too long, which is routine for most office workers, contributes to overweight and to a greater risk of developing diabetes and heart disease. In over 300 desk-bound office workers, this world-first study will assess the effectiveness of an innovative workplace program aimed at reducing and breaking up sitting time. It will identify practical ways for Australian office workers to minimise unhealthy effects of sitting too much at work.
Identifying genes that influence clinical course and susceptibility in multiple sclerosis. This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it.

This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it. Crucial new knowledge identified will benefit other major areas of MS research including epidemiology, immunology and neurobiology. Collaboration of 8 major Australian institutions is also important for this project and future studies. The team will have access to a new national MS GeneBank (platform) with samples from 2240 patients that should generate findings important to world-wide MS genetic knowledge.Read moreRead less
Mosquito-borne viruses - how they cause disease and novel approaches to prevention. In Australia, Ross River virus (RRV) is the most common insect borne virus that affects human health. There were more than 60,000 confirmed cases of RRV between 1993 and 2008. While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community. This project has several national benefits. It will elucidate whether there is ....Mosquito-borne viruses - how they cause disease and novel approaches to prevention. In Australia, Ross River virus (RRV) is the most common insect borne virus that affects human health. There were more than 60,000 confirmed cases of RRV between 1993 and 2008. While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community. This project has several national benefits. It will elucidate whether there is an association between RRV strain and the severity of disease and if there are human factors that affect the seriousness of symptoms. Knowledge of both of these could provide new avenues for the design of prevention and treatment strategies.Read moreRead less
